Lesson Details
Key learning points
- Earth is composed of four layers: the crust, mantle, outer core and inner core.
- Movement in the tectonic plates that form Earth’s crust causes earthquakes.
- Earthquakes occur at plate boundaries.
Common misconception
Earthquakes are random events.
Earthquakes are not random events, but are a consequence of tectonic plate movement.
Keywords
Earth’s crust - Earth’s crust is the outermost layer of our planet.
Tectonic plates - The huge pieces that Earth’s crust is broken into are known as tectonic plates.
Shock waves - Shock waves are areas of sudden high pressure or temperature that travel through water, air or the ground.
Plate boundaries - The point where two tectonic plates meet is known as a plate boundary.
