Question

Which statement describes the process of subduction? Convection currents pull a plate into the mantle. One plate slides beneath another due to gravitational pull. Materials are transferred within Earth’s interior by density. Heat cycles in the mantle cause plates to constantly move.

Answer 1

Answer:

• Subduction is the geological process in which one plate moves under another due to gravitational pull. The regions where this process occurs called subduction zones.

• A subduction is a tectonic plate which is made up of crust and upper layer of mantle. These two layers are called as lithosphere.

• Example:  South America, central America and cascade volcanoes. In which the oceanic plate descends beneath a continental plate.  

Answer 2

The answer is B.one plate slides beneath another due to gravitational pull.
