The process by which rocks are broken down in situ by chemical reactions involving oxygen, water, and carbon dioxide without movement of materials is called:

💡 Solution & Explanation

Chemical weathering refers to the in-situ decomposition and disintegration of rocks driven by chemical interactions with atmospheric gases and moisture, such as oxidation and carbonation, without physical displacement. In contrast, mass wasting and erosion involve the physical transport of debris across landscapes. Geomorphological processes and weathering types are fundamental concepts in physical geography.
