Geomorphic Processes Questions

Multiple choice

What is a jet stream?

  1. The thrust produced by jet engines of plied to the engines of and aircraft.

  2. The tubes through which fuel is supplied to the engines of an aircraft.

  3. An invisible river of rushing wind above the clouds streaming round the earth.

  4. White trail of smoke left behind by an aircraft when flying at high altitude.

C Correct answer
Explanation

Jet streams are narrow bands of strong winds flowing in the upper atmosphere, typically 6-9 miles above Earth's surface. They form due to temperature differences between air masses and influence weather patterns globally.

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.
