Question

asertion(A):terrace cultivation does not restrict erosion.
Reason(R):running water cuts through the clayey soil and makes deep chammel and gullies. this helps to cultivate crops.​

Answer 1

(d) Both assertion and reason are false

Explanation:

• Terrace cultivation is method of crop growing on sides of mountains/hills  by planting on graduated terraces that are built into the slope. Although labor-intensive, this method has been employed effectually to maximise arable land area in variable terrains and to decrease water loss and soil erosion.Terraces, out on slopes in forms of steps breaks up the force of  the  wind,  and therefore prevent erosion.  
• A gully is a form of land created by running water, eroding sharply into soil, usually on a hillside. Gullies resemble small valleys or large ditches. The  gullies render cultivation in those lands impossible
