Question

Which is responsible for the
formation of mid-ocean
ridges?
continental drift
convection currents
subduction of tectonic
plates
seafloor spreading

Answer 1

The formation of mid-ocean ridges is primarily associated with **seafloor spreading**. This process occurs when tectonic plates move apart at divergent boundaries, allowing magma to rise from the mantle and create new oceanic crust, which forms the mid-ocean ridges. While convection currents in the mantle drive the movement of tectonic plates, the specific mechanism leading to the formation of mid-ocean ridges is seafloor spreading.
