C Correct answer
Explanation

Extensive loess deposits are found in northern China, the Great Plains of North America, central Europe, and parts of Russia and Kazakhstan. The thickest loess deposits are near the Missouri River in the U.S. state of Iowa and along the Yellow River in China.

The process which brings about a reduction in the difference in height between the high lands and the low lands is called ____________.

  1. Degradation

  2. Aggradation

  3. Gradation

  4. Weathering

C Correct answer
Explanation

Gradation is the process of leveling the land surface by the combined action of degradation (wearing down) and aggradation (building up).

Which sequence of processes occurs in the correct order?

  1. weathering, erosion, transportation

  2. erosion, weathering, transportation

  3. erosion, transportation, weathering

  4. All of these processes occur at the same time.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Weathering is the breakdown of rocks and materials attached to the earth's surface.
  • Erosion is the removal of material from their original place on earth's surface after it has been weathered.
  • Transportation is the movement of the eroded materials to long distances by the actions of various agents like water, wind etc.
  • Hence the sequence will be weathering, erosion and transportation

Glaciers are  ____________.

  1. A summer climate does not occur

  2. The temperature remains below freezing

  3. A solid mass of snow which moves downhill under the influence of gravity

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The moving ice mass downslope under the impact of gravity is called a glacier. About 10% of the earth's surface is now covered by the glacier. Glaciers are generally divided into two broad categories viz.

(i) mountain or valley glaciers and (ii) continental glaciers.

Weathering involves the ___________.

  1. picking up of rock fragments.

  2. movement of rock fragments.

  3. mechanical and chemical breakup of rocks.

  4. formation of rocks by the action of weather.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Weathering refers to the breakdown or disintegration and decomposition of rocks in situ through mechanical and chemical changes in the rocks. Weathering by itself is a static process and does not involve removal of the material. The products of weathering tend to accumulate in a soft surface layer.

Which of the following material is least susceptible to chemical weathering?

  1. Halite

  2. Quartz

  3. Limestone

  4. Feldspar
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Quartz is the second most abundant mineral in the earth’s crust. This is used in making jewelry and hard stone carvings. It is the hardest material and is least susceptible to chemical weathering.

Which one of the following is not the agents of weathering?

  1. Soil

  2. Glaciers

  3. Wind

  4. Rain water
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Glaciers, winds and rainwater are the agents of wethering which imply they are the forces that carry out the breakdown of materials over the earth's surface
  • Soil is the material which is formed as the result of wethering hence it is not the agent of wethering and this is the right answer.

In air, amount of water vapor is classified as ______________.

  1. wind

  2. precipitation

  3. humidity

  4. temperature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Evaporative cooling is restricted by atmospheric conditions. Humidity is the amount of water vapor in the air. The vapor content of air is measured with devices known as hygrometers. The measurements are usually expressed as specific humidity or percent relative humidity. The temperatures of the atmosphere and the water surface determine the equilibrium vapor pressure; 100% relative humidity occurs when the partial pressure of water vapor is equal to the equilibrium vapor pressure. This condition is often referred to as complete saturation.
