Question

Quizplus · Accepted Answer

Water is the single most important weathering agent as it can both physically and chemically weather rocks and minerals. It can freeze and expand, causing mechanical weathering, and it can dissolve minerals and facilitate chemical weathering. Carbon dioxide, oxygen, and nitrogen can also contribute to weathering, but they are not as significant as water. Water vapor plays a role in the formation of moisture, but it is not a weathering agent itself.
