Geologic Features

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often creating new crust as magma rises to the surface.

Front

What geologic feature is formed at a divergent boundary on land?

Back

A rift valley is formed at a divergent boundary on land.

Front

What is a transform boundary?

Back

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

Front

What geologic feature is commonly associated with transform boundaries?

Back

Earthquakes are commonly associated with transform boundaries.

Front

What is the San Andreas Fault?

Back

The San Andreas Fault is an example of a transform boundary located in California.

Front

What are convection currents?

Back

Convection currents are movements within the Earth's mantle that help drive the movement of tectonic plates.

Front

Where do convection currents flow?

Back

Convection currents flow in the mantle of the Earth.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is created at mid-ocean ridges as magma rises from the mantle.

Front

Where does molten material rise during sea floor spreading?

Back

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

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where new oceanic crust is created.
