frost wedging

tree root wedging

The amount of dry weather and frost wedging.

The type of rock and the climate.

The age of the rock and the current weather.

repeated process that splits rock when water seeps into the cracks, then freezes and expands, causing pieces to break off

scratching, scraping, or grinding of rock by other rock particles carried in water, ice, or wind

the cracks widen as roots grow thicker

rocks expand when heated and contract when cooled

carbonation

chemical weathering

Rust decomposes rocks completely with the passage of time.

Some of the minerals get dissolved in water.

The joints enlarge in size and lime is removed in the solution.

Due to the absorption of water by rocks, its volume increases.
