What is a topographic map, and what does it show you?
A topographic map is a detailed and accurate representation of man-made and natural features on the Earth's surface.
There are various types of maps for various purposes. Topographic maps identify different ground features like Relief(mountain, slope), Hydrography(lakes, river), Vegetation, Boundaries, Transportation ways etc. The topographic map is a two-dimensional representation of the Earth's three-dimensional landscape. Therefore, a map will never be entirely up to date. Changes may take place in landscape features regularly resulting in maps becoming dated, although the rate of agedness varies depending upon location.
Topographic maps are based on topographical surveys. They are used in geographic planning, mining and other earth based endeavors. Hikers use topographic maps to find trails and the steepness of slopes to plan their ascent.

What does the 1:100 scale mean?
A 1:100 scale represents an object or subject that is 100 times smaller than its true world size of 1. As a result, while reading this scale, 1 unit is comparable to 100 units.
A 1:100 scale is most typically coupled with millimeters, cementers, and/or meters when used with metric units, and may be used for map reading, where a 1cm measurement would be equal to 1 meter (100 times bigger) when measured with a scale rule.
1 centimeter (on the map) equals 100 m (on the ground)
Take the left side of the ratio, then the right side, multiplies each by 1 cm on the ratio scale.

What does grain size in a sedimentary rock reveal about its history? Explain your answer. Give an example.
Rounded sediment tells you that the rocks traveled quite some distance, rolling around and bumping into each other. The larger the grain size the quicker the sediment was moving and depositing.
Explain the term grain size.
The diameter of a single grain of silt or the lithified particles in clastic rocks is known as grain size (or particle size). Other granular substances may also be covered by the phrase. The crystallite size, on the other hand, refers to the size of a single crystal inside a particle or grain. There are several crystals that can make up a single grain. From very tiny colloidal particles, to clay, silt, sand, gravel, and cobbles, to boulders, granular material can come in a variety of sizes.
In the American Wentworth scale (also known as the Udden-Wentworth scale), size ranges provide the upper and lower bounds of the classes that are assigned names. The Wentworth scale was modified by W. C. Krumbein to create the Krumbein phi () scale.

A mid latitude cyclone is steered driven by the
Answer:
Explanation:
A mid-latitude cyclone, also known as an extratropical cyclone, is a type of weather system that forms in the middle latitudes and can bring significant impacts to the areas it affects. These cyclones are driven by the wind patterns in the mid-latitudes and are influenced by several meteorological factors.
The prevailing westerlies, which are winds that blow from the west to the east in the mid-latitudes, play a key role in steering these cyclones. The westerlies can cause a mid-latitude cyclone to move from west to east across the middle latitudes.
The pressure gradient, which is the difference in atmospheric pressure between two points, also affects the movement of mid-latitude cyclones. As the pressure gradient increases, the winds become stronger, which can help to steer the cyclone.
The Coriolis effect, which is the result of the earth's rotation, also plays a role in the movement of mid-latitude cyclones. The Coriolis effect causes the winds to turn to the right in the northern hemisphere and to the left in the southern hemisphere, which can cause the cyclone to turn and move in a particular direction.
The position of high and low pressure systems can also influence the steering of a mid-latitude cyclone. For example, if a strong high-pressure system is located to the east of the cyclone, it can cause the cyclone to move towards the east.
In general, mid-latitude cyclones bring precipitation, strong winds, and sometimes severe weather to the areas they impact. They can cause significant disruptions to daily life, including flight cancellations, power outages, and road closures. It is important to stay informed and to take necessary precautions when a mid-latitude cyclone is expected in your area.

Groundwater is a better source of water because pumping this source does notimpact streams and wetlands. True or False
True Groundwater is a better source of water because it is unaffected by pumping and does not affect wetlands or streams.
Which is Superior? Surface water or groundwater?As long as the sources are unpolluted and the water is sufficiently treated, both surface water and groundwater can generally provide safe drinking water. There are numerous advantages to using groundwater over surface water.
Does groundwater have an impact on streams?Water is discharged into rivers and streams either directly through river beds and banks or indirectly through springs as groundwater tables rise in the winter and spring. Many of California's rivers and streams continue to flow long after the rain has stopped.
How does pumping affect groundwater?By either intercepting groundwater flow that discharges into the surface-water body under natural conditions or by increasing the rate of water movement from the surface-water body into an aquifer, groundwater pumping can alter how water moves between an aquifer and a stream, lake, or wetland.

Early in the 20th Century chemists created a new formulation for gasoline that made engines run much smoother by adding dissolved mercury.a. trueb. false
False. Mercury was never added to gasoline as a fuel additive to improve engine performance.
The claim that early 20th-century chemists added dissolved mercury to gasoline to improve engine performance is false. While chemists did experiment with various additives to improve the properties of gasoline, including lead-based compounds and oxygenates such as ethanol and methanol, there is no record of mercury being used for this purpose.
In fact, mercury is a highly toxic metal that can cause serious health problems, including neurological damage, when ingested or inhaled. As a result, the use of mercury in any form as an additive has been banned in many countries, including the United States.
Furthermore, it is important to note that the use of gasoline additives, in general, has come under scrutiny due to their potential adverse effects on human health and the environment. While some additives, such as detergents and antioxidants, are still commonly used, others like lead and MTBE have been phased out or banned altogether.

In the Northern Hemisphere, surface air moves clockwise in a high-pressure system and counterclockwise in a low-pressure system. Surface air motion is out of a high-pressure system and into a low-pressure system.
The movement of air in the atmosphere is affected by differences in air pressure. High-pressure systems are areas where the air pressure is higher than the surrounding areas, while low-pressure systems are areas where the air pressure is lower than the surrounding areas.
In the Northern Hemisphere, the Coriolis effect causes the surface air to move clockwise around a high-pressure system and counterclockwise around a low-pressure system. This means that in a high-pressure system, the surface air is moving outwards away from the center of the system, while in a low-pressure system, the surface air is moving inwards towards the center of the system.
As the air moves from high-pressure to low-pressure areas, it creates winds. The stronger the pressure gradient (difference in pressure between two points), the stronger the winds will be. Understanding the direction of surface air movement is important for predicting weather patterns, as different air masses with different pressures can create various weather conditions, such as thunderstorms, hurricanes, or clear skies.
