What are the deep ocean currents?
These currents make up 90% of the ocean waters.These waters move around the ocean basins due to variations in the density and gravity.Deep waters sinks into the deep ocean basins at high latitudes , where the temperatures are cold enough to cause the density to increase.
What caused circulations in deep water?
The movement of deep water in the ocean basins is by density driven forces and gravity.
Why is the ocean so deep?
The ocean is deep because of the Earth's crust, which is thinner under the ocean than on land. This allows more space for water to fill, creating the deep ocean basins. Additionally, the movement of tectonic plates can also create deep trenches in the ocean floor.
What were the goals of the deep sea drilling project?
To investigate the evolution of ocean basins by core drilling of ocean sediments and underlying oceanic crust.
Sediments are spread over wide areas of the deep ocean basins by?
turbidity currents, which are fast-moving underwater currents that carry sediment down into the deep ocean basins. These currents can transport large volumes of sediment over long distances before depositing them on the ocean floor.
What are the three main vertical divisions of the ocean based on the depth and distance from the shore?
The Intertidal zone, Coastal Ocean, and the Open Ocean
What are four main features of the deep ocean basins?
They are: Continental Shelf Continental Slope Abyssal Plain Ocean Deeps
How does volcanic dust become sediment in the deep-ocean basins?
The dust falls from the atmosphere over the ocean, sinks through the water column and ends up as sediments on the ocean floor.
What are the three regions of the ocean floor?
the continental Margin, Ocean Basin Floor and Mid-Ocean ridge :D
What best describes seamounts and islands of the deep ocean basins?
piles of basaltic lava flows built up from the ocean floor by multiple, summit and flank eruptions
Define ocean basin?
Hydrologically, an oceanic basin may be anywhere on Earth that is covered by seawater, but geologicallyocean basins are large geologic basins that are below sea level. Geologically, there are other underseageomorphological features such as the continental shelves, the deep ocean trenches, and the underseamountain ranges (for example, the mid-Atlantic ridge) which are not considered to be part of the ocean basins; while hydrologically, oceanic basins include the flanking continental shelves and shallow, epeiric seas.
