Tectonic Plates
Geography: KS3, topic 11.1.3
Tectonic Plates
The Earth's crust is broken into large pieces called tectonic plates. There are two kinds of tectonic plates:
Continental plates
- Continental plates are thicker, older and lighter, so they do not sink (subduct).
Oceanic plates
- Oceanic plates are thinner, younger, and denser so they can sink (subduct) under another plate.
Plate margin (boundary)
- Plate boundaries and plate margins are the same thing.
- They describe the location on Earth where 2 tectonic plates meet or sit next to each other.
