6.E.2.2 Plate Tectonics

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 sea-floor spreading.

Front

What formations occur at divergent boundaries?

Back

At divergent boundaries, sea-floor spreading, mid-ocean ridges, volcanoes, and earthquakes can occur.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a ring of volcanoes that encircles the Pacific Plate, known for its high volcanic activity.

Front

Where does molten material rise during sea-floor spreading?

Back

Molten material rises from the mantle at mid-ocean ridges during sea-floor spreading.

Front

How does oceanic crust compare to continental crust?

Back

Oceanic crust is thinner, younger, and more dense than continental crust.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath the other.

Front

What can happen at convergent boundaries?

Back

At convergent boundaries, mountains, earthquakes, and volcanic activity can occur.

Front

What is a transform boundary?

Back

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

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another, often leading to volcanic activity.

Front

What are mid-ocean ridges?

Back

Mid-ocean ridges are underwater mountain ranges formed by the upwelling of magma at divergent boundaries.
