Which agent of erosion causes the sandblasting of bedrock?
Sandblasting occurs when winds blow sand or silt against other rocks causing the rock to appear pitted (like a golf ball).
What are two major factors that control the development of soil in a given location regents?
Scientists attribute soil formation to the following factors: Parent material, climate, biota (organisms), topography and time.
What characteristics identify mountain landscape regions?
They usually have steep, sloping sides and sharp or rounded ridges, and a high point, called a peak or summit. Most geologists classify a mountain as a landform that rises at least 1,000 feet (300 meters) or more above its surrounding area. A mountain range is a series or chain of mountains that are close together.
Which change is most likely to occur in a landscape?
Which change is most likely to occur in a landscape if its climate changes from humid to arid? Vegetation will increase.
What is agent of soil formation?
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
Which rock unit appears to be the most resistant to weathering and erosion?
The explanation is that quartz is highly resistant to the types of weathering that occur at Earth’s surface. It is not affected by weak acids or the presence of oxygen. This makes it unique among the minerals that are common in igneous rocks.
Which type of air mass would most likely form over the Pacific Ocean?
Most Maritime polar air masses that affect the United States are formed in the north Pacific Ocean. Occasionally, however, maritime polar air forms in the North Atlantic Ocean, and moves into the New England states. 2. Maritime polar air is not as cold as continental polar air.
What was the most likely source region for the air mass over Pennsylvania?
The map of a portion of eastern North America shows a high-pressure center (H) and a low-pressure center (L), frontal boundaries, and present weather conditions. What was the most likely source region for the air mass over Pennsylvania? New York State.
Where are the Earth’s sedimentary rocks generally found?
You’re most likely to find sedimentary rocks near sources of water, which is where a lot of erosion takes place. You can find different types in riverbeds, ponds and coasts and throughout the oceans.
Which environmental factors most likely impact the formation of tornadoes in this area?
One area where most of the tornadoes occur is known as Tornado Alley. Which environmental factors MOST likely impact the formation of tornadoes in this area? air density and air pressure.
Where is continental tropical formed?
Continental tropical air masses originate in northern Mexico. They are characterized by clear skies and negligible rainfall. If one moves into the Great Plains and stagnates, a severe drought can result.
Which type of air mass most likely has high humidity and high temperature *?
Maritime air masses form over water and are humid. Continental air masses form over land and are dry. Therefore, an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.
Which condition is most likely to cause the formation of a temperature inversion?
Which condition is most likely to cause the formation of a temperature inversion? When a cold front moves over a land region that has warm, moist air, a transfer of energy occurs. Cold air sinks and pushes warmer air upward.
Which is responsible for creating wind?
Wind is air in motion. It is produced by the uneven heating of the earth’s surface by the sun. Since the earth’s surface is made of various land and water formations, it absorbs the sun’s radiation unevenly. Two factors are necessary to specify wind: speed and direction.
Which property of the air is the most responsible for the formation of convection currents?
Convection currents are formed in the atmosphere when cold air pushes warm air upward. Which property of the air is MOST responsible for the formation of convection currents? Density differences. A student reads the following statement.
Where are temperature inversions most likely to occur?
Conditions that Most Likely Favor Temperature Inversions
- 25% or less cloud cover.
- Light and variable winds (especially below 3 mph)
- Dry soil surface.
- Low elevation areas such as valleys and basins where cool air can sink and collect – Inversions will begin sooner, last longer, and be more intense in these areas.
What causes a temperature inversion?
If the air mass sinks low enough, the air at higher altitudes becomes warmer than at lower altitudes, producing a temperature inversion. … A frontal inversion occurs when a cold air mass undercuts a warm air mass and lifts it aloft; the front between the two air masses then has warm air above and cold air below.
Which of the following does not occur during a temperature inversion?
Q. Which of the following does not occur during a temperature inversion? Cool air at the Earth’s surface cannot move upward.
Why are urban areas prone to thermal inversion?
This happens because the warmer air layer sits over a city and prevents the normal mixing of cooler, denser air. The air instead becomes still and, over time, the lack of mixing causes pollutants to become trapped under the inversion, developing significant amounts of smog.
Why does temperature inversion occur in the stratosphere?
Ozone in turn is photolysed much more rapidly than molecular oxygen as it has a stronger absorption that occurs at longer wavelengths, where the solar emission is more intense. … The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion.
Which layers of the atmosphere do the major temperature inversions occur?
The stratosphere is characterized by a strong temperature inversion, as shown by the above figure. This is a stable layer with little mixing. As a result, pollutants and other particles may reside in the stratosphere for many years.
