Film summary
From volcanic eruptions to massive earthquakes to tidal waves, Earth's tectonic plates can be responsible for catastrophic natural disasters.Key facts
- The rising and falling of intense heat deep inside the earth creates convection currents.
- Tectonic plates can be pulled apart, pushed together or forced to slide past each other by convection currents.
- The movement of plates causes earthquakes, volcanoes and tidal waves.
- The movement of tectonic plates can be constructive, destructive or conservative.
Transcript
Although the Earth's surface may seem very static, it's actually moving.
The rising and falling of heat deep inside the Earth causes convection currents.
Convection Currents
These can drag the plates apart, causing them to travel a few centimeters every year.
This might not seem much, but the effects are dramatic.
It's what causes earthquakes, …
