A rock lies in a river bed in a warm and wet climate. Which factor would speed up its weathering?

A.

The rock is buried a few feet under the ground.

B.

The precipitation in the area decreases.

C.

The flow of the water slows down considerably.

D.

The temperature of the water increases.

D. The temperature of the water increases.

Step-by-step explanation:

Weathering is a term which describes the general process by which rocks are broken down at the Earth's surface into such things as sediments, clays, soils and substances that are dissolved in water.

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering.

More the temperature more will be the rate of Weathering so answer D is correct.
