Undisturbed seafloor sediments will carry a history of what has transpired there, much like glacial ice or peat bogs. Some interesting and potentially valuable mineral deposits are also found on the seafloor, eg. manganese nodules, metals from black smokers, and of course, deep in the rock, oil.

Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
What are three different types of marine sediments?
limestone, chalk, siltstone
What are the two types of biogenous sediments?
Two types of biogenous sediments are calcareous ooze and siliceous ooze.
What type of soil is in oceans biomes?
The ocean floor is composed of three different types of soil, known as pelagic sediments or marine sediments. They include calcareous ooze, red clay and siliceous ooze.
What types of sediments are in solids?
All sediments are solids by their very nature. By definition, a sediment is the solid material that settles out of a liquid suspension.
Explain how ocean-floor rocks and sediments are evidence of seafloor spreading?
The seafloor rocks vary in different places. Rock samples near ocean ridges are younger than rocks at deep sea trenches
Microcrystalline quartz formed by recrystallization of silicaeous oozes in seafloor sediments?
Chert.
What is the usual amount of seafloor sediments in a given location?
500 to 1000 meters
Is a disadvantage of dredging that this sampling method does not preserve the layers of the seafloor sediments?
True.
What is the main geographic feature that distinguishes different types of landforms?
sediments
What are three different types of marine sediments?
limestone, chalk, siltstone
How does the age of seafloor sediments change the increasing distance from the ocean ridge?
age increases
What are the three types of the ocean floor sediments?
The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.
Are sediments?
Sediments in geology are solid fragments of inorganic or organic material that come from the weathering of rock or biological processes and are carried and deposited by wind, water, or ice. Sediments are types of rock that are formed by the deposition of material from the Earth's surface. There are different types of sediments rocks.
What are the three types of ocean sediments?
The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.
How does the age of seafloor sediments change with increasing distance from the ocean ridge?
Age of seafloor rock and sediment increases with distance from the oceanic ridges.
Most oceanic gas hydrates form when?
bacteria break down organic matter in seafloor sediments
