Geomorphic Processes

2,085 Questions

Geomorphic processes shape the Earth surface through physical mechanisms like weathering, erosion, and deposition. This topic covers soil formation, glacial movement, and coastal landform development. It forms a core component of physical geography in major competitive examinations.

Geomorphic Processes Questions

Multiple choice

Deep gullies and ravines formed by soil erosion by water is a characteristic of

  1. Kosi valley

  2. Chambal valley

  3. Mahanadi valley

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

The Chambal valley is famous for its deep gullies and ravines known as 'badlands,' formed by extensive soil erosion. The region's highly erodible soil combined with seasonal torrential rains creates this characteristic landscape. Kosi, Mahanadi, and Narmada valleys have different erosion patterns and are not known for such extensive gully formation.

Multiple choice

Sheet erosion over earth surface is caused with the action of

  1. strong winds

  2. moving ice

  3. shifting cultivation

  4. heavy rains
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sheet erosion occurs when heavy rainfall creates water runoff that removes thin, uniform layers of topsoil across the land surface. Unlike wind or ice erosion, this water-based process affects broad areas evenly.

Multiple choice

Which of the following is/are methods of checking soil erosion?

  1. Strip cropping
  2. Contour ploughing
  3. Use of irrigation and fertilizers
  4. Terrace farming

  1. 1 and 2

  2. 1, 2, 3 and 4

  3. 3 and 4

  4. 2, 3 and 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

All four methods help control soil erosion: strip cropping (alternating crops to break water flow), contour ploughing (ploughing across slopes), irrigation/fertilizers (maintaining vegetation cover), and terrace farming (reducing slope steepness). Option A is incomplete, while options C and D omit key methods.

Multiple choice

Match the following:

 
a. Physical weathering 1. It involves a variety of processes such as hydrolysis, hydration, oxidation and reduction.
b. Chemical weathering 2. It is done by living organisms such as lichens and bryophytes.
c. Biological weathering 3. It involves various climatic factors such as temperature, wind, rain water, ice, snow, glaciers and running water.

  1. a - 3, b - 2, c - 1

  2. a - 3, b - 1, c - 2

  3. a - 1, b - 3, c - 2

  4. a - 1, b - 2, c - 3

  5. a - 2, b - 1, c - 3
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is the correct option. a. Physical weathering - 3. It involves various climatic factors such as temperature, wind, rain water, ice, snow, glaciers and running water. b. Chemical weathering - 1. It involves a variety of processes such as hydrolysis, hydration, oxidation and reduction. c. Biological weathering - 2. It is done by living organisms such as lichens and bryophytes.  

Multiple choice

Which of the following processes is responsible for producing the sand dunes in western Rajasthan?

  1. Wind erosion

  2. Erosion by water

  3. Wind deposition

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

Wind deposition creates sand dunes when wind carries sand particles and deposits them in piles. Wind erosion removes material but does not build up dunes. Water erosion and mechanical weathering are not responsible for dune formation in arid regions like Rajasthan.

Multiple choice

Which of the following landforms are not caused due to running water?

  1. Gorges

  2. Canyons

  3. Valleys

  4. Tunnels
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gorges, canyons, and valleys are classic landforms carved by running water (rivers) over millions of years through erosion. Tunnels, however, are typically artificial structures built by humans for transportation (railways, roads) or water management, though natural caves can form through other processes like chemical weathering in limestone.
