How can water cause weathering?

1 answer

Water can cause weathering in several ways:

1. Mechanical weathering: Water can penetrate cracks in rocks and then freeze and expand, causing the rock to break apart. This process is known as frost wedging.

2. Chemical weathering: Water can react with minerals in rocks, causing them to dissolve or weaken. For example, water can react with minerals like feldspar and produce clay minerals, which can lead to the disintegration of the rock.

3. Erosion: Water can carry sediment and rocks, wearing away at the surface of rocks over time. This process, known as erosion, can lead to the breakdown and transport of rock material.

Overall, water can contribute to weathering by physically breaking down rocks through mechanical processes, as well as chemically reacting with minerals in rocks to weaken and dissolve them.
