1. synthesize what
three processes form the
biogeochemical cycle?

here is the answer

water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. 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.

i'm thinking 600 feet deep in one of the finger lakes.
