Answer:
D. Wind, rain, and ice.
Step-by-step explanation:
The term weathering comes from the process of rocks or other surfaces being broken down after being exposed to the elements. This refers to elements such as wind, rain, and ice. All of these things can slowly break down anything left outside or exposed to the weather. The other answers are incorrect because weathering only refers to the processes created by the atmosphere. Things like erosion, time of day, and volcanoes are unrelated to the atmosphere and therefore not weathering.
