Below the lithosphere is the asthenosphere — a viscous layer kept malleable by heat deep within the Earth. It lubricates the undersides of Earth's tectonic plates, allowing the lithosphere to move.

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

Ask students what layer of the Earth is shown through ... in other places it exposes the white part of the egg). This is how Earth's tectonic plates move. This results in formations of mountains ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...

The movement of these tectonic plates leads to earthquakes and ... in the centre of the Earth, and is the hottest layer. It is spherical and solid and made up of iron and nickel.
