TRUE OR FALSE

1. Earthquakes are associated with ridges.

2. The hot, molten material that rises towards the surface of the mid-ocean ridge flows sideways carrying the seafloor towards from the ridge.

3. When the magma flows out of the crack, it cools down and destroyed at the subduction zone.

4. Rocks far from the mid-ocean ridge are younger.

5. The rocks near the ridge cools down, it becomes denser and gravity pushes away the seafloor to the subduction zone.

6. The decomposition of radioactive elements causes heat in the interior part the Earth.

7. Seafloor spreading allows the creation of new bodies of water.

8. Due to the tremendous heat underneath the Earth's surface, the hot materials in the mantle sink because of its low density while the relatively cooler materials rise due to higher density.

9. Harry Hess together with Robert Dietz introduce the concept of Seafloor Spreading.

10. Rocks from the continent are younger than those at the ocean floor.​
