Where do most rocks have a basaltic composition?
on the ocean floor
What best describes the ocean floor?
It is varied and includes features such as submarine canyons, atolls, and mid-ocean ridges.
What term describes the process that creates new oceanic crust at mid ocean ridges?
Sea Floor Spreading
What term describes the process that creates new oceanic crust at mid-ocean ridges?
Sea floor Spreading! -Lucy laboy Thanks that really helped alot.
Is the floor near the mid ocean old?
No. The newest ocean floor is at the mid-ocean ridge.
Which best describes the composition of the ocean floor?
The ocean floor generally consists of basalt cooled from magma, and the overlying layers of sediment, both inorganic and organic.
Where do most rocks have a basaltic composition?
on the ocean floor
How can the composition of of the ocean floor be determined?
Ocean topography has been determined through sonar detection.
What term describes organisms that live in or in the ocean floor?
Benthos

What terms describes organisms that live on or in the ocean floor?
Benthos
Why do scientist look to the ocean floor to research the mantle?
Why do scientists look to the ocean floor to research the mantle? Because magma from the mantle flows out of active volcanoes on the ocean floor. These underwater volcanoes have given scientists many clues about the composition of the mantle.

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
