Answers

Answer 1

To draw the Earth cross section at a scale of 1:100,000,000 (1cm = 1000 km), follow these steps:

Prepare your drawing materials: You will need a millimeter ruler, a compass with a very fine pencil or a fine-tip pen, and a blank sheet of paper.

Determine the size of your drawing: Decide how big you want your drawing to be on the paper. For example, if you want the drawing to fit within a square of 10 cm x 10 cm, you will need to allocate that space on your paper.

Set the scale: Establish the scale of 1:100,000,000. This means that every centimeter on your drawing represents 1000 kilometers of actual distance. So, for example, if you want to represent a depth of 12 km, you will draw a line that is 0.12 cm long.

Draw the boundaries and layers: Start by drawing the boundaries and layers at their respective depths. Use solid lines to indicate changes in chemistry and dashed lines to indicate changes in mechanical properties.

Here's a step-by-step guide to drawing the Earth cross section based on the provided depths:

Draw a horizontal line at the bottom of your paper to represent the surface of the Earth.

Measure 0.12 cm (representing 12 km) from the surface line and draw a solid line across the paper. Label it as the oceanic Moho.

Measure 0.35 cm (representing 35 km) from the surface line and draw another solid line across the paper. Label it as the continental Moho.

Measure 1.5 cm (representing 150 km) from the surface line and draw a dashed line across the paper. Label it as the transition from lithosphere to asthenosphere.

Measure 3.5 cm (representing 350 km) from the surface line and draw another dashed line across the paper. Label it as the bottom of the very soft asthenosphere.

Measure 7 cm (representing 700 km) from the surface line and draw a solid line across the paper. Label it as the top of the hard mesosphere.

Measure 29 cm (representing 2900 km) from the surface line and draw a solid line across the paper. Label it as the top of the core mantle boundary.

Measure 51 cm (representing 5100 km) from the surface line and draw a solid line across the paper. Label it as the outer core/inner core boundary.

Measure 63 cm (representing 6300 km) from the surface line and draw a solid line across the paper. Label it as the center of the Earth.

Remember to label each boundary or layer accordingly.

Add additional details: If desired, you can add additional details to your drawing, such as labeling the different zones or adding a key for the line types (solid and dashed).

Ensure that you maintain the scale throughout the drawing, using the ruler to measure and accurately represent the depths.

By following these steps, you should be able to create an accurate and scaled representation of the Earth cross section.

What evidence is there of a major earthquake in the Seattle area approximately 1,100 years ago, besides the uplifted wave-cut terrace at the south end of Bainbridge Island?

Answers

Studies of sedimentary deposits in the Puget Sound region have revealed evidence of a large earthquake that occurred around the same time as the uplifted wave-cut terrace at the south end of Bainbridge Island.

Evidence of a major earthquake in the Seattle area approximately 1,100 years ago can be found in the geological record. The deposits contain evidence of liquefaction, which is a process that occurs when the ground shakes so violently that the soil loses its strength and behaves like a liquid.

Additionally, the deposits contain evidence of landslides, which are caused by the shaking of the ground during an earthquake. Furthermore, the deposits contain evidence of ground deformation, which is caused by the shifting of the Earth's crust during an earthquake. All of this evidence suggests that a major earthquake occurred in the Seattle area approximately 1,100 years ago.

The earth: is a perfect sphere has an Equatorial diameter equal to polar diameter is roundish is a prolate ellipsoid

Answers

The Earth is not actually a perfect sphere, contrary to popular belief. Instead, it is an Oblate Ellipsoid. This means that although its Equatorial diameter is approximately equal to its polar diameter, it is slightly wider at the Equator than at the poles.

This "roundish" shape is due to the spinning of the Earth which causes it to bulge at the Equator. As such, it is not a sphere but a type of ellipsoid. Additionally, the large oceans on the planet contribute to this non-spherical shape.

The uneven distribution of gravity due to the Earth's rotation causes greater surface deformation than the oceans alone and further adds to the planet's elliptical shape. The Earth's non-spherical shape is also reflected in its gravitational field which is more pronounced at the Equator than at the poles, further distinguishing it from the perfect sphere.

Which of the following is most likely to cause pollution due to leaching through the soil profile? peat moss compost processed sewage sludge ammonium sulfate sulfur coated urea

Answers

Ammonium sulfate is the most likely cause of pollution due to leaching through the soil profile. Ammonium sulfate is a widely used inorganic fertilizer and is soluble in water.

Correct option is C.

When applied to the soil, it quickly dissolves in water and becomes available for plant uptake. However, when too much ammonium sulfate is added to the soil, the nitrogen and sulfate ions can leach through the soil profile and travel downward, eventually entering groundwater supplies and polluting them.

This can be especially problematic for water sources used for drinking or swimming as too much nitrate and sulfate can be toxic to humans. To minimize the risk of leaching, it is important that these fertilizers are used as recommended and should not be over applied to soil to reduce the risk of potential groundwater contamination.

Compute the amount of energy required to heat your house from 15 ºC to 25 ºC if the volume of air is 1000 m3? Assume that you only heat the air in the house and that you can ignore the water vapor in the air. The specific heat of dry air is 1005 J kg-1 K-1. Assume an air density of 1 kg m-3. The unit for the answer is in Joules but you do not need to put the unit in your answer or in scientific notion.

Answers

To compute the amount of energy required to heat your house from 15 ºC to 25 ºC, we can follow these steps.

First, we need to calculate the mass of the air in the house by multiplying the air density (1 kg/m³) by the volume (1000 m³), which gives us 1000 kg. Then, we calculate the temperature difference by subtracting the initial temperature (15 ºC) from the final temperature (25 ºC), resulting in 10 ºC.

Next, we multiply the mass of the air (1000 kg) by the specific heat of dry air (1005 J/kg-K) and the temperature difference (10 ºC). This gives us the energy required to heat the air, which is 10,050,000 J or 10.05 MJ.

Answers

The largest tides occur When the moon is in perigee during the month of January and there's a full or new moon.

The tidal pattern for Southern California coasts is diurnal mixed, meaning that during the month the region experiences both semidiurnal and diurnal tidal movements.

Correct option is A and D.

Semidiurnal tides are characterized by two high tides and two low tides per day, with the highs and lows of each tide being approximately equal. Diurnal tides only have one high and one low tide per day, usually around the same time. The mixed pattern of Southern California is formed from both the hemispheric semidiurnal and the regional diurnal tide patterns in the ocean.

This mixed pattern is caused by several different factors like the size of the ocean, the position of the moon and unique characteristics of the coastline. The regional diurnal pattern is more frequent and pronounced in Southern California due to the more direct moon-tide connection as well as its “bathtub” shape.

Why were there so many more deaths in Haiti than in other areas with large populations? What are some strategies that builders can use to decrease death and destruction in earthquake prone areas?

Answers

Through a process called "induced seismicity" or "earthquake triggering," earthquakes can cause further earthquakes. The United States state of Oklahoma recorded this phenomenon in 2010.

The P-wave (principal wave), in terms of seismic waves, arrives first during an earthquake. The secondary wave, or S-wave, arrives next. Following P-waves, shear waves called S-waves generate a side-to-side motion that is perpendicular to the direction of wave propagation.

Early P-wave warning systems can considerably reduce the number of fatalities and property damage in earthquake-prone regions. Before the more destructive S-waves and surface waves reach a specific site, these systems use seismic networks to detect the initial P-wave of an earthquake. People and automated systems can respond right away to safeguard lives and lessen damage to infrastructure by seeing the P-wave and giving advanced notice.

Haiti had insufficient mechanisms in place to lessen the effects of earthquakes because it is a developing nation with limited resources and infrastructure. The higher casualties were a result of the lack of preparation.

Geophysical methods have been used to help overcome the limitation of wireline logs and cores in physically describing a reservoir. This limitation is only able to provide information in the immediate vicinity of the wellbore.

Correct option is E.

Gravity and magnetics are geophysical methods used to discern subsurface properties at greater depths than what is detectable by wireline logs. Three-dimensional (3-D) seismic techniques allow for the imaging of structures and boundaries in the subsurface. The result of 3-D seismic typically gives a higher resolution than what is seen in 2-D seismic.

Refraction methods are used to map subsurface geological features by analyzing the amount of time different waves of seismic energy take to travel between two points. Lastly, cross-well tomography involves sending and receiving wave energy through one well and receiving the resulting waves in another, with the purpose of imaging the subsurface.

Correct option is E.

Plants that grow without constraint exhibit determinate
growth.
Group of answer choices
True
False

Answers

The statement "Plants that grow without constraint exhibit determinate growth" is false. The correct statement is: "Plants that grow without constraint exhibit indeterminate growth", according to the concept of plant growth.

Plant growth can be categorized into two main types: determinate growth and indeterminate growth. Contrary to the false statement, plants that grow without constraint actually exhibit indeterminate growth. Indeterminate growth refers to the continuous development of plant structures throughout their lifespan, allowing them to increase in size and produce new leaves, branches, and flowers. This growth pattern is commonly observed in many perennial plants and allows for continuous expansion and development. In contrast, plants with determinate growth have a predefined limit to their growth, typically reaching a certain size or height and then ceasing further growth.

Understanding the distinction between determinate and indeterminate growth is crucial in studying and managing plant growth for various purposes such as agriculture, horticulture, and ecological research.

Answers

People has been using maps for centuries. One can argue that that was an old GIS except that science was missing.

Correct option is C.

Maps have been an essential part of human life for centuries, used for navigation, exploration and boundary marking. However, without the scientific method and modern technology, they lack the precision, accuracy and detail of a modern geographic information system(GIS). GIS technology collects, organizes and analyzes geographic information.

All data points are assigned coordinates and a geographic location to give context and allow connections to be made between those points and larger scale observations. To create a GIS, information about the physical world is gathered, sorted and displayed using mathematics, statistics and computer graphics.

What would a graph of solar altitude look like for the Equator (0°) and for a location in the Arctic (72°N)? On the graph paper provide, graph SA for Jacksonvile on one day each month. Then do the same for the Equator and 72°N. After you have done this use the monthly average temperatures and add them to your graph. Describe your findings. You can use the below graph or just download some blank graph paper. You can upload a picture of a hand drawn chart or do it online. Use the data from your data of SA from the above question.

Answers

A graph of solar altitude for the Equator (0°) and for a location in the Arctic (72°N) would look like a bell curve. The graph would show the highest solar altitude at noon and the lowest solar altitude at sunrise and sunset.

For Jacksonville, the solar altitude would be highest in the summer months and lowest in the winter months. The solar altitude for the Equator would be highest in the summer months and lowest in the winter months, but the solar altitude for the Arctic would be highest in the winter months and lowest in the summer months.

When the monthly average temperatures are added to the graph, it is clear that the solar altitude and temperature are related. As the solar altitude increases, the temperature increases. This is because the sun's energy is absorbed by the Earth's surface, which warms the air. Conversely, as the solar altitude decreases, the temperature decreases.

This is because the sun's energy is not being absorbed as much, so the air does not warm as much. Overall, the graph of solar altitude and temperature shows that the sun's energy is a major factor in determining the temperature of a location.

The following are the correct statements:

Air diverges at the Intertropical Convergence Zone, causing a band of clouds and high precipitation is True.A climate that continues to become colder is an example of an unstable system is True.The relationship of plant growth and temperature in actual earth environments is NOT a linear relationship is True.

The statement "Although extreme values or events, such as intense rainstorms or very hot temperatures, are often of short duration and occur rarely as compared to the norm, the probability of occurrence is the same at any one time. Since a 100 -year flood (by definition) has a 1% probability of occurrence, that probability remains the same each year. It does not matter if it occurred recently or not. So if you are planning for a high-priority or high-value situation, be sure to take extreme events into consideration" is False.

Air diverges at the Intertropical Convergence Zone, causing a band of clouds and high precipitation. This is true. The Intertropical Convergence Zone is also known as the doldrums, which is an area near the Equator where the prevailing trade winds of the Northern Hemisphere and the Southern Hemisphere come together. This zone is characterized by low atmospheric pressure, warm temperatures, and humid conditions.

A climate that continues to become colder is an example of an unstable system. This statement is true. The climate system is considered unstable if a change in the system's state results in further changes that push the system towards a different state.

The relationship of plant growth and temperature in actual earth environments is NOT a linear relationship. This statement is true. The relationship between plant growth and temperature is not linear. Temperature has both positive and negative effects on plant growth. For instance, low-temperature stress, such as freezing, drought, or flooding, may reduce plant growth.

Although extreme values or events, such as intense rainstorms or very hot temperatures, are often of short duration and occur rarely as compared to the norm, the probability of occurrence is the same at any one time. Since a 100 -year flood (by definition) has a 1% probability of occurrence, that probability remains the same each year. It does not matter if it occurred recently or not. So if you are planning for a high-priority or high-value situation, be sure to take extreme events into consideration is False.

This statement is incorrect because the probability of occurrence for an extreme event is not the same every year. While a 100-year flood has a 1% chance of occurring in any given year, it does not imply that it will happen precisely every 100 years. The likelihood of a 100-year flood happening is higher in some years than in others, and previous flooding events may increase the likelihood of future flooding.

describes the process when cooler air with pollutants is trapped near the ground with warmer air overtop. This occurs in major cities like Chattanooga, TN and Los Angeles, CA that are located near water and mountains, and have lots of air emission sources.

Answers

Temperature inversion describes the process when cooler air with pollutants is trapped near the ground with warmer air overtop.

How does temperature inversion happen ?

When the sky is clear, there is nothing to stop the sun's heat from warming the ground during the day. This causes the air near the ground to warm up. At night, the ground cools down, but the air near the ground stays warm because it is insulated by the ground. This creates a temperature inversion.

Mountains can also cause temperature inversions. When the wind blows over a mountain, it is forced to rise. As the air rises, it cools down. This can cause the air temperature to decrease with altitude, creating a temperature inversion.

Water can also cause temperature inversions. When the wind blows over water, it picks up moisture. This moisture can then condense and form clouds or fog. The clouds or fog can block the sun's heat, which can cause the air temperature to decrease with altitude, creating a temperature inversion.
