Diatoms are microscopic algae that have silica shells, or frustules, that are resistant to decomposition. When diatoms die, their shells sink to the ocean floor where they accumulate over time in sediments, forming diatomaceous earth. This accumulation is due to their abundance in aquatic environments and slow degradation rate, making them a common component of ocean-floor sediments.

When sediments are disturbed the oldest layers are found at the?
In disturbed sediments without layers, the relative age of the sediments would be unknown.
How are neritic sediments different form pelagic sediments?
Neritic sediments are found in shallow water close to the coast, while pelagic sediments are found in deep open ocean areas. Neritic sediments tend to be coarser and more influenced by terrestrial input, while pelagic sediments are finer and accumulate slowly over time.
What are the different types of seafloor sediments?
The main types of seafloor sediments are terrigenous (from land sources), biogenous (from marine organisms), hydrogenous (formed in place from seawater), and cosmogenous (from outer space). Terrigenous sediments are the most common and include materials like sand, silt, and clay. Biogenous sediments are composed of the shells and skeletons of marine organisms, while hydrogenous sediments are minerals that precipitate directly from seawater. Cosmogenous sediments come from extraterrestrial sources like meteorites.
What types of sediments are in solids?
Common types of sediments found in solids include sand, silt, clay, and gravel. These sediments can vary in size and composition, with sand being larger particles and clay being fine particles. Sediments can also contain organic materials and minerals.
What are examples of ice age sediments?
Examples of ice age sediments include till, glacial erratic rocks, moraines, and outwash plains. These sediments were deposited by glaciers during the last ice age and can be found in regions that were once covered by ice sheets.
Where is the diatom found?
Mostly in marine photic zones .
Is Lactobacillus Diatom or Euglena?
Lactobacillus is a bacterium, not a diatom or euglena. It is a type of lactic acid bacteria that is commonly found in the digestive system and is also used in the fermentation of foods such as yogurt.
Is diatom an organism?
Yes, a diatom is a single celled organism. They are a major group of algae and usually found in all water environments.
What is the habitat of a diatom?
Diatoms are usually found in marine areas like oceans.
Why did the mucrospirifer fossil only found in sedimentary rocks?
Mucrospirifer fossils are found in sedimentary rocks because these rocks are formed from the accumulation of sediments, which can preserve fossils over time. The organisms that formed mucrospirifer shells lived in marine environments where their shells could be buried and preserved in the sediment. Sedimentary rocks provide the ideal conditions for fossilization to occur due to the gradual accumulation and compaction of sediments over millions of years.
When sediments are disturbed the oldest layers are found at the?
In disturbed sediments without layers, the relative age of the sediments would be unknown.
What are shells?
shells are found near the shore line
What are found in the electron shells or clouds?
Electrons are found in the shells and clouds.
What sediments are found in potting soil?
Sand.
Pictures of a diatom?
diatoms are tinny substances found in water that are living
How many sea shells did sally find?
Sally found 109381 sea shells on the sea shore.
Where are conch shells found?
Conch shells are found in the Florida Keys which are a group of more than1700 islands
