Soil can be conserved in a best on the hills by which of the cultivating methods?

  1. Strip cropping

  2. Crop rotation

  3. Contour ploughing

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

Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing. This is the best method to reduce the soil erosion in the hilly areas.

D Correct answer
Explanation

Khadar, Bangar, and Bhabar are all types of alluvial soils classified by their age and location in river plains. Regur (Black soil) is formed from volcanic rock, making its formation process distinct.

$2$. Terracing
$3$. Shifting cultivation
$4$. Crop rotation.

  1. I, II and IV

  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.
