The structure of the Earth

Geography

This unit teaches pupils about tectonic hazards, their location, causes and effects. Pupils learn about the different types of hazard before focusing on earthquakes and volcanoes. Pupils will learn about tectonic processes, hazard impacts and the options for mitigation and adaptation.

Tectonic hazards

Earth has a layered structure, put it in order from the surface to the centre ...

Match the layer to its correct physical state.

denser materials (iron and nickel) sank to form the core

lighter materials (like silicates) rose to form the mantle and crust

when the crust is melted at plate margins, denser materials

from the crust sink and lighter materials rise to form new crust.

Why is the crust's composition different from the mantle's?

silicates (mainly oxygen, silicon, aluminium)

silicates (oxygen, silicon, magnesium, iron)

Match the layers to their correct composition:

Which of the following is **not** part of Earth's structure?

Match the layer of Earth with its correct physical state.

The inner {{}} of Earth is responsible for most of the planet's internal heat.
