Plate Tectonics

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.

Observe the plate boundary shown here. What type of plate boundary is this? Many geologic events occur at these boundaries. Some are shown, but one is missing. What geologic event would you predict would occur at this plate boundary?

• convergent oceanic-oceanic plate boundary; volcano
• divergent oceanic-oceanic plate boundary; sea floor spreading
• convergent oceanic-continental plate boundary; earthquake
• convergent continental-continental plate boundary; mountain building
