The Top Layer Of The Ocean Floor Is Primarily

The ocean floor is just the bottom of the ocean so it s nothing but a boundary.

The top layer of the ocean floor is primarily.

The oceanic crust composed of sima mafic rocks and basalt. Thermocline the middle layer of the ocean that is about 700 m deep and the temperature drops faster than any other zone. Most of the rest is basalt. Includes the asthenosphere and lower lithosphere.

The flat deep portions of the ocean floor. Outermost layer of the two mantle layers. The warm top layer of the ocean that is mixed by currents and is about 300 m deep. Composed of solid rock most of which flows due to convection currents within the mantle.
