Plate Tectonics

What drives tectonic plate movement? 

• gravity
• coriolis effect
• convection currents
• the earth's magnetic core

Transform boundaries are most likely to produce what phenomenon?

• volcanoes
• deep sea trenches
• underwater mountain ranges
• earthquakes

This land form can occur at a divergent plate boundary.

• trench
• mid-ocean ridge
• folded mountains
• fault

According to Wegener's hypothesis of continental drift, 

• Earth's surface is made up of seven major landmasses
• the continents DO NOT move
• Earth is slowly cooling and shrinking
• the continents were once joined together in a single landmass

The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion is the theory of

• subduction
• plate tectonics
• evolution
• seafloor spreading

A rift valley forms at a 

• convergent plate boundary
• divergent plate boundary
• transform boundary
• deep ocean trench

This begins at the mid-ocean ridge, new molten material from inside Earth rises, erupts, cools, and hardens to form a solid strip of rock.

• Ocean ridge
• Sea-floor spreading
• Magnetic strip
• Molten

The theory that pieces of the Earth's lithosphere are in constant motion, driven by convection currents in the mantle is called:

• Radiation
• Plate Tectonics
• Pangea
• Continental Divide

A break in the Earth's crust where slabs of rock slip past each other

• Volcano
• Mountain Chain
• Fault
• Rift

The youngest material of the ocean floor is found at mid-ocean _________.

• ridges
• trenches
• basins
• rifts
