At location A, what is happening as the two plates collide?

• The denser oceanic crust is subducting under the continental crust, where it is melted and forms lava.
• The plate is moving over a hot spot, forming an island chain.
• The denser continental crust is subducting under the oceanic crust, where it is melted and forms lava.
• The continental crust is heating up and melting to form the magma for the volcanoes.

What type of boundary is occurring at A?

Back

Divergent

Front

What type of boundary is occurring at B? Options: Divergent, Convergent, Transform, Subduction

Front

What causes the plates to move?

Back

Convection currents in the mantle.

Front

Which types of crusts have formed the volcanic Andes Mountains of South America?

Back

One continental crust and one oceanic crust converge. The oceanic crust subducts to melt, forms into magma and erupts.

Front

What is occurring for the Himalayan Mountain Range to form?

Back

Two continental plates (India and Asia) are colliding and pushing the Earth upwards.
