Wind, water, and freezing all cause rocks to erode or weather.
Chemical weathering is the type of weathering that causes the mineral composition of rocks to change. This process occurs when minerals in rocks react with elements in the environment, causing a chemical reaction that alters the rock's mineral composition over time.
Thermal weathering occurs when rocks are exposed to extreme temperature changes, such as those from forest fires. The rapid heating and cooling of rocks causes them to expand and contract, eventually leading to the splitting and fracturing of the rocks.
When rocks undergo weathering, they can form sedimentary rocks. Weathering breaks down rocks into smaller sediments, which then get compacted and cemented together to form sedimentary rocks.
Frost action is a type of mechanical weathering. It occurs when water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart.
It is a form of weathering known as frost wedging.

Physical weathering.
chemical weathering
Plants can cause mechanical weathering by growing into cracks in rocks and breaking them apart as their roots expand. They can also cause chemical weathering by releasing acids and other compounds that break down the minerals in rocks.
The type of chemical weathering that breaks down rocks is acid.
Chemical Weathering
Thermal weathering occurs when rocks are exposed to extreme temperature changes, such as those from forest fires. The rapid heating and cooling of rocks causes them to expand and contract, eventually leading to the splitting and fracturing of the rocks.
Thermal expansion causes repeated expansion and contraction within the rock. This repeated stress breaks bonds and eventually causes the rock to crack. Thermal expansion is classified as a type of physical or mechanical weathering.

Frost action is a type of mechanical weathering. It occurs when water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart.
Root wedging is caused by physical weathering, where plant roots grow into cracks in rocks and exert pressure as they expand, gradually breaking the rock apart.
