Detailed explanation-1: -Rainwater also mixes with chemicals as it falls from the sky, forming an acidic concoction that dissolves rock. For example, acid rain dissolves limestone to form karst, a type of terrain filled with fissures, underground streams, and caves like the cenotes of Mexico’s Yucatán Peninsula.

Detailed explanation-2: -Chemical weathering describes the process of chemicals in rainwater making changes to the minerals in a rock. Carbon dioxide from the air is dissolved in rainwater, making it slightly acidic. A reaction can occur when the rainwater comes into contact with minerals in the rock, causing weathering.

Detailed explanation-3: -Weathering breaks things down into smaller pieces. The movement of pieces of rock or soil to new locations is called erosion. Weathering and erosion can cause changes to the shape, size, and texture of different landforms (such as mountains, riverbeds, beaches, etc).

Detailed explanation-4: -When rocks are weathered, they break down into loose rock and mineral grains, which are then carried away by erosion processes. These sediments are transported by water, wind, or gravity, and are eventually deposited in various sedimentary environments.

Detailed explanation-5: -Erosion is one that most everyone is familiar with. This is the removal of sediment such as sand, silt or gravel, by wind or water. Weathering is the breaking down of rock material by things like heating and cooling, frost or crystal wedging, or chemicals, like acid in rain.
