Layers of the Earth

We discussed the various layers of the Earth last lesson. 

Let's review them!

The inner core is solid because the

2. pressure is low
3. temperature is low
4. pressure is high

Magma, which causes the plates to move, is found in the

1. outer mantle
2. inner core
3. inner mantle
4. outer core

The radius of the Earth is

1. 12800 km
2. 640 km
3. 6400 km
4. 1280 km

1. The hot molten rock on which the plates float is called magma

2. The plates move as fast as the growth of your finger nails.

3. When one of the plates is forced downwards it is called subduction.

4. When two plates crumble during collision this is called uplift.

5. The Himalayas were formed as a result of this collision.

6. When tectonic plates collide sideways this is called transform movement.

7. Along fault lines earthquakes may occur.

8. The hypocentre is where the earthquake starts.
