Question

Study this image.

The Asthenosphere is being divided by the Lithosphere on the left of the diagram. Oceanic crust is above the Lithosphere and continues until it reaches the Continental crust on the right. The Lithosphere layer on the right is moving left toward the Lithosphere layer on the left that is moving right and down. Two volcanoes are above the area where the lithosphere layers meet.

Which statement correctly explains what is happening?

Oceanic and continental plates are colliding.
Oceanic and continental plates are shifting past each other.
Two continental plates are forming a large mountain.
Two oceanic plates are creating several island chains.

Answer 1

Oceanic and continental plates are colliding.

This diagram shows a convergent boundary where the denser oceanic lithosphere is being forced down (subducted) beneath the continental lithosphere. The subduction melts mantle rock and produces magma that rises to form volcanoes on the continental side.
