What else can I help you with?
Where do most rocks have a basaltic composition?
Most rocks with a basaltic composition are typically found in oceanic crust, such as the ocean floors and mid-ocean ridges. Basaltic rocks are also common in volcanic regions like Hawaii and Iceland.
What term describes the process that creates new oceanic crust at mid ocean ridges?
Sea Floor Spreading
Is the floor near the mid ocean old?
No. The newest ocean floor is at the mid-ocean ridge.
What is the floor of the ocean called?
The floor of the ocean is called the seabed or ocean floor. It is made up of different features such as abyssal plains, trenches, ridges, and volcanoes.
What best describes the ocean floor?
The ocean floor is made up of various geological features, including mid-ocean ridges, deep-sea trenches, and abyssal plains. It is also home to diverse ecosystems, such as hydrothermal vents and coral reefs, and is covered with sediment derived from land and marine sources. The ocean floor plays a crucial role in regulating Earth's climate and supporting marine life.
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.
What term describes organisms that live in or in the ocean floor?
Benthos
How can the composition of of the ocean floor be determined?
Ocean topography has been determined through sonar detection.
What describes the ocean floor?
It is varied and includes features such as submarine canyons, atolls, and mid-ocean ridges.
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.

Why do scientists look to the ocean floor to research the mantle?
Scientists study the ocean floor to understand the mantle because it provides access to the boundary between the Earth's crust and mantle. This boundary, known as the Moho, holds key information about the composition and behavior of the mantle, helping scientists understand processes like plate tectonics and mantle convection that shape the Earth's surface.
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
What is the topography of the ocean floor?
The topography of the ocean floor
