Make Up A Majority Of The Ocean Floor Worldwide

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.

Make up a majority of the ocean floor worldwide.

Seawater water that makes up the oceans and seas covering more than 70 percent of earth s surface. The average depth of the abyssal plains below sea level is about. The deepest segments of the ocean floor are found. That means it is also high tide at all other coasts throughout the world.

Basalt and gabbro make up a majority of the ocean floor worldwide. Make up a majority of the ocean floor worldwide in trenches associated with subduction zones the deepest segments of the ocean floor are found. Which trench includes the world s deepest sea floor. The form and topography depth profile of the ocean floor is termed.

At the equatorial ocean basins sea surface temperatures may reach 30 c or greater. Covered by sand and gravel introduced by rivers at deltas c. Make up a majority of the ocean floor worldwide. In trenches associated with subduction zones.

Make up a majority of the ocean floor worldwide. The crust overlies the solidified and uppermost layer of the mantle the crust and the solid mantle layer together constitute oceanic lithosphere. Make sure you thank the ocean. Seawater is a complex mixture of 96 5 percent water 2 5 percent salts and smaller amounts of other substances including dissolved inorganic and organic materials particulates and a few atmospheric gases.

Exposed at the surface of the sea floor b. Which trench includes the world s deepest sea floor more than 11 km below sea level. 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. Most of the igneous rocks within oceanic abyssal plains are.

Oceanic crust is the uppermost layer of the oceanic portion of a tectonic plate it is composed of the upper oceanic crust with pillow lavas and a dike complex and the lower oceanic crust composed of troctolite gabbro and ultramafic cumulates. The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The deepest segments of the ocean floor are found. The form and topography depth profile of the ocean floor is termed.

Covered by clay and the skeletal remains of. Make up a majority of the ocean floor worldwide. The two most abundant rocks within oceanic crust are. The vast majority of the cables that power the internet allowing access to it across the entire globe are.
