How diatomaceous earth is formed?

Solution:

• Diatoms are the golden brown photosynthetic protists.they occur in all aquatic and moist terrestrial habitats
• Diatoms may show a gliding type of movement with the help of mucilage.
• They contain the cell wall which is made up of siliceous material which does not decay.so they are  responsible for formation of diatomite.
• Diatomaceous earth is used for treatment of health issues like high cholesterol, constipation, skin problem and bone issues.

Final Answer:

The siliceous cell walls of diatoms are indestructible which do not decay easily. They were collected over millions of years on the seafloor or pile up at the bottom of water reservoirs and form big heaps called diatomite or diatomaceous earth . it may extend for several hundred metres in certain areas where the same can be mined.
