GEOLOGY

Detailed explanation-1: -Ocean sediments are incredibly important for marine wildlife, as they provide a home for a diverse array of marine invertebrates and fish, as well as providing a rich foraging ground for larger predators to feed on.

Detailed explanation-2: -Most deep ocean sediments are silt and mud. Most sediments form as rocks are broken down into smaller particles such as sand and clay.

Detailed explanation-3: -On the seafloor, sediments are thinnest near spreading centers (young seafloor) and thicker away from the ridge, where the seafloor is older and has more time to accumulate. Sediments are also much thickest near continents.

Detailed explanation-4: -Deep-sea sediments can reveal much about the last 200 million years of Earth history, including seafloor spreading, the history of ocean life, the behaviour of Earth’s magnetic field, and the changes in the ocean currents and climate.
