1.

Dr. King and his team of geologists have been studying GPS data that shows that two plates moved apart. Which diagram shows what happened between the two plates as they moved away from each other?

Fossil remains of Lystrosaurus (an extinct four-legged animal) have been discovered in India and South Africa.
