Plate Boundaries

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often resulting in one plate being forced below the other, leading to subduction.

Front

What is Pangaea?

Back

Pangaea is the name of the supercontinent that existed millions of years ago, where all the continents were joined together.

Front

Who is Alfred Wegener?

Back

Alfred Wegener is the scientist credited with the theory of continental drift, which later contributed to the development of the theory of plate tectonics.

Front

What is a tectonic plate?

Back

A tectonic plate is a large slab of the Earth's lithosphere that moves over the semi-fluid asthenosphere, causing geological activity.

Front

What feature is created by a divergent boundary on land?

Back

A divergent boundary on land creates a Rift Valley.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What is a transform boundary?

Back

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

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another plate and sinks into the mantle.

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by divergent tectonic plates, where new oceanic crust is created.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, characterized by steep walls and a central block.
