Because of extreme heat and pressure, the characteristics of rocks change the deeper underground they are.

• True

• False

The rock deep below the ocean bottom (basalt) is less dense than the rock deep below the continents (granite) because in molecules in basalt are more spread out.

• True

• False

Temperature increases and rocks are more compressed as

• we move up into the air.
