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
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
Subduction of the ocean floor takes place at trenches.
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.
Subduction occurs when one tectonic plate moves beneath another, leading to the formation of deep ocean trenches and volcanic arcs. Sea floor spreading happens when molten rock rises at mid-ocean ridges and forms new oceanic crust. Together, these processes play a significant role in the movement of Earth's tectonic plates, shaping the planet's surface through the formation of mountains, ocean basins, and other geological features.
