The process of which freeze-thaw or physical weathering takes place is rather simple.
Firstly, water would get into cracks on a rock or hard material, and overnight, it would freeze.
Secondly, because when water freezes, it expands, it therefore forces itself further into the rock; the crack is made larger.
Lastly, this would created more space inside the rock, for more water to end up inside, and join in with the freeze-thaw, until finally, the rock would break.
It is an example of mechanical or more specifically biomechanical weathering.
This is an example of chemical weathering, as the acid rain is reacting chemically with the minerals in the rocks to break them down.
Subjection to extreme temperatures is an example of physical weathering, where rocks are broken down into smaller pieces due to repeated heating and cooling cycles. This process is known as thermal stress weathering.
Subjection to extreme temperatures is an example of physical weathering, specifically known as thermal weathering. This process involves the expansion and contraction of materials due to repeated heating and cooling, which can lead to the breakdown of rocks and minerals.
Which of the following is an example of chemical weathering?
A type of Chemical weathering that happens when water interacts with minerals.
Mechanical Weathering

Physical weathering is a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition.
Physical Weathering (aka Mechanical Weathering) is the main type of weathering in deserts.

Which of the following is an example of chemical weathering?
Chemical weathering causes acid rain. When sulfur dioxide and nitrogen oxides are released into the atmosphere from human activities, they combine with water vapor to form sulfuric acid and nitric acid, which then fall to the earth's surface as acid rain.
