Geomorphic Processes Questions

Multiple choice geography external forces - responsible for changes the soil soil erosion (geo) soil erosion, soil conservation and uses of soil

Soil conservation is the process where _____________.

  1. Sterile soil is converted to fertile soil

  2. Soil is aerated

  3. Soil erosion is allowed

  4. Soil is protected against loss

D Correct answer
Explanation

Soil conservation is a method of protecting soil from getting eroded either by wind or by water.

  • Few soil conservation methods include:
  • Graduated terrace steps which are commonly used to farm on hilly or mountainous terrain. Terraced fields decrease both erosion and surface runoff.
  • Wind breaks: Row of trees or a fence, wall, or screen that provides shelter or protection of soil from the wind.
  • Conservation tillage is a method of preparing soil from getting eroded. This technique involves leaving the previous year crop residues until the next crop is planted.

The land developed due to soil erosion is called as __________.

  1. Fallow land

  2. Bad land

  3. Waste land

  4. Culturable waste land
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The running water cuts through the clayey soils and makes deep channels as gullies. The land becomes unfit for cultivation and is known as bad land. In the Chambal basin such lands are called ravines.

Which of the following land forms is not associated with river erosion?

  1. Waterfall

  2. V-shaped valley

  3. Moraines

  4. Ox-bow lake
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Moraines is any glacially formed accumulation of unconsolidated glacial debris that occus in both currently and formerly glaciated regions on the earth. These are formed of the debris of glaciers. They are not formed due to river erosions.

Which of the following is/are responsible for riverbed and riverbank erosion?

  1. Flow of water

  2. Sand particles

  3. Pebbles

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The riverbed and the river banks get eroded because of the fast flow of water, sand particles, pebbles etc, and the various tributaries joining the main river. All these lead to the formation of gorges, V-shaped valleys and waterfalls.

What are the factor responsible for erosional transportational and depositional work?

  1. Slope of land

  2. Volume of water flowing in the river

  3. Volume of sediments in the river

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Following are the factor responsible for erosional transportational and depositional work of a river:-

  • Slope of land
  • The type of rock
  • Volume of water flowing in the river
  • The length of flow
  • Volume of sediments in the river

Which of the following is/are the type of moraines?

  1. Ground Moraines

  2. Lateral Moraines

  3. Medial Moraines

  4. Terminal Moranies

  5. All of above
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Depending on the location of the deposits, moraines can be divided into four type which are as follow:-

  • Ground Moraines
  • Lateral Moraines
  • Medial Moraines
  • Terminal Moranies

 Erosion caused by wind lead to formation of ______________.

  1. Mushroom rocks

  2. Deflation hollows

  3. Yardangs

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wind carries small sand particles, small pebbles, etc. along with it. These particles cause erosion along rocks coming in the way due to friction. This leads to formation of mushroom rocks, deflation hollows, yardangs, etc.
