Convective flows of molten rock beneath the Earth's crust causes tectonic plates to spread apart in one area and to sink or be subducted beneath another plate at the opposite edge of the plate.

What in earths interior causes subduction and sea floor spreading?

Subduction and sea floor spreading are both a result of the movement of the tectonic plates.Plate Tectonics


What is the relation between rising and sinking material in the earths interior and subduction and rifting?

Rising material in Earth's interior typically leads to rifting, where tectonic plates move apart. This process creates new crust. Sinking material, on the other hand, is associated with subduction, where one tectonic plate slides beneath another, leading to the destruction of crust.


By which process is the earths crust returned to the mantle?

The process by which the Earth's crust is returned to the mantle is known as subduction. In subduction zones, oceanic plates are forced beneath continental plates, carrying crustal material back into the mantle where it is recycled. This process is a key part of the Earth's tectonic cycle.
