Three Layers Of The Ocean Floor
The water temperature is constantly near freezing and only a few creatures can be found at these crushing depths.
Three layers of the ocean floor. The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere. Bathypelagic zone midnight zone the bathypelagic layer is found between 3 281 feet and 12 124 feet just above the abyss. Only the hardiest deep diving submersibles can explore this zone due to the immense pressure. Measure 3 4 cup of corn syrup mix with black food coloring and pour into the bottom of your mason jar.
On average oceanic crust is only 6 to 7km thick compared to 35 to 40km for con tinental crust. The deepest fish ever discovered was found in the puerto rico trench at a depth of 27 460 feet 8 372 m. It is the pitch black bottom layer of the ocean. This layer extends from 6 000 meters 19 686 feet to the bottom.
Oceanic crust the outermost layer of earth s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges which occur at divergent plate boundaries. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle. It is composed of several layers not including the overlying sediment. No light at all.
Near freezing around 35 37 f 2 3 c for most of its mass. The ocean has three main layers. Three quarters of the area of the deep ocean floor lies in this zone. Layers of the ocean.
The thermocline separates the surface from the deep ocean. The name abyss comes from a greek word meaning no bottom because they thought the ocean was bottomless. Three quarters of the ocean floor lies within this zone. The deepest fish ever discovered was found in the puerto rico trench at a depth of 27 460 feet 8 372 meters.
The ocean basins are characterized not only by lying in deep water the ocean floor averages about 4km below sea level but also by being underlain by a thin layer of crust. You are going to be making several layers of the ocean floor in this ocean layers experiment. Around 75 of the ocean floor lies at depths within this layer. This layer is also called the midnight or the dark zone.
Due to density differences the surface and deep ocean layers do not easily mix. The surface ocean which is generally warm and the deep ocean which is colder and more dense than the surface ocean and the seafloor sediments. Hadalpelagic zone beyond the abyssopelagic zone lies the forbidding hadalpelagic zone. Oceanic crust is about 6 km 4 miles thick.
