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 mid-ocean ridges are made almost entirely of basalt, because this is where new oceanic lithosphere is being formed. In fact, oceanic plates in there entirety are made up almost entirely of basalt.(igneous rock)
Basalts tend normally to form at mid-ocean ridges or at inter plate hotspots. However a specific type of Basalt known as Boninite which has a high silica and magnesium content and which is formed in the fore-arc and back-arc basins of subduction zones. This however is NOT a primary basalt.

While it is molten it is above the Curie temperature and is not magnetic, as it cools below this temperature the ambient magnetic field becomes "frozen" into the basalt.
At transform faults or transform zones.
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
realate the high tempertures measured at the mid-ocean to the formation of basalt at the ridges
One of the midocean ridges is, but others are in other oceans, seas, and bays.
Basalt can be hundreds of millions of years old or it can be minutes old, just solidified from basaltic magma at the mid-ocean ridges.
(1)midocean spreading ridges, (2) subduction zones, and (3) transform faults.Normal fault, Reverse fault, and strike-slip fault
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.
Yes, basalt forms on oceanic crust through volcanic activity at mid-ocean ridges and hotspot volcanoes. It is the most common rock type on the ocean floor and is created from the solidification of molten lava.
