Detailed explanation-1: -Water, and many chemical compounds found in water, is the main agent of chemical weathering.

Detailed explanation-2: -In weathering, when oxygen combines with another substances, oxidation has occurred. Sometimes a change in the color of a rock is an indication that oxidation has occurred. One common example of oxidation rust.

Detailed explanation-3: -Types of Chemical Weathering. Several factors cause chemical weathering. These factors include water, oxygen, acids, carbon dioxide, and organisms that are living on Earth. These factors cause elements to break down and dissolve or create new materials.

Detailed explanation-4: -Oxygen, surface and/or soil water and other acids are the agents of chemical weathering.

Detailed explanation-5: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
