We know that the Earth's crust is composed of plates. There is also evidence that these plates move. But how? Some of these statements correctly describe the mechanisms behind plate movement.

Can you identify the statements that correctly describe the movement of tectonic plates on Earth?

Earth's interior is heated by radioactive decay of elements such as uranium, thorium, and potassium.

The Earth's iron-nickel core generates electricity, which in turn generates heat.

Under Earth's crust is a malleable layer of heated rock known as the asthenosphere

Magma continuously wells upwards at the mid-oceanic ridges producing currents of magma flowing in opposite directions.

When tectonic plates meet they always crumple and fold stopping the movement and create mountains.

The asthenosphere circulates as convection currents underneath the solid lithosphere.
