Front

What type of crust will subduct if two plates converge?

Back

Oceanic crust subducts when two tectonic plates converge.

Front

What is the process that occurs at a divergent oceanic boundary that creates new crust?

Back

Seafloor Spreading is the process that creates new oceanic crust at divergent boundaries.

Back

The magma melts and rises.

Front

What is the main driving force behind plate tectonics?

Back

Mantle convection drives the movement of tectonic plates.

Front

What happens to oceanic crust at subduction zones?

Back

Oceanic crust is forced down into the mantle, where it melts.

Front

What is the significance of the Ring of Fire?

Back

The Ring of Fire is an area with a high level of tectonic activity, including earthquakes and volcanoes, located around the edges of the Pacific Ocean.
