Question

at divergent boundaries.

Answer 1

The tectonic cycle describes the movement of Earth's crust, including the formation of new oceanic crust at divergent boundaries through a process called seafloor spreading. At these boundaries, tectonic plates move apart, and magma from the mantle rises to fill the gap, solidifying to create new oceanic crust as it cools. This process occurs at mid-ocean ridges, where the earth's plates are actively diverging.
