What is the ocean floor made of ? Which animals live on the sea floor? Plate tectonics and the ocean floor Bathymetry, the shape of the ocean floor, is largely a result of a process called plate tectonics. If you could sit right under a ridge, you would see rocks from the Earth’s mantle—the hot layer underlying the crust—melting and percolating up toward the seam between the two plates. The lack of weathering and erosion in most areas, however, allows geological processes to be seen more clearly on the seafloor than….

Another name for the ocean floor is oceanic crust. Basalt and and metamorphosed basalt - peridotite. GeochemistryThe most voluminous volcanic rocks of the ocean floor are the mid-oceanic ridge basalts, which are derived from low-potassium tholeiitic magmas. These rocks have low. Mu Silt, and Sand. none of the above.

The ocean floor is made of basalt that is formed at mid-ocean ridges where two tectonic plates move apart. The continents, which ar mostly lan are made of granite. The granite is less dense than the basalt, which is why the ocean flood is. Deep Ocean Ecosystems.

While most life on this planet requires sunlight to live, there is an. It is covered with thick layers of sand , mu and rocks. Cosmogenous sediments are the remains of space debris such as comets and asteroids, made up of silicates and various metals that have impacted the Earth.

It is composed of several layers, not including the overlying sediment. Oceanic crust is about km (miles) thick. By Jonathan Amos BBC Science Correspondent, San Francisco. The fashion labels whose clothes are made by prisoners.

The bottom of the ocean is dark, mysterious, and vast—nearly all of it unmapped. Today, however, scientists reveal the clearest map of the ocean floor ever. While these formations are human- made , they are only made of data. In other words, there are no physical lines on the ocean floor.

Most of the remaining features of the ocean floor result from large outpourings of magma, which typically form submarine volcanoes. The solid rock, called the basement, that acts as the floor of the deep ocean is different from that of the continents. Ocean crust is denser, thinner, darker-colore and contains more of the chemical elements iron and magnesium than continental crust. The basement of the ocean basins is mostly made of black, volcanic rock called basalt.

FIND OUT MORE Just a century ago, the ocean floor was largely unknown. Now we know that the deep oceans have features such as mountains, deep valleys, and vast plains. Many of these are formed by the movement of the tectonic plates that make up Earth’s crust.

The ocean is not just where the land happens to be covered by water. The sea floor is geologically distinct from the continents. It is locked in a perpetual cycle of birth and destruction that shapes the ocean and controls much of the geology and geological history of the continents. Then at what bearing are you proceeding is the main issue.

Bottom of the ocean floor is possible only if your starting point has ocean at its anti-pod. While you might expect the deepest part of the ocean to be among the quietest places on Earth, the recordings captured almost constant noise from both natural and man- made sources, said Robert Dziak, an oceanographer at NOAA. This too is imaginary. The ocean may hold the key for finding new medicines, but not if we don’t keep it – and everything that lives there – healthy and pollution free.

Do your part to protect coral reefs. Do not buy coral jewelry or home décor. And when snorkeling, fishing, or scuba diving, be careful to not touch or disrupt coral beds or the sea floor.
