Unit 10: Earth Rocks Review

Scientists believe that about 299 million years ago, all the continents on the Earth were next to one another in a supercontinent called 'Pangea.' What has caused the continents to move to their positions today?

• Wind patterns push continents over time.

• Changes in oxygen levels have led to weathering and erosion.

• Thermal energy below the Earth’s surface moves continental plates.

• Molten rock from volcanoes pushes the continents apart.
