The most prominent feature on the ocean floor is basalt. There are other types of salts and silt as well which makes up the ocean floor. ADDED: Almost there. Yes, the deep ocean floors are of basalt, but though there are areas of bare rock, most are covered with deep layers of sediment. Not "other types": basalt is neither a silt nor salt.
As it turns out, most of the ocean floor is basalt, and most of the continents are granite.
Abyssal plain is a land feature similar to the continental slope, located at the base of the continental rise. It is a flat area of the ocean floor covered with sediment and is considered the most level part of the ocean floor.
Oceanic plates diverge at mid-ocean ridges, creating new ocean floor as magma rises to the surface and solidifies. This process is called seafloor spreading, and it results in the formation of new oceanic crust.
Large flat areas of the ocean floor are called abyssal plains. These regions are typically covered in thick layers of fine sediment and are among the flattest, most featureless parts of the ocean floor. Abyssal plains are found at depths between 3,000 and 6,000 meters.
