17.3 History of Plate Tectonics Quizizz

Which theory states that Earth’s crust and rigid upper mantle move in different directions and at different rates over Earth’s surface?

• Continental drift

• plate tectonics

• slab pull

Tectonic plates interact at places called plate

• boundaries

• reversals

• subsections

Places where tectonic plates move apart are called

• convergent boundaries

• divergent boundaries

• transform boundaries

Where are most divergent boundaries found?

• along coastlines

• on continents

• on the seafloor

What happens along a divergent boundary?

• Continental mountain ranges form.

• New ocean crust forms.

• Oceanic plates are subducted into the mantle.

The Mid-Atlantic Ridge is an example of a

• convergent boundary

• divergent boundary.

Places where tectonic plates come together are called

• convergent boundaries.

• divergent boundaries

• transform boundaries

Convergent boundaries are classified according to the

• types of fossils found at the boundaries.

• rate at which the plates collide.

• type of crust involved.

Oceanic crust is made mostly of

• sediments

• granite

• basalt

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

• divergent boundaries

• subduction zones

• rift valleys
