FranThe 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.

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.
