They are like little fish fosils for an example if you find a limestone rock look at it and you will see bones
The only rock that can form in this way is limestone formed from calcium carbonate concentrated in shells and exoskeletons like corals. The rock itself comes from sediment rich in these materials after the animals' deaths.
Yes, but this is not the major source. Marine corals are the most abundant source.
My sheit!
glass is a prime example-- made of sand. Concrete is another. I disagree. Concrete is made by mixing cement and various aggregates, such as sand, pebbles, gravel, or shale, with water. Cement is a mixture of clay and limestone. Limestone is a sedimentary rock consisting predominantly of calcium carbonate, which is formed from the skeletons of marine microorganisms and coral. Concrete is made from once living things.
A printer is made from plastic and metal, and is a non-living thing.
living things are made of germs
a living thing is that can eat, breath,move.smell.
Dolphin skeletons are not made of bones like most mammals. Instead their skeleton is made of a tough, flexible tissue called cartilage. It is the same thing that human ears are made of.
by cell
The first classification of the living thing was made by Aristotle.
to be living it does. Everything is made up of matter, but living things are made up of cells
The Phantom stole from the musical theater in Paris is how he made the living. When he was away from the theater, he worked as circus freak, the Living Skeleton for Gypsies.
