Question

Briefly explain the geological evolution of the relief feature marked ‘X’ below.

Answer 1

The geological evolution of the ‘X’ relief feature indicates seafloor spreading. Seafloor spreading is the formation of a new ocean floor near mid-ocean ridges. Magma erupts from beneath the Earth’s crust, cools, and produces a new crust. Over time, the ocean floor gradually spreads as older crust is pushed away.
