Answer: a. They continuously recycle Earth's materials.

b. They contribute to a balance or equilibrium of Earth's materials.

Earth's hydrologic cycle involves the cycling of water. A natural replenishment process of water. Rock and tectonic cycles causes replenishment of rocks and geospheres. These cycles allows the generation of new materials. They contribute to a balance or equilibrium of Earth's material, for example magma release from earth crust during volcanic eruptions can destroy all nearby and superficial rocks, but when the magma solidifies to form new rocks. Therefore, materials which are destroyed are again created hence, equilibrium remains maintained.
