Large flat areas of the ocean floor are called abyssal plains. These regions are typically covered in thick layers of fine sediment and are among the flattest, most featureless parts of the ocean floor. Abyssal plains are found at depths between 3,000 and 6,000 meters.
narrower than those of the Atlantic and are not covered with thick layers of sediment
the crust will cool to form metamorphic rock
The mantle
Large areas of sea floor are covered with thick layers of sediment containing calcium due to the accumulation of calcium carbonate shells and skeletons from marine organisms over time. This process, known as biomineralization, contributes to the formation of limestone and other calcium-rich sediments.
Adjacent seas were covered by shallow oceans. Over a period of millions of years the remains of marine animals and plants fell to the sea floor, they accumulated into thick layers and eventually were covered by layers of sand and silt. Over time, the immense weight of all of these layers compressed the lower layers into sedimentary rock. Bacterial actions, heat, and pressure converted the remains of the animals and plants into oil. The middle east was one covered in ocean, hence why they have so much sand, there are even places in the desert where you can go shark tooth hunting.
Antartica has no agriculture, the ground is covered with thick layers of ice.
The forest floor was covered with thick vegetation.
the thickest accumulation of sediment on the ocean floor is at the CONTINENTAL SLOPES AND RISES. :)
A deep-sea canyon or a submarine fan would most likely be covered with thick turbidite layers. Turbidites are sediment layers formed by underwater landslides, where sediment-rich currents flow down continental slopes and deposit sediment in deep-sea environments. These areas are known for accumulating thick sequences of turbidites over time.
The thick slime on the ocean floor is commonly referred to as marine mucilage. Marine mucilage is a gelatinous substance formed by the aggregation of organic matter in seawater, and it can harm marine life by depleting oxygen levels as it decomposes.
Thick evaporite layers can form in a restricted ocean basin through a process called repeated cycles of evaporation and precipitation. As water evaporates, minerals become more concentrated, eventually reaching a point where they can precipitate out to form thick evaporite layers. This process can occur over long periods of time and with multiple cycles of evaporation, leading to the accumulation of thick evaporite deposits.
