These sediments are found in a very small amount and generally constitute 0.5 to 1 % of the total ocean sediments. These high impact collisions eject particles into the atmosphere that eventually settle back down to Earth and contribute to … We classify marine sediments by their source. Origin, Composition and Distribution (protozoans) (Figure 12.3.1). Biogenous sediments come from organisms like plankton when their exoskeletons break down. Cosmogenous sediment is sediment originating from objects from space. Hydrogenous sediments are sediments directly precipitated from water. Like spherules, meteor debris is mostly silica or iron and nickel. Thus, modern science determines four basic types of sediments. Cosmogenous sediments originated from outer space. These kinds of sediments are carried to earth on meteorites or asteroids. D. terrigenous sediments.

Cosmogenous sediment is sediment originating from objects from space. This material comes from several different sources and is highly variable in composition, depending on proximity to a continent, water depth, ocean currents, biological activity, and climate. Lithogenous sediments come from land via rivers, ice, wind and other processes. Lithogenous sediment tends to dominate near the edges of continents and islands Do you think sediment is uniformly distributed throughout the ocean? Hydrogenous sediments – they are formed from the precipitation of dissolved minerals from water mainly by bacteria.
