| Crust | The Earth's outer skin, made of solid rock between 10km and 60km thick.

| Mantle | A layer of hot, soft rock in a molten of semi-molten state with temperatures of about 4000c.
🗑

| Core | Found at the centre of the Earth and made of nickel and iron, this is the hottest layer of the Earth, at over 5000c
🗑

| Magma | The molten or semi-molten material that makes up the Earth's mantle.
🗑
|

| Plates | The sections that the Earth's crust is broken into.
🗑

| Plate tectonics | The theory that attempts to explain the movement of plates and the features that result.
🗑
|
||||
| Convection currents | The movement of magma in a circular motion as it is heated by the core.
🗑
|
||||
| Transform boundary | Plates that slide past each other , neither creating or destroying crust.
🗑
|
||||
| Destructive boundary | Where plates collide causing crust to be destroyed as the heavier plate is forced down in to the mantle where it melts.
🗑
|
||||
| Constructive boundary | Where plates separate causing new crust to be created as magma rises to the surface cools and solidifies.
🗑
|
||||
| Continental drift | The process by which the plates drift on the mantle carrying the continents with them,
🗑
