• elevation

• composition and texture

• the pressure at which they formed

What is the chemical makeup, or mineral content, of a rock based on?

• its composition

• the size of its grains

• the positions of its grains

• the shape of its grains

What factors can affect the texture of an igneous rock?

• the size of the rock

• the minerals that cement the rock together

• the length of time the magma had to cool

• the pressure and temperature the rock was exposed to
