Structure of the Earth

Crust = solid outermost layer

Mantle = middle layer

Core = inner layer outer core = liquidinner core = solid

Why do we have continental drift?Internal Heat Drives Geological Activity

Convection: hot rock rises, cool rock falls.

Why do we have continental drift?

Earth has molten centerConvection current form in mantleThe crust moves with these currents

Internal Heat Drives Geological Activity

Convection: hot rock rises, cool rock falls& the solid surface of the Earth moves
