Processes of Chemical Weathering - CliffsNotes

Processes of Chemical Weathering. When a rock is brought to the surface millions or billions of years after it has formed, the original minerals that were crystallized deep in the crust under high pressures and temperatures are unstable in the surface environment and eventually break down. The primary agents in chemical weathering are water ...
