Question 7 (1 point)

Why do the tectonic plates of ocean plates subduct under land mass plates?
Ocean plates move slower than land plates, so land plates move above them
Ocean plates are denser than land plates, so they sink under the land plates when the two plates converge
Land mass plates are made of porous materials, which absorb the water in the oceanic plates
Ocean plates are made of metals, not rocks, so they move lower due to gravity

Answer 1

Ocean plates subduct under land mass plates because they are denser.

Step-by-step explanation:

Ocean plates subduct under land mass plates because they are denser than land mass plates. When two plates converge, the denser oceanic plate sinks below the less dense continental plate. This process is called subduction, and it is driven by differences in density and gravity.
