Similar rock formations have been discovered in the U.S. and Portugal. These rock formations formed at the same time and are made of the same types of rocks. What could explain how these rocks got so far apart?

• The US and Portugal are parts of different plates. The plates floated away from each other across the ocean

• The US and Portugal are parts of different plates. The plates were sometimes pushed far apart by earthquakes

• The US and Portugal are parts of different plates. The plates slowly moved apart as new plates from underneath got added between them

• The US and Portugal are parts of different plates. The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates

Fossil remains of Lystrosaurus (an extinct four-legged animal) have been discovered in India and South Africa. When they were alive, all the Lystrosaurus lived together on land, and they could not swim. However, now there is an ocean between the Lystrosaurus fossils. What could explain how these fossils got so far apart?

• India and South Africa are parts of different plates. The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years.

• India and South Africa are parts of different plates. The plates floated away from each other across the ocean.

• India and South Africa are parts of different plates. Earthquakes caused the plates to slowly move apart as new plates from underneath got added between them over millions of years.

• India and South Africa were part of the same plate millions of years ago. The plate was cracked into two and pushed far apart by earthquakes.
