Plate Tectonics

This boundary is described by two plates moving away from eachother along the edges and separating. The resulting gap allows magma to rise and create new crust, forming new lithosphere.

• Divergent Boundary

This boundary is described as two plates moving past eachother ALONG THE EDGES horizontally.  These boundaries will get stuck or lock against eachother causing earthquakes when they slip and release.

This boundary is described as moving toward one another  When the plates are both continental plates the will crumple up and form a mountains. When they are continental and oceanic plates, subduction occurs  and earthquakes and volcanoes form.

In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

• The strong ocean currents are undermining both areas causing earthquakes.

• Both areas are located near the edge of the Pacific Ocean, the unstable sand causes earthquakes.

• Both areas are subjected to strong ocean wind and waves that causes earthquakes.

• Both areas are on the boundary of active plates, the motion of the plates causes earthquakes.

The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.

Subduction zones occur on Earth where dense oceanic crust dives under more buoyant continental crust. These boundaries are characterized by a deep ocean trench next to a high continental mountain range, large numbers of earthquakes and volcanoes. All of this is further evidence for the

• big bang theory.
• theory of plate tectonics.
• origin of the species.
• theory of natural selection.

The image shows the Pacific Ring of Fire, a region of high tectonic activity. What evidence supports the theory that the tectonic activity of the region is due to the subduction of tectonic plates?

• The region is bound by many oceanic trenches.
• North America seems to be colliding with Asia at the north of the ring.
• The Asia-Pacific region is dotted by many small and large islands
• The landmasses look like they would fit together like the pieces of a jigsaw puzzle.

What is the source of energy that drives plate movement?

• the subducton of the sea floor

• the different densities of the oceanic and crustal plates

• convection currents in the asthenosphere

• the friction force between the plates that move past each other
