4) A : Surface water helps solifluction
R : Water table is responsible for the same.
Answers
Explanation:
A The main uses of surface water include drinking-water and other public uses, irrigation uses, and for use by the thermoelectric-power industry to cool electricity-generating equipment.
B dont know
Answer:
The above given reason is not the correct explanation of the assertion
Explanation:
Solifluction is defined as the downward movement of soil along a steep slope that are fully saturated. In the arctic region, there is the presence of permafrost layer which is impermeable to the water and the soil that is present over this layer becomes saturated and flows downslope due to the action of gravity. The average movement of these soil materials is about a few inches each day. Solifluction results in a slope that is very smooth and gentle, in nature and the surface water favors this process to take place. Thus, it can be considered as a type of mass wasting process.
On the other hand, water table is defined as the layer of water that flows below the earth's surface and it separates the zone of aeration and the zone of saturation.
The process of solifluction occurs on the surface of the earth, whereas the water table is present below the earth's surface. So, the water table is not responsible for the process of solifluction.
