Question and answer
Subduction occurs because the sea floor is ?more dense than the continental floor, less dense than the continental floor, more buoyant than the continental floor, lighter than the continental floor
In geology, subduction is the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate, sinking into the Earth's mantle, as the plates converge. [ A subduction zone is an area on Earth where two tectonic plates move towards one another and one slides under the other. Rates of subduction are typically measured in centimeters per year, with
the average rate of convergence being approximately 2 to 8 centimeters per year (about the rate a fingernail grows) ]

User: The balance between the downward push of continents and the upward push of the mantle is called isostasy.
