Which of the following is/are methods of checking soil erosion?
$1$. Strip cropping
$2$. Contour ploughing
$3$. Use of irrigation and fertilisers
$4$. Terrace farming.

  1. $1$ and $2$
  2. $3$ and $4$
  3. $2, 3$ and $4$
  4. $1, 2, $ and $4$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing. 
  • Steps can be cut out on the slopes making terraces. Terrace cultivation restricts erosion. 
  • Large fields can be divided into strips. Strips of grass are left to grow between the crops. This breaks up the force of the wind. This method is known as strip cropping. Strip cropping method reduce the soil erosion

  2. II, III and IV

  3. II and IV

  4. I and III

A Correct answer
Explanation

Contour ploughing, terracing, and crop rotation are all effective soil conservation techniques. Shifting cultivation is generally considered harmful to soil as it involves clearing and burning land.

Which of the weathering agents is almost peculiar to the Indian Himalayas?

  1. Wind

  2. Glaciers

  3. Snowfall

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

A glacier erodes through a process called ‘plucking’ in which it lifts pieces of rock and transports them. These pieces of rock and the moving ice together act like a sandpaper on the surface of the rock over which they flow. In the Himalayan region, the glacier is the major weathering agent.

Which one of the following types of erosion is responsible for the formation of Chambal Ravines?

  1. Splash

  2. Sheet

  3. Rill

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

Gully erosion occurs when water flows in narrow channels during heavy rain, cutting deep trenches into the soil. This process is responsible for the formation of the extensive Chambal Ravines.

  2. Black soils are rich in phosphorus nitrogen and organic matter

  3. Alluvial soils are rich in potash but poor in phosphorus

  4. Red soils are suitable for cultivation of pulses and coarse grains

  3. West Bengal

  4. Tamil Nadu
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Coastal erosion is a significant issue in many Indian states, but Kerala is widely cited in geographical studies for its severe and persistent coastal erosion problems due to its specific coastline characteristics and high population density along the shore. While other states also face erosion, Kerala's situation is often highlighted as particularly critical.

Ravines is a common term used in Chambal valley for __________.

  1. Sheet erosion

  2. Gully erosion

  3. Wind erosion

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

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