plate tectonics and boundaries

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.

There are three types of plate boundaries. Which choice is NOT a type of plate boundary?

• convergent

• insurgent

• divergent

• transform

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

• the oceanic crust is melting.

• the denser oceanic crust is subducting under the less dense oceanic crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.

The 2004 Indian Ocean tsunami was caused by a shift in two plates that pushed one section of the sea floor under another section of the sea floor by 5 meters. What type of boundary is this?

• divergent

• convergent

• transform

• metamorphic

___________ currents in the Earth's asthenosphere cause plate to shift at their boundaries. This movement also causes earthquakes and volcanic activity.

• conduction

• convection

• radiation

• ocean

• At convergent boundaries (oceanic vs. continental)

• At divergent plate boundaries (oceanic vs. oceanic)

• At transform plate boundaries
