- Plates move in a pattern called a convection currents that forms when warm material rises, cools, and eventually sink down.
- Tectonic plates move due to magma currents in the earth's mantle
- These are driven by the heat produced by the decay of radioactive elements and heat left over from the formation of the Earth.
- These currents slowly move the crust around.
- In some places the crust is destroyed and in other places new crust is formed.
Questions
- Why do tectonic plates move?
- What are convection currents?
