Mid-ocean ridges occur at diverging plate boundaries. Convection currents in the lower mantle pull the plates away from each other . As the plates move apart, lower mantle material is drawn toward Earth's surface. The rock of the lower mantle is hot, flexible, and solid. This rock is solid because of the great pressure of the layers above it. However, as the rock of the lower mantle rises, the pressure drops and the material melts.
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
One of the midocean ridges is, but others are in other oceans, seas, and bays.
The main mechanism for melting at spreading ridges is decompression melting. As tectonic plates diverge at these ridges, the mantle material rises to fill the gap. This rise reduces the pressure on the mantle rocks, causing them to melt and form magma. The resulting magma then contributes to the formation of new oceanic crust as it erupts and solidifies at the surface.
The lines representing midocean ridges are jagged due to the tectonic activity associated with seafloor spreading. As tectonic plates diverge, magma rises to create new oceanic crust, resulting in irregular formations. Additionally, the process of plate movement can lead to fractures, faults, and other geological features that contribute to the jagged appearance. This dynamic environment contrasts with smoother features typically seen in more stable geological areas.
At mid-ocean ridges, tectonic plates are moving apart, creating new oceanic crust through volcanic activity. This results in the formation of underwater mountain chains and hydrothermal vents, which support unique ecosystems due to the high temperatures and mineral-rich waters.

The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.
