Ocean basin ocean basin deep sea sediments.

Distribution of sediment types on the ocean floor.

The ocean basin floor is everywhere covered by sediments of different types and origins. Sediment thickness in the oceans averages about 450 metres 1 500 feet. This is a more unusual way to categorize ocean floor sediments. On average in the ocean only about 1 of the organic matter that sinks to the bottom of the ocean is preserved.

Distribution of sediment throughout the ocean. 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. You take a sediment sample from the ocean floor at a depth of 5500 m. Biogenous sediment cosmogenous sediment hydrogenous sediment.

Oceanographers have painstakingly mapped the distribution of sediment around the globe and have learned that at any given location the sediments provide important information regarding the history of the ocean as well as the overall state of climate on the. Figure pageindex 1 shows the distribution of the major types of sediment on the ocean floor. 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. Some of these organic.

In part 4 students develop a map showing the distribution of the primary marine sediment types of the pacific and. Identify the origins of different types of sediment 2. It is further contoured by strong currents along the continental rise. The amount of organic matter preserved in the sediment depends on how much is produced and the preservation efficiency.

Pelagic sediment is composed of clay particles and microskeletons of marine organisms that settle slowly to the ocean floor. They are useful for determining the distribution of ancient dinosaurs. Sedimentary organic carbon preservation there are several controls that affect the org c distribution in in sediments. The area has low biological productivity and the ccd is at 4500 m depth.

Analyze and describe the distribution of sediment types throughout the ocean lesson contents 1. Lesson objectives earth science students will. The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover. 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.

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. Sandstone is an example of which of the following sediment types. The size is from the smallest to largest these are. Another classification of ocean floor sediments is by the size of the individual grain.

Is not a random arrangement of these different sediment types. Prior knowledge on sea floor sediments is explored in part 1.
