Info About The Ocean Floor

The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.

Info about the ocean floor.

Mountains plains channels canyons exposed rocks and sediment covered areas. The ocean is like an entirely separate world. We know very little about the deep ocean floor and the life it holds due to the depth and the difficulties this creates for scientists. Seabed contains several hundred years worth of cobalt and nickel.

The ocean floor has the same general character as the land areas of the world. The ocean floor covers 70 of the earth s surface. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. Exploration of the seafloor and the earth s crust.

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. Sonar has revealed features such as seamounts submerged volcanic peaks which rise 1 000 m 3 300 ft from the sea floor and guyots flat topped seamounts. But then hydrothermal vents were discovered. There are trenches mountains volcanos and lakes and rivers.

Here are 15 crazy facts about the ocean floor. The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on. The research ship directs sound waves at the bottom and charts the echoes that bounce back to create a detailed map. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

Because the water around these depressions contains more salt than normal seawater it s denser and sinks into the depressions creating. Other articles where ocean floor is discussed. Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s what they discovered was that the magnetism of the ocean floor around. The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope.

Oceanographers use sonar to map the ocean floor. As seawater makes its way through layers of salt it forms little depressions on the ocean floor. In fact it has been said that we know more about the surface of the moon than about the deeper ocean trenches. In recent years satellite images show a very clear mapping of the seabed and are used extensively in the study and exploration of the ocean floor.
