Final answer:
Subduction and Seafloor Spreading are the two integral processes involved in the movement of the ocean floor. Subduction happens in oceanic trenches resulting in the destruction of old crust, while seafloor spreading occurs at mid-ocean ridges creating new crust.
Step-by-step explanation:
The two processes that work together to move the ocean floor, creating new ocean crust along mid-ocean ridges and destroying ocean crust along trenches, are Subduction and Seafloor Spreading. These processes are part of Plate Tectonics, an influential geological theory that depicts the Earth's crust as a collection of large moving pieces, or tectonic plates.
Subduction primarily occurs in oceanic trenches, where one plate is forced beneath another. This process helps accommodate the crust newly formed at spreading centers by consuming it back into the Earth's mantle.
On the flip side, Seafloor Spreading takes place in mid-ocean ridges where new crust is created, marked by molten rock rising from beneath and hardening to form new oceanic crust. This, indeed, is a perpetual process that results in the ceaseless formation and disintegration of the Earth's outer shell.
