Plate Tectonics - BrainPop (NEW)

Front

What is a Divergent Boundary?

Back

A type of plate boundary where two tectonic plates move away from each other, often creating new oceanic crust through sea-floor spreading.

Front

What is a Convergent Boundary?

Back

A type of plate boundary where two tectonic plates collide, leading to the formation of mountains, trenches, or volcanic activity.

Front

What is a Transform Boundary?

Back

A type of plate boundary where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is a Trench?

Back

A deep underwater valley formed at a convergent boundary where one tectonic plate is being subducted under another.

Front

What is Sea-Floor Spreading?

Back

The process by which new oceanic crust is created at divergent boundaries as tectonic plates move apart.

Front

What is Pangaea?

Back

A supercontinent that existed millions of years ago, consisting of all the Earth's landmasses joined together.

Front

What evidence supports the theory of Continental Drift?

Back

Fossil discoveries, similar rock formations, and the fit of continental coastlines.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact at their boundaries, causing geological activity.

Front

What causes earthquakes?

Back

Earthquakes are caused by the sudden release of energy in the Earth's crust, often at transform boundaries.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.
