Plate Boundaries Review

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates collide, often forming mountains or causing subduction.

Front

What is a divergent plate boundary?

Back

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

Front

What is a transform plate boundary?

Back

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

Front

What are fault lines?

Back

Fault lines are fractures in the Earth's crust where blocks of land have moved past each other, commonly found at transform boundaries.

Front

What is convection in the mantle?

Back

Convection in the mantle is the process where hot magma rises and cooler magma sinks, driving the movement of tectonic plates.

Front

What happens when two continental plates collide?

Back

When two continental plates collide, they can create mountain ranges due to the compression and folding of the Earth's crust.

Front

What is subduction?

Back

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

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates pull apart.

Front

What geological features are commonly found at divergent boundaries?

Back

Divergent boundaries often feature mid-ocean ridges and rift valleys.

Front

What geological features are commonly found at convergent boundaries?

Back

Convergent boundaries can create mountain ranges, deep ocean trenches, and volcanic arcs.
