Dynamic Earth Review pd1-3

The theory of continental drift suggests that the

• continents moved due to changes in the Earth's orbital velocity

• continents moved due to the Coriolis effect caused by the Earth's rotation

• present-day continents of South America and Africa are moving toward each other

• present-day continents of South America and Africa once fit together like puzzle parts
