Basalt is the igneous rock which makes up most of the ocean floors. It is smooth and velvety-black in appearance and very hard. New seafloor is constantly produced at the mid-ocean rifts, where areas between spreading tectonic plates are infilled with rapidly cooling lava.
Magma from the uppermost mantle, forming the rock basalt.
Basalt is the igneous rock that is most abundant in the oceanic crust. It is also the most abundant volcanic rock on earth as well.

Most of the rocks of the earth's crust are igneous, although sedimentary rocks usually cover them. Basalt is the most common type of igneous rock and it covers the ocean floor and thus, exists over two-thirds of the earth's surface!
The most abundant mineral in the ocean floor is basalt. There are also some other minerals like sand, gravel and granite that are found in the ocean floor.

As it turns out, most of the ocean floor is basalt, and most of the continents are granite.

The volcanic rock that makes up most of the ocean floor is called sediment.

Ocean basins are primarily made of the igneous rock, basalt.
Igneous rock is by far the most common rock of the crust.
Most of the ocean floor is made up of ocean plains.
Basalt is the most common extrusive igneous rock.
The ocean floor is the most anaerobic zone in the ocean.
Tsunami are waves caused by sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.
