Question

Which of the following about saltation is not true?

(a) In this process the heavier and coarse sediments are lifted up

(b) They are lifted up periodically and for short distances

(c) In this process the light-density particles are carried away

(d) It is the process of sediment transport by series of jump

I had been asked this question in final exam.

Question is taken from Geological Work of Wind in division Geological Work of Natural Resources of Engineering Geology

Answer 1

Right answer is (c) In this process the light-density particles are carried away

Easy explanation: The heavier and coarse sediments such as sand grains, pebbles and gravels etc. are lifted up periodically during high velocity times and only for short distances and that too for smaller heights above the ground. The uplifting of lighter particles is called suspension.
