Inner metallic core - solid and the outer core - liquid
2 of 8
Types of tectonic plates.
Continental and oceanic.
3 of 8
What's a plate margin?
The meeting of two tectonic plates.
4 of 8
Characteristics of continental plates vs oceanic plates.
Continental playes are thicker, older and loghter, so they don't sink
5 of 8
What causes tectonic plates to move?
Convection currents that happen in the upper mantle.
6 of 8
Explain convection currents.
The core heats up the molted rock which then rises and hits the underside of the plate. The molten rock drags the tectonic plate that is on top of the mantle with it.
