The total amount of crustal material is steadily decreasing due to erosion.

It is part of a dynamic system that continuously recycles rock.

New crust is constantly formed, but old crust is never destroyed.

What are the two primary energy sources that drive the continuous transformation of Earth's surface materials?

Sunlight and Earth's internal heat

Gravitational pull from the Moon and radioactive decay in the crust

Magnetic fields and volcanic eruptions

It will become permanently fixed as part of the mountain peak.

It will be compressed into a denser form of metamorphic rock instantly.

It cools and solidifies into a fossil.

It is converted into water vapor.
