What is the FOCUS of an earthquake?
The point beneath the earth's surface where rock breaks under stress and triggers an earthquake
400
How are metamorphic rocks formed?
From heat and pressure
400
When a rock is weathered, what happens to it?

What happens when a rock is chemically weathered?
Chemical weathering changes the composition of the rock.
