Plate Tectonics Review!

Identical rock types, identical fossils, and very similar mountain ranges are found on different continents that are separated by a wide ocean. Which of these best explains these observations

• Organisms traveled between these continents on land bridges.

• The same forces erode mountains in different locations.

• These continents were joined together at one time in the past.

• Some rock types are very common and are found everywhere.

Which of the following best explains how lithospheric plates move across the Earth?

• Hot magma rises, shifts plates, and sinks as it cools

• Denser magma rises and carries plates as it melts

• Plates are carried by oceanic currents

• The motion of the Earth’s rotations forces plates to move
