Pesticides sometimes create contradictory results. Insecticides sprayed in rice fields created 500 to 1000 times more than in fields not sprayed

Answers

Answer 1

Pesticides sometimes create contradictory results. Insecticides sprayed in rice fields created 500 to 1000 times more insects than in fields not sprayed.

Given that the usual goal of applying pesticides is to manage or reduce insect populations rather than to raise them, this situation implies a conflicting outcome.

Over time, certain pesticides' effectiveness against some insect populations might be compromised. It can result in an increase in pest populations rather than a decrease if the pests in the rice fields have evolved a resistance to the specific pesticides employed.

The natural equilibrium of ecosystems can be disturbed by insecticides. By eradicating some insect species, it may open up ecological niches or resources that other insect species may take advantage of, leading to an increase in their populations.

which is characteristic of low head dams? they pose hazards both above and below dams they pose few hazards to inboard-powered boats they may be crossed safely at a 45-degree angle to their faces they usually have strong re-circulating currents just above them

Answers

The characteristic of low head dams is that they pose hazards both above and below dams.

Hence, the correct answer is option a.

Low head dams are known for creating dangerous conditions both upstream and downstream. The presence of a low head dam can lead to the formation of a hydraulic jump, which creates a recirculating current and a hydraulic roller effect just below the dam.
These conditions can trap and drown people, boats, or other objects that enter the turbulent water below the dam. Additionally, the spillway and turbulent water above the dam can pose risks to boaters and individuals who may be swept over the dam. Therefore, low head dams should be approached with caution, and it is important to be aware of the hazards they present.

The given question is not properly written. Hence, the proper question is:

Which is characteristic of low head dams?

a. they pose hazards both above and below dams

b. they pose few hazards to inboard-powered boats

c. they may be crossed safely at a 45-degree angle to their faces

d. they usually have strong re-circulating currents just above them

Final answer:

Low head dams possess strong recirculating currents just below them which pose significant hazards both above and below the dams. Attempting to cross them at a 45-degree angle would not mitigate these risks. These dams also pose threats to the local aquatic ecosystems.

Explanation:

The characteristics of low head dams can sometimes be misleading due to their deceptively tranquil appearance. However, they pose significant hazards both above and below the dams. One of the main risks associated with these dams is the strong recirculating currents present just below them. These currents create a 'drowning machine' effect which can trap people and objects in a continuous, cyclical motion.

These dams are equally dangerous for inboard-powered boats as well due to these currents. Attempting to cross them at a 45-degree angle to their faces would not make them any safer. Low head dams also pose threats to aquatic ecosystems, disrupting the flow of the river/streams and affecting the migration and spawning patterns of various fish species.

Overall, while low head dams may appear harmless from a distance, they hold significant danger and require utmost caution when navigating around them.

c-) Why maybe shouldn't be a nice idea to explore Venus.

Answers

Venus is the second planet from the Sun and is often thought to be a placeholder for what Earth could become. It’s one of the brightest objects in the night sky and has been known since ancient times.

It has a thick and toxic atmosphere composed mainly of carbon dioxide that traps the Sun's heat and creates an incredibly hot surface. This natural environment has made Venus an alluring target for exploration.

Exploring Venus could be good for science because of its similarities to Earth. By studying Venus, planetary scientists may be able to learn about the environmental circumstances that turn a temperate world like Earth into a raging inferno like Venus. Additionally, technological developments being made for exploration of Venus could also be used to explore other planets.

On the other hand, exploring Venus has its challenges. Venus’s thick atmosphere makes it difficult to send anything through it, and its intense heat would likely melt any spacecraft sent to its surface. If a spacecraft is able to make it to the surface, it would only have a handful of minutes to take pictures due to the hostile environment. This makes exploring Venus a difficult endeavor.

Based on the information, answer the following question. a) Sketch a diagram showing a typical subsurface profile in a limestone area, which may cause concern about the deep foundation work to be carried out b) Discuss how the weathering effect could result in the unique subsurface geological features? c) Explain how a resistivity survey could further assist in characterising the subsurface condition of this area? d) Concerning on deep foundation work and your sketch in (a), discuss the potential problems and methods to overcome the issues.

Answers

A typical subsurface profile in a limestone area is shown in the diagram below. This subsurface profile exhibits an increasing density/hardness with depth, with a significant change at a certain depth followed by a more or less a uniform layer at a greater depth.

Limestone is highly weather resistant in comparison to other substrata, as its properties have a moderate to low susceptibility to weathering. It is known that physical and chemical weathering processes cause a breakdown of rock due to hydrolysis and oxidation. This results in the presence of karst features, such as caverns, fissures, and sinkholes, which can be very problematic for deep foundation engineering works.

Using a resistivity survey is beneficial in characterizing the subsurface formations in a limestone area. These surveys can also provide an indication of karst features. By detecting variations in the electrical resistivity, the survey can detect any changes in the subsurface topography or any pockets of water or rock type.

Potential issues posed by the limestone subsurface can be addressed with a combination of foundation designs. For example, if there are karst features present, which can cause instability, deep foundations can be used. If not, shallow foundations can be employed, with caution taken to ensure that all karst features are identified and not subjected to excessive loading.

2. Based on the movie list two geologic observations that were factually incorrect or exaggeratedrelated to subduction zone volcanism and/or precursors to a subduction zone volcanic eruption.

Answers

The following are three geologic observations that were accurate in terms of subduction zone volcanism or precursors to a subduction zone volcanic eruption:

1. a.) The hot spring's lava eruption, atmospheric CO₂, a variety of earthquakes, and the presence of sulfur dioxide (SO₂) in the water supply are all examples of this.

b.) The subduction zone subsides a significant portion of the land beneath, resulting in a massive earthquake beneath the surface and a volcanic eruption because it is the most significant crash site on Earth.

The volcanic eruption in Dante's Peak was represented by a massive pyroclastic cloud, in which rocks covered in dense gaseous clouds break up and fly all over the sky.

c. ) A seismograph is a device that is used to detect earthquakes. It uses a graph called a seismographs to predict the reading of an earthquake. Since this mechanism allows for the detection of an earthquake, it is used to do so.

2. Two geologic observations regarding subduction zone volcanism and/or precursors to a subduction zone volcanic eruption that were either factually incorrect or exaggerated.

a.) Given that they had already looked at the seismographs and noticed the earthquake, they might have left earlier to avoid dying in a volcanic eruption.

b. ) As depicted in the movie, a iconoclastic cloud is approaching them at a greater rate, and they are attempting to eliminate it along with the pyroclastic rocks that are emerging from the volcano.

They were driving at a much faster speed than the pyroclastic clouds before that cloud was going to hit them, so they found a safe tunnel so that they could be saved because it was impossible for even one rock to miss hitting their car. Pyroclastic clouds are extremely destructive because they move very quickly and easily spread throughout the sky in a short amount of time.

Is it possible that some UFOs are intelligently controlled vehicles that were manufactured outside of the Earth? i.e., by an advanced ET civilization in the Galaxy.
Yes, please explain
No, please explain

Answers

No, it is not possible that some UFOs are intelligently controlled vehicles from outside the Earth.

Although some unexplained sightings of strange objects in the sky cannot be easily explained by phenomena of the natural world, there is no reliable evidence to support the claim that these objects are coming from an advanced extraterrestrial civilization in the galaxy.

For example, most sightings of UFOs do not follow established flight paths and patterns, nor do they feature standard navigational behavior that is expected if these unidentified objects were being intelligently controlled vehicles from an advanced civilization. Additionally, no physical evidence of extra-terrestrial craft or technology has been produced.

Thus, while it is possible that there are unidentified craft of some kind in our atmosphere, the likelihood that these are from an extraterrestrial origin is negligible.

Discuss the historic use of relative and absolute dating to develop the geologic time scale. Were relative dates or absolute dates first employed to develop this time scale? Explain your reasoning.

Answers

Relative dating was the first method employed to develop the geologic time scale. Relative dating is the process of determining the age of a fossil or rock layer in relation to other layers, without knowing the exact age.

This method was used to establish the relative order of the geologic time scale, which is the sequence of events in Earth’s history. Absolute dating, which is the process of determining the exact age of a fossil or rock layer, was then used to assign numerical ages to the relative time scale.

This allowed for the development of a more precise geologic time scale, which is still used today. Relative dating was the first method used to develop the geologic time scale because it was the only method available at the time. As technology and knowledge advanced, absolute dating was developed and used to refine the geologic time scale.

Answers

Metamorphic rocks are formed through the transformation of existing rocks due to changes in temperature, pressure, and/or chemical composition, resulting in the formation of new minerals and textures.

1. The texture of metamorphic rocks tells us about their pressure of formation.

2. all except b is an example of an external process.

3. deposition is the process where pieces of rock start collecting to form sedimentary rocks.

Sedimentary rocks are formed from the accumulation and cementation of sediments, which can include fragments of preexisting rocks, minerals, and organic matter.

4. You would expect an extrusive igneous rock to have all except b.

An extrusive igneous rock, also known as volcanic rock, is formed from lava that cools and solidifies on the Earth's surface. It typically has small or fine-grained crystals due to rapid cooling.

5. Basaltic magmas have less silica and form non-explosive volcanoes.

Basaltic magmas have lower silica content compared to other types of magmas. Lower silica content in basaltic magmas results in lower viscosity and ability to flow more easily. This fluidity allows gases to escape more readily, resulting in less explosive volcanic eruptions.

What differentiates a katabatic wind from a mountain breeze? Katabatic winds typically occur at higher altitudes than mountain breezes. Katabatic winds are seasonal, but mountain breezes occur throughout the year. Katabatic winds have higher speeds and lower temperatures than mountain breezes. Katabatic winds have lower speeds and higher temperatures than mountain breezes.

Answers

Katabatic winds are downslope winds that occur when cold, dense air flows from higher elevations to lower elevations. They are typically associated with cold temperatures and can reach high speeds.

Hence the correct answer is option c.

Katabatic winds, also known as downslope winds, are a type of wind that occurs when cold, dense air moves downhill under the force of gravity. These winds are often associated with mountainous regions and can have significant impacts on local weather patterns.

These winds are formed when cold air at higher elevations becomes denser and flows downhill due to gravity. As the air descends, it gains speed and compresses, leading to an increase in temperature. This process can result in strong and gusty winds.

Katabatic winds are prevalent in polar and alpine regions, where cold air accumulates on high elevation ice sheets or glaciers. They can occur both day and night but are usually stronger during nighttime when radiative cooling enhances the cold air's density.

Based on the information provided, here are the answers to the questions:

a) The given soil has a permeability coefficient (k) of [tex]3 * 10^(-7) m/s.[/tex]Permeability refers to the ability of a soil to allow water to flow through it. The degree of permeability can be identified as moderate to low, as the given coefficient indicates relatively slow water movement through the soil.

b) To determine the diameter of the measuring pipe, we need to use Darcy's Law formula, which relates the flow rate, cross-sectional area, and hydraulic gradient of the soil. However, the given information does not provide the flow rate or hydraulic gradient, so it is not possible to calculate the diameter of the measuring pipe.

c) To compare the permeability of the given soil with that of a sandy silt, we need information about the permeability coefficient of the sandy silt. Without that information, it is not possible to make a direct comparison or provide a conclusive answer.

d) Frost hardness refers to the resistance of soil to frost-related damage or swelling. The information provided does not specify the frost hardness of the given soil or the gradual sand.

c. Earth wobbles as it rotates, causing precession.
d. Earth experiences seasons.

Answers

1. Asterism: easily recognized group of stars; Constellation: group of stars represented by abstract or imaginary figure.

2. Earth's tilt causes seasons; Polaris not always at North Pole.

The distinction between an asterism and a heavenly body is that an asterism is: c. a gathering of stars addressed by an effectively perceived object, though a heavenly body is a gathering of stars addressed by some theoretical or nonexistent figure.

An asterism alludes to a more modest gathering of stars that structure a conspicuous shape or example inside a heavenly body. Groups of stars, then again, are bigger region of the sky assigned by unambiguous limits and frequently named after legendary or verifiable figures.

The Genuine assertion about the sky is: b. Polaris was not generally situated at the North Pole. Polaris, otherwise called the North Star, is right now found extremely near the North Heavenly Pole.

Nonetheless, because of the peculiarity of precession, the World's hub gradually changes its direction after some time, making the place of the North Divine Pole shift. This implies that Polaris has not forever been and won't generally be the North Star.

An article with an obvious visual greatness of +12 is: d. multiple times more splendid than the dimmest star detectable with the natural eye.
