TCI Lesson 3 Test Review

Rocks on either side of the mid-ocean ridge slowly pull away from each other, allowing molten rock to rise & solidify.

_____________________ motion can cause subduction.

The rock in the ____________________ is so hot that it flows slowly and slightly (like cake batter).

The hypothesis that the continents slowly drifted across Earth’s surface after being a part of one landmass is _______.

Most of Earth's active volcanoes and earthquakes are located in ________________.

Where does most of Earth's seismic activity occur?

_____________ boundaries often cause earthquakes.

________________ motion occurs at the mid-ocean ridge.

What are the three processes that drive plate motion?

Alfred Wegener's hypothesis of continental drift was rejected because _________________.

In subduction, the less dense plate slides underneath the denser plate.

Plates move toward each other (collide) at _______________ boundaries.

Seismic waves change _________ and ________ based on the density of the rock they're traveling through.
