consists of solid material that has been deposited on Earths surface by wind, water, ice, gravity or chemical precip.

Physical weathering changes the composition is mineral fragments.

Occurs when very hot water reacts with rock

In the laboratory, rocks must be heated from 8000 C to 12000 C before they melt.

__________ has the highest silica content.
