Question

Assertion [A]: The Shiwaliks in Punjab are highly prone to gully erosion from seasonal rivulets and has adverse ecological consequences.

Reason [R]: Intense rainfall in the region and the ecological degredation of Shiwaliks exposes the foothills to gully erosion from ephemeral streams.

Read the above given statements and select the option that is true.

• A. Both A and R are true. R is the incorrect explanation of A.
• B. Both A and R are true. R is the correct explanation of A.
• C. A is true but R is false.
• D. Both A and R are false.

Answer 1

The correct option is B Both A and R are true. R is the correct explanation of A.

The lower foothills of Shiwaliks in Punjab are severely exposed to gully erosion from epemeral streams and gullies. The gullies dissects the fields, impedes the tillage operations, damages agricultural, residential and recreational land resources. The Shiwaliks are a fragile ecosystem of the Himalayas. Ecological degradation in Shiwaliks is the outcome of continued over-exploitation, deforestation, over-grazing and clearance of land for agricultural purposes. The loss of vegetative cover in the Shiwaliks increases the ecological effects of gully erosion due to its proximity to the plains.
