The video explains the geological processes that cause the movement of Earth's crust. Hot rock rises from the Earth's core, spreads, and cools, causing the crust to slowly drag apart, leading to continental drift. When tectonic plates collide, carbon-rich rock from the sea floor is subducted, melts, and releases carbon dioxide back into the atmosphere during volcanic eruptions, completing the carbon cycle.

What causes the hot rock to rise towards the Earth's surface?

• The Earth's core heating the rock

• The Earth's magnetic field

• The gravitational pull of the moon

• The rotation of the Earth

What happens to the rock after it spreads near the surface?

• It forms new mountains

• It turns into liquid magma

• It cools down and sinks back
