They both can change the size of Earths Surface
They move the ocean floor as if it were on a giant conveyor belt.
Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics
the tectonic plates under the earths surface
Subduction of the ocean floor takes place at trenches.
Subductions causes the ocean floor to sink into deep-ocean trenches and the earths plates move apart from molten rock or magma ana the earths crusts rises a departs. Thank You, Professor Einstien
crust
sea floor spreading and landslides
The process in which the ocean floor sinks into the mantle is called subduction. This occurs at convergent plate boundaries, where one tectonic plate slides beneath another. Subduction zones are associated with deep-sea trenches and volcanic activity.
your answer is subduction
Subduction zones.
trenches
subduction is the answer.
