Plate Boundaries

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, often resulting in sea floor spreading.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates collide, leading to mountain formation or subduction.

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener proposed the theory of continental drift, suggesting that continents were once joined together.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process where molten material rises from the mantle at mid-ocean ridges, creating new oceanic crust.

Front

What was the name of the supercontinent that existed millions of years ago?

Back

The supercontinent was called Pangea.

Front

What is the theory of plate tectonics?

Back

The theory of plate tectonics states that the Earth's crust is divided into plates that are in constant, slow motion.

Front

What geological feature is formed at a convergent boundary?

Back

Mountains or deep ocean trenches can form at convergent boundaries.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, new crust is created as tectonic plates pull apart.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.
