1

What are tectonic plates

ting Tectonic plates are floating on the semi molten layer of rock in the magma. Convection currents within the mantle cause the plates to move

2

Destructive plate boundary

When two plates move towards each other one sinks ( is subducted) below the other one. Volcanoes and earthquake are found here

3

How do plates move

1. This causes the tectonic plates to move constantly - either towards or away from one another
2.heat from the core causes convection currents in the mantle where the heated rock rises towards the crust
3. The mantle is a semi - molten layer of rock on which the tectonic plates are floating

Some counties are more developed
•buildings are more strong
•emergency services are better
•earlier warning systems and drills
