The fact that similar fossils are found on both sides of the ocean is evidence of

• magnetic reversal

• sonar

• continental drift

• plate boundaries

The movement of the tectonic plates is caused by

• the rotation of the earth

• convection currents in the Asthenosphere

• the gravity of the core

• the pressure of the atmosphere

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the tectonic plates are moving away from each other

• the continental crust is melting

• the more dense oceanic crust is subducting

• an ocean ridge is forming
