Topic 5 Test Retake: Plate Tectonics

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at divergent plate boundaries, where tectonic plates move apart.

Front

What type of plate boundary is associated with seafloor spreading?

Back

Divergent boundary.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, often forming mountains, deep ocean trenches, or volcanic arcs.

Front

What geological feature is formed at an oceanic-oceanic convergent boundary?

Back

Deep Ocean Trench.

Front

What evidence supports the Plate Tectonics Theory?

Back

Evidence includes the fit of continents, fossil similarities across continents, and the distribution of earthquakes and volcanoes.

Front

What are convection currents?

Back

Convection currents are the movement of fluid caused by differences in temperature and density, which drive the movement of tectonic plates.

Front

What is the Theory of Plate Tectonics?

Back

The Theory of Plate Tectonics explains how the Earth's lithosphere is divided into tectonic plates that move over the asthenosphere.

Front

What happens at a transform boundary?

Back

At a transform boundary, tectonic plates slide past each other, which can cause earthquakes.

Front

What is an example of a transform boundary?

Back

The San Andreas Fault in California.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics at divergent boundaries.
