b

c
Any small-scale event such as rain or fog

d
A process that changes the composition of rocks, causing them to break down

D

Explanation:

all the other choices represent something physically done, and D is the only one where something happens in the rock itself (chemically)

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
