Other than the rock itself,which is the most important chemical substance needed for the majority of weathering processes?

Question

Quizplus · Accepted Answer

Water is essential for most weathering processes, including physical and chemical weathering. It enables chemical reactions and can contribute to the breakdown of rocks through freeze-thaw cycles, hydration, and dissolution. Without water, most weathering processes would be significantly slowed or halted altogether. While oxygen, nitrogen, and carbon dioxide can all play a role in specific types of weathering, water is the most universally important substance in weathering processes.
