• Theory that states that the continents have moved apart over millions of years, causing the same animal and plant fossils to be found on different continents

1,4

Theory of Continental Drift

Theory that states that the continents have moved apart over millions of years, causing the same animal and plant

fossils to be found on different continents

Theory that states that the Earth’s lithosphere (crust and mantle) move on top of the

asthenosphere

2,4

The Theory of Plate Tectonics

Theory that states that the Earth’s lithosphere (crust and mantle) move on top of the asthenosphere

3,4

Pangaea

Wegener’s name for the giant land mass that existed millions of years ago

When one tectonic plate moves below another plate, this is formed

4,4

Subduction zone

When one tectonic plate moves below another plate, this is formed

• This causes Earth’s tectonic plates to move

5,4

Convection currents

This causes Earth’s tectonic plates to move
