The ocean basin floor is everywhere covered by sediments of different types and origins.

Distribution of sediment types on the ocean floor.

Another classification of ocean floor sediments is by the size of the individual grain. This is a more unusual way to categorize ocean floor sediments. The amount of organic matter preserved in the sediment depends on how much is produced and the preservation efficiency. On average in the ocean only about 1 of the organic matter that sinks to the bottom of the ocean is preserved.

Sandstone is an example of which of the following sediment types. Sediment thickness in the oceans averages about 450 metres 1 500 feet. Prior knowledge on sea floor sediments is explored in part 1. Identify the origins of different types of sediment 2.

Clay less than or equal to 4 micrometer silt 4 to 62 micrometer sand 62 micrometer to 2 millimeter and more than 2 millimeter such. Terrigenous sediment is derived from land and usually deposited on the continental shelf continental rise and abyssal plain. In parts 2 3 students observe and describe the physical characteristics of sediments cores and determine the composition using smear slide data and a decision tree. Distribution of sediment throughout the ocean.

The size is from the smallest to largest these are. Biogenous sediment cosmogenous sediment hydrogenous sediment. Cosmogenous sediments could potentially end up in any part of the ocean but they accumulate in such small abundances that they are overwhelmed by other sediment types and thus are not dominant in any location. They are useful for determining the distribution of ancient dinosaurs.

The area has low biological productivity and the ccd is at 4500 m depth. 12 6 sediment distribution now that we have an understanding of the types of sediments found in the ocean we can turn our attention to the processes that cause different types of sediments to dominate in different locations. The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover. Figure pageindex 1 shows the distribution of the major types of sediment on the ocean floor.

Sediment accumulation will depend on the the amount of material coming from the source the distance from the source the amount of time that sediment has had to. Is not a random arrangement of these different sediment types. Ocean basin ocean basin deep sea sediments. In part 4 students develop a map showing the distribution of the primary marine sediment types of the pacific and.

Analyze and describe the distribution of sediment types throughout the ocean lesson contents 1. Define a deep sea sediment known as ooze and differentiate types of ooze based on composition 3. Some of these organic. It is further contoured by strong currents along the continental rise.

Sedimentary organic carbon preservation there are several controls that affect the org c distribution in in sediments. You take a sediment sample from the ocean floor at a depth of 5500 m.
