Question

represents volcanoes forming by subduction?
yes no
continental plate
continental plate
continental plate
oceanic plate

Explanation:

Subduction occurs when a dense oceanic plate is forced under a less dense continental plate, melting and forming volcanoes. The second diagram shows an oceanic plate moving under a continental plate (with volcanic mountains forming), which matches subduction. The first is a continental-continental collision (no subduction, just uplift), the third is continental plate bending without subduction, the fourth is an oceanic plate with a hot spot, not subduction.

Answer:

• First diagram: No
• Second diagram: Yes
• Third diagram: No
• Fourth diagram: No
