Plate Tectonics Review part 2

A __________________ is the location where the edges of two tectonic plates meet.

• tectonic plate

• plate boundary

• hot spot

• volcano

A collision between two continental plates at a converging boundary produces

• rift valley

• the mid-ocean ridge

• mountain range

• deep ocean trench

A rift valley forms where two plates

• converge

• diverge

• transform

• collide

When plates collide and one lithospheric plate is pushed under another lithospheric plate this is known as:

• sea-floor spreading

• rifting

• subduction

• trenching

A place where two plates slip past each other, moving in opposite directions, is known as a

• rift valley

• convergent boundary

• transform boundary

• divergent boundary

Volcanic mountain ranges form along converging oceanic and continental plate boundaries due to

• the mid-ocean ridge

• an island arc

• a hot spot

• subducting plate

Old oceanic crust is pushed down into to the mantle to be recycled at a ____________plate boundary.

• convergent

• divergent

• transform

Oceanic plates are more dense than continental plates. If an oceanic plate collides with a continental plate, what will be the likely result?

• The continental plate will slide under the oceanic plate, creating an oceanic trench.

• The oceanic plate will slide under the continental plate, creating a rift valley.

• The continental plate will slide under the oceanic plate, creating a transform boundary.

• The oceanic plate will slide under the continental plate, creating an oceanic trench.

Most geologists think that the movement of Earth's plates is caused by

• subduction

• earth's magnetic field

• convection currents in the outer core.

• convection currents in the asthenosphere.

The place where two plates collide together is known as a ______________

• convergent boundary

• divergent boundary

• transform boundary

• rift valley
