The Earth is like a ... ?

• Solid ball - the same all the way through

• Easter egg - hollow on the inside

• Giant peach - thin skin, core at the centre and soft flesh in between

• Nerf ball - soft all the way through

At the centre of the Earth is a place of extreme temperature and pressure. What is it called?

• Core

• Mantle

• Crust

Most of the Earth's interior is so hot that rocks melt and move slowly in giant currents. What is it called?

• Core

• Mantle

• Crust

The outside of the Earth is broken into large slabs called plates. The movement of these plates builds mountains and valleys. What is it called?

• Core

• Mantle

• Crust

How thick are the Tectonic plates which make up the Earth's outer surface?

• Around 1 kilometre

• Around 10 kilometres

• Around 100 kilometres

• Around 1000 kilometres

What is the molten rock in the interior of the Earth (under the tectonic plates called?

• Magnum

• Spagnum

• Magma

• Lava

Tectonic plates move due to the convection currents in the molten material under them. What causes these currents to occur?

• The heat from the Earth's interior

• The rotation of the Earth on it's axis

• The revolution of the Earth around the sun

• The forces of the ocean tides moving across the surface of the tectonic plates

In some places Tectonic plates are being pushed together. What is this called?

• Divergent boundary

• Transform boundary

• Converging boundary

In some places Tectonic plates are being pulled apart. What is this called?

• Diverging boundary

• Transform boundary

• Converging boundary

In some places Tectonic plates slide against one another. What is this called?

• Diverging boundary

• Transform boundary

• Converging boundary
