Both physical and chemical weathering break down rocks by weakening their structure. Physical weathering involves the mechanical breakdown of rocks into smaller pieces, while chemical weathering involves the alteration of the rock's composition through chemical reactions. Over time, these processes can cause rocks to crumble, crack, and eventually disintegrate.
Physical weathering breaks down rocks into smaller pieces, increasing their surface area exposed to chemical weathering processes. Chemical weathering alters the mineral composition of rocks, weakening them and making them more susceptible to further physical weathering. Together, physical and chemical weathering work to break down rocks into smaller particles and alter their composition over time.
An example of Physical Weathering is plant wedging, where a plant finds its way into a rock and its roots wedge the rock apart. An example of Chemical Weathering is Acid Rain, where chemicals in the clouds caused by global warming rain down and dissolve rocks. Thousands of years of acid rain can result in discoloring and the breaking down of rocks.
Chemical weathering can weaken rocks by altering their composition, making them more susceptible to mechanical weathering processes such as frost wedging or root growth. This can lead to the breakdown of rock into smaller fragments through physical forces.
Physical weathering physically breaks down the rock, whereas chemical weathering breaks down the rock through chemical changes. For example, physical weathering could break down rock through ice wedging, which occurs when water seeps through the cracks in the rock, freezes, and expands, causing the rock to crack. Chemical weathering could be when oxidation (rusting) occurs, when metal is exposed to water and oxygen. Either way they both break down rock.

mechanical weathering and chemical weathering are related because their both are types of weathering
One way in which Earth's atmosphere interacts with the geosphere is through weathering processes. Weathering, such as chemical and physical breakdown of rock surfaces, occurs through interactions with the atmosphere's elements like oxygen and water. This weathering can lead to the breakdown of rocks into sediments which can then be transported and deposited in different areas.
physical weathering
Acids in the rain create holes in the rock, which allows water to get inside for ice wedging.
It is a physical change.
Evaporation is an example of a physical change, as the chemical composition of the substance is not altered in any way.
