Temperature Change. Hot temperatures can give rise to thermal expansion in rocks and cool temperatures can cause rocks to contract.

Ans in brief-1) what are the main types of chemical weathering.

Thermal expansion is caused by heating. When rocks are heated -- as by the sun -- they expand. If different portions of a rock expand at different rates, the heated parts will exert pressure on each other, and crack. What Is Chemical Weathering.
