Fossils of the Mesoaurus have been found on the continents of African and South America. Which statement is a logical conclusion from this evidence?

• African and South America had different climates that cause it to migrate.

• The 2 continents were once joined.

• Mesosaurus migrated across frozen land bridges.

• The 2 continents had underground tunnels that connected them.

Which statement best supports the claim that rock layers at the mid-oceanic ridge were younger than anywhere else on the oceanic floor>

• Plates drifting apart cause faults that cause earthquakes.

• Plates form cracks on the ocean floor when they move away from each other.

• Magma rises up and solidifies , forming new rock layers when plates move away from each other.

• Oceanic crust is pushed together when plates drift apart.

What geological evidence supports the theory of plate tectonic idea that plates are always in motion?

• Continents and oceanic plates have different densities.

• Seismic activity occurs along plate boundaries.

• Less dense plates subduct.

• Sizes and shapes of continents remain the same.
