1  a. Precipitation

2 b. biochemical cycling

3 c. gravity

Explanation:

Precipitation is any product of the condensation of atmospheric water vapour that falls under gravity.

Biochemical cycling, cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) parts of Earth.
