Tectonic Plates Review

When oceanic plate subducts, a ____ forms.

• ridge

• trench

• tidal wave

• mountain

Answer explanation

When oceanic plate subducts, a trench forms, not a ridge, tidal wave, or mountain. Trenches are deep depressions in the ocean floor where subduction occurs.

What type of boundary is characterized by two tectonic plates moving towards each other?

• Transform

• Convergent

• Divergent

• Subduction

Where in the Earth does the convection the drives plate tectonics occur?

• Crust

• ocean 

• mantle

• core

Answer explanation

Convection that drives plate tectonics occurs in the mantle, not in the crust, ocean, or core.

What is true about Earth's continents?

• they are part of tectonic plates

• they float on top of the ocean

• they sit on top of a plate

• they float on oceanic crust

Answer explanation

What type of boundary is characterized by two tectonic plates sliding past each other?

• Subduction

• Convergent

• Divergent

• Transform

The mid-ocean ridge forms at this type of boundary:

• divergent

• transform

• subduction

• convergent

Answer explanation

The mid-ocean ridge forms at a divergent boundary where tectonic plates move away from each other, allowing magma to rise and create new oceanic crust.
