Answer:
The velocity of the transporting agents is directly related to their depositional process. This means that the type of depositional features it forms depends upon the rate at which these agents namely the water, wind, and ice moves.
When water or wind flows over the surface of a rock at a speed up to 1 m/sec² carrying comparatively finer particles, after deposition it produces ripple marks and when it exceeds beyond 2 m/sec², it tends to form antidunes.
Again, when it carries larger particles with low transporting speed i.e. below 1 m/sec², it produces dunes and plane beds.
In the high elevated areas, the movement of ice is responsible for the formation of different types of depositional features that includes the moraines, Roche mountains, eskers as well as drumlins. The ice normally flows over the surface at a speed of nearly 10 to 15 inches each day.
