3 ways water can weather rock?

Answer 1

They can be weathered:

1. mechanically/physically:- such as freeze-thaw (where the rock has a joint or crack in which water is filled (by rain or other forms of precipitation) is frozen due to cold climate making the water turn to ice, therefore expanding causing the rock to expand, and over time this causes the rock to crumple into scree) and onion peel (where the outer layers of the rock flake of due to the sudden difference of temperatures causes the expanding and contracting the form cracks)
2. chemical weathering:- when acid rain (H20 + CO2) weathers rocks such as limestone forming joints and cracks
3. Biological weathering:- weathering due to natural causes such as rabbits and tree roots in which speeds up physical weathering, due to the fact that rabbits causes rocks to crumble when making burrows and tree rocks increases the width of the joints by roots growing through and around.

Answer 2

Water can weather rock through abrasion, where sediment carried by water scours and wears down the rock surface. It can also weather rock through dissolution, where water chemically breaks down minerals in the rock. Freeze-thaw weathering occurs when water enters cracks in the rock, freezes, expands, and then thaws, causing the rock to break apart.

Answer 3

through freeze-thaw cycles

through hydration

through erosion
