Fossil remains of Lystrosaurus have been discovered in India and South Africa. When they were living, 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?

Back

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

Options: Diagram A: Two plates are hitting each other, and the plates are breaking into pieces, creating sand., Diagram B: Two plates are pushing against each other, causing the edges to bend upward., Diagram C: One plate is going underneath the other plate and sinking into the soft rock below., Diagram D: One plate is going underneath the other plate and sinking into the ocean below.

Back

Diagram C: One plate is going underneath the other plate and sinking into the soft rock below.

What could explain how similar rock formations in Brazil and South Africa got so far apart?

Back

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