Weathering is which type of process on the Earth's surface?

Correct answer: Exogenic process

Correct answer: B, an exogenic process. Geomorphic processes are commonly grouped into endogenic and exogenic processes. Endogenic processes originate inside the Earth and include forces associated with internal heat, tectonic movement, and volcanism. Exogenic processes operate at or near the surface and are driven by agents such as water, wind, ice, temperature change, and organisms. Weathering breaks down or alters rock in place at the surface, so it belongs to the exogenic group. A is wrong because endogenic processes arise within the Earth. C is not the standard geomorphic classification for weathering. D is too narrow and refers to volcanic activity, which is generally linked with internal Earth processes, not ordinary surface weathering. Remember: “exo” means outside; surface processes are exogenic.
