What are plates?
Areas of earth between the sea.
Countries and continents.
Slabs of rock under the earth and sea.
Presentation: Tectonic Plate Motions 22/34
How fast are the plates moving?
A metre per day.
A few centimetres per day.

The sun
The Earth's crust
Nuclear power
Presentation: Tectonic Plate Motions 24/34
Presentation: Tectonic Plate Motions 25/34
Earth’s plates move due to a convection cell in…
the Earth’s crust
the Earth’s mantle
the Earth's inner core
the Earth's outer core
Presentation: Tectonic Plate Motions 27/34

True
False
Presentation: Tectonic Plate Motions 28/34
What happens at the ridges?
The material continues to cool and then sinks back down into the mantle at adeep sea trench.
The material gets hotter and then sinks back down into the mantle at a deep seatrench.
The material stays at the top and forms mountains.
