The Theory of Plate tectonics

What is the driving force for plate tectonics?

• gravity slab pull

• the push of the mid-ocean ridge

• the gravity of the Moon and Sun

• mantle convection

If a divergent plate boundary is found within a continent,

• a line of volcanoes forms.

• a subduction zone forms.

• the continent rifts apart.

• none of these.

In the Hawaiian islands, the youngest volcano

• is about to subduct into a deep-sea trench.

• is above a hotspot.

• is above a mid-oceanic ridge in the Pacific.

• is topped by limestone.

. Plate tectonics theory says that

• Earth’s geography has been the same for all geologic time.

• Earth’s geography is continually changing.

• all geological activity happens at plate boundaries.

• continents drift but scientists do not yet know why

How can two lithospheric plates move relative to each other?

• They can only converge or diverge.

• They can only collide or slide along each other.

• They can collide, pull apart, or slide against each other

• They can only move toward each other.

• the locations of earthquake faults.

• mid-ocean ridges.
