Question

Quizplus · Accepted Answer

Liquid water is the single most important weathering agent because it plays a crucial role in both mechanical and chemical weathering processes. Water can break down rocks through physical forces such as freeze-thaw cycles and erosion, as well as chemical reactions such as dissolution and hydrolysis. Without liquid water, most forms of weathering would be greatly reduced.
