What is the role of swash and backwash in longshore drift?
Answer and explanation
Correct answer: तिरछा स्वैश कणों को तट पर आगे ले जाता है और बैकवॉश उन्हें ढाल के अनुसार लौटाता है
The governing concept is longshore drift, the net movement of beach sediment along a coast. When waves approach obliquely, swash carries sand and shingle up the beach at an angle. Gravity then makes the backwash flow downslope, usually more directly seaward, so repeated movements create a zigzag path with a net alongshore transfer. Glaciers, karst caves, and river potholes are unrelated; therefore option A is correct.
