Earthquakes are detected and measured by?

• Seisomometer

• Geiger Counter

• Doppler Radar

• Oil well momitors

What do you expect to find at mid-ocean ridge?

• Reverse fault

• Young rocks

• Ancient rocks

• Thick sediments

Where do most earthquakes occur?

• Along plate boundaries

• In the oceans

• On ridges

• Along the Moho discontinuity

Transform boundaries occur when

• Two plates slide by each other without formation or loss of crust

• Two plates come together and transform each other

• One plate slides under another plate

• Ridges are formed

A geologic feature that was produced by divergent boundaries is?

• The Alps

• Mid-Atlantic ridge

• Marianas Trench

• Japan

The only type of crust that will subduct if two plates converge is...

• Oceanic

• Continental

How do plates move at convergent boundaries?

• Collide together
• Separate apart
• Slide past each other
• All of the above

Which is the current theory of Earth's geologic activities such as earthquakes, volcanic eruptions, and tsunamis?

• Continental Drift

• Plate Tectonics

• Sea-floor spreading

• Mantle convection

Tsunamis in Japan are caused by...

• Convergent boundary with subduction
• Convergent boundary with NO subduction
• divergent boundary
• transform boundary

When will subduction of a tectonic plate occur?

• Collision of 2 land plates
• Collision of land and ocean plates
• Separation of land plates
• Separation of oceanic plates
