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, often seen in mid-ocean ridges.

Front

What geological feature is created at a divergent boundary in the ocean?

Back

Mid Ocean Ridge.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process that occurs at a divergent oceanic boundary where new oceanic crust is formed as magma rises to the surface.

Front

What occurs because of convection currents in the mantle?

Back

Tectonic plates on the crust move.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move towards each other, often resulting in one plate being forced beneath another.

Front

What geological feature is formed at a convergent boundary?

Back

Features such as mountain ranges, deep ocean trenches, and volcanic arcs can be formed at convergent boundaries.

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 the main process that occurs at a divergent oceanic boundary?

Back

New oceanic crust is created.

Front

What is subduction?

Back

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

Front

What is the role of convection currents in plate tectonics?

Back

Convection currents in the mantle drive the movement of tectonic plates on the Earth's surface.
