Plate Boundaries

Front

What is a divergent boundary?

Back

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

Front

What geologic feature is commonly found at divergent boundaries?

Back

Mid-Ocean Ridge is commonly found at divergent boundaries, where new oceanic crust is formed.

Front

What process occurs at divergent boundaries between oceanic plates?

Back

Sea floor spreading occurs at divergent boundaries between oceanic plates, where magma rises to create new ocean floor.

Front

What type of plate movement occurs at convergent boundaries?

Back

At convergent boundaries, tectonic plates move towards one another.

Front

What is the result of two oceanic plates converging?

Back

When two oceanic plates converge, one plate may be subducted under the other, leading to the formation of volcanic island arcs.

Front

What is a transform boundary?

Back

A transform boundary is a type of plate boundary where two plates slide past each other horizontally.

Front

What is the primary cause of plate tectonics?

Back

The primary cause of plate tectonics is the heat from the Earth's interior, which creates convection currents in the mantle.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, often found at divergent boundaries.

Front

What happens to the crust at a divergent boundary?

Back

At a divergent boundary, the crust is pulled apart, allowing magma to rise and create new crust.

Front

What is subduction?

Back

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