The ocean floor is primarily composed of basaltic rock, which forms from solidified lava from underwater volcanic activity. It also includes sediment deposits, such as sand, clay, and dead marine organisms, which accumulate over time. The ocean floor features underwater landforms like trenches, ridges, and seamounts, shaped by tectonic activity and erosion.

β 13y agoThe ocean floor is composed of basaltic rocks. Very mafic (dark) in color. It is thinner yet heavier than continental rock.

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.
Sea Floor Spreading
No. The newest ocean floor is at the mid-ocean ridge.
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.
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.
The ocean floor generally consists of basalt cooled from magma, and the overlying layers of sediment, both inorganic and organic.

Ocean topography has been determined through sonar detection.
Benthos
It is varied and includes features such as submarine canyons, atolls, and mid-ocean ridges.

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.

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.
