Shale Rock
When coral animals die do their skeletons fall to the sea floor?
When coral animals die their skeletons do indeed fall to the sea floor. This is the only place where they can go.
When coral animals die their skeletons fall to the sea floor.?
Yes, they do.
Ooze on the ocean floor is formed from the remains of which of these?
Ooze on the ocean floor is formed from the remains of marine organisms like phytoplankton and zooplankton, as well as shells and skeletons of marine animals. Over time, these organic materials accumulate and form sediment on the ocean floor.
Which type of material does biogenous sediment form?
Two types of biogenous sediments are calcareous ooze and siliceous ooze.
Do skeletons exist on the ocean floor?
The ocean floor sediment contains unfathomable numbers of marine organism skeletons.
Where are Shells found?
Shells are found in various aquatic environments such as oceans, rivers, lakes, and seas. They can be found on sandy beaches, on the ocean floor, and attached to rocks or coral reefs. Shells are the external skeletons of mollusks, which are a type of invertebrate animal.
Under what conditions is limestone formed?
Many living things, including coral, clams, oysters, and snails, have shells or skeletons made of calcite. When these animals die, their shells pile up a sediment on the ocean floor. Over millions of years, these layers of sediment can grow to a depth of hundreds of meters. Slowly, the pressure of waveringly layers compacts the sediment .Some of the shells dissolve, forming a solution of calcite that seeps into the spaces between the shell fragments. Later, the dissolved material comes out of solution, forming calcite. The calcite cements the shell particles together, forming limestone.
Biogenous sediments are shells and skeletons of marine animals and algae what are two examples of this?
Two examples of biogenous sediments are foraminifera shells and diatom skeletons. These materials accumulate on the ocean floor over time and contribute to the formation of sedimentary rocks like limestone.
What is limestone and chert?
Limestone is a boigenic rock. It is formed as a byproduct of living things, frequently it is made from the calcareous skeletons of living creatures. If we take the Chalk as a limestone, this was made in a warm shallow sea from the shells of microscopic plankton as they died and sank to the sea floor. However along with the calcareous shells, there were also shells of diatomic plankton which are made out of silicon dioxide (quartz). After deposition as the chalk was compacted by the overlying sediments that were laid down on top of it and it became buried, the water it contained became heated and the skeletons of the silicious diatoms dissolved in the water and then were redeposited as layers of "Chert" or "Flint" in the Chalk.
