Plate Tectonics and Landforms

Long, narrow depression formed at divergent boundaries between continental plates.

• Ocean Trench
• Rift valley
• Subduction

What is a subduction zone?

• where plates move into each other
• where plates are moving away form each other
• where plates move past each other
• area where one plate slips under another plate

What forms at a divergent boundary?

• mid-ocean ridges
• very tall mountains
• trenches
• volcanic islands

When the sea floor spreads apart, volcanoes and ridges are formed because

• underwater earthquakes form them
• sediments deposit forming ridges
• less dense magma moves to the surface as the plates pull apart
• ocean water pushes down surrounding sea floor pushing up the ridges

What is a fault?

• A crack in rock where two pieces move past each other
• The energy that is built up in rock
• It's Whitney's fault. Its always Whitney's fault.
• An area where lava erupts from the surface.

The San Andreas Fault in San Francisco is located along what type of boundary?

• Convergent boundary
• Transform boundary
• Divergent boundry
• Shearing boundary

What kind of plate boundary is shown here?

• divergent
• convergent
• transform
• strike slip

In which type of boundary do the plates go away from each other?

• convergent
• normal
• divergent
• transform

A subduction zone is formed...

• when one tectonic plate sinks below another
• at every type of convergent plate boundary
• at every type of divergent plate boundary
• at transform boundaries

Name the boundary

• convergent boundary
• divergent boundary
• transform boundary
• sergent boundary
