Question

Which of the following landforms are formed by wind deposition?

A. Inselberg
B. Zeugen
C. Mushroom rock
D. Yardangs

Choose the correct answer from the options given below:

1. Only two are correct
2. Only three are correct
3. All the above are correct
4. None of the above are correct

Answer 1

Correct Answer: None of the above are correct

---

Explanation:

The given landforms—inselberg, zeugen, mushroom rock, and yardangs—are not formed by wind deposition. Instead, they are landforms associated with wind erosion or other geological processes.

1. Inselberg:

   • These are isolated hills or rock outcrops rising abruptly from flat surrounding areas.
   • Formed by erosion of surrounding material rather than wind deposition.

2. Zeugen:

   • These are tabular masses of rock formed by wind erosion, where softer layers are eroded faster than harder layers above.

3. Mushroom rock:

   • These are rock formations shaped like mushrooms, created by abrasion due to wind erosion, with the base eroded faster than the top.

4. Yardangs:

   • These are streamlined ridges formed by wind erosion, aligned in the direction of prevailing winds.

Conclusion:

None of the given landforms are created by wind deposition. They are all primarily the result of wind erosion.
Thus, the correct answer is None of the above are correct.
