Earth is a very dynamic planet Earth is made up of different layers:

- Core - interior made up of dense, extremely hot metal, mostly iron. It is the most inside

layer of earth.

- Mantle - hot, pliable layer that surrounds the most inner layer, the core. It is less dense

than core.

- Crust - cool, lightweight, brittle, which floats on top of mantle. It is the outer layer of

earth.

Tectonic processes reshape continents and also cause earthquakes

- Tectonic plates- plates caused by convection currents in the mantle that causes

earthquakes.

- Ocean basins form where continents crack and pull apart.

- Magma – is molten rock
