Why do convection currents move?

Less dense material rises, cools down and then sinks

Where are the oldest rocks in the ocean found?

On the edges of the ocean, by the continents

What happens to rocks heated in our mantle?

They are less dense, so they rise

Which of the following statements is true?

According to relative dating, layer B is older than layer A

Which of the following is true about P-Waves?

They are the first waves to hit after an earthquake

What do you think Wegener would have liked to know to support his Theory of Continental Drift?

Convection Currents in the mantle move Earth's Plates

What causes Mt. Everest to continue growing?

The Indian Plate converging with the Eurasian Plate
