Answer:
D.The temperature of the water increases.
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.
