Along which coast is Thorium found in abundance?
Calcareous ooze
Sediments form during the erosion and weathering processes that break down rocks into smaller particles. These sediments may then undergo deposition and compaction to form sedimentary rocks in the rock cycle.
Sedimentary rocks form when sediments such as sand, mud, and organic material are compacted and cemented together over time. These sediments can accumulate in various environments such as rivers, lakes, oceans, and even on land. After burial and compaction, the sediments undergo lithification to become sedimentary rocks.

minerals that crystalize directly from ocean waters
The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.
Hydrogenous sediments are formed when minerals precipitate from the ocean, or they can be formed when minerals in the water react with older sediments.
The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.
Ocean floor sediments primarily consist of three types: terrigenous, biogenous, and hydrogenous sediments. Terrigenous sediments originate from land, including clays and silts brought by rivers and wind. Biogenous sediments are formed from the remains of marine organisms, such as foraminifera and diatoms, while hydrogenous sediments precipitate directly from seawater, including minerals like manganese nodules. Additionally, cosmogenous sediments, derived from extraterrestrial sources like meteorites, are also present but in smaller amounts.

Manganese nodules are polymetallic concretions found on the ocean floor and are formed through a slow process of precipitation and accumulation of manganese and other metals. They are a type of sediment known as hydrogenous sediment, as they form directly from seawater and not from the breakdown of rocks or organic materials.
Lithogenous sediment is not biogenous; it originates from the erosion of rocks on land. Biogenous sediments come from the remains of living organisms, such as shells and coral. Hydrogenous sediments are chemical precipitates that form in seawater.
The three types of ocean floor sediments are terrigenous (derived from land sources), biogenous (derived from biological organisms), and hydrogenous (derived from chemical processes in seawater).
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.
Terrigenous sediments, which originate from land and are composed of materials like sand, silt, and clay. Biogenous sediments, made up of the remains of marine organisms such as shells, coral, and diatoms. Hydrogenous sediments, formed from minerals that precipitate directly from seawater and include materials like manganese nodules and metal sulfides.
