Places where tectonic plates move apart are called

• divergent boundaries.
• convergent boundaries.
• subduction zones.
• transform boundaries.

Where are most divergent boundaries found?

• on the seafloor
• along coastlines
• on continents
• at subduction zones

What happens along a divergent boundary?

• New ocean crust forms.
• Continental mountain ranges form.
• Oceanic plates are subducted into the mantle.
• Ocean basins become smaller.

The Mid-Atlantic Ridge is an example of a

• divergent boundary.
• subduction zone.
• convergent boundary.
• transform boundary.

Convergent boundaries are classified according to the

• type of crust involved.
• types of fossils found at the boundaries.
• compass direction of movement of the plates.
• rate at which the plates collide.

Oceanic crust is made mostly of

• basalt.
• granite.
• water.
• sediments.

Which of the following features forms when two oceanic plates converge?

• subduction zones
• magnetic reversal patterns
• divergent boundaries
• rift valleys
