It's either Fossil or a Trace Fossil.
A Petrified fossil dissolved minerals replace and remains of an organism and then harden to form rock.
Igneous Rock.
Space is filled with the unknown and the mysterious. they say large bodies of gas biulds up in one place and begiens to harden and forms a great mass known as a stars.
James harden is way better than Stephen curry
It has to harden

permineralization
permineralization
Permineralization is the process of fossilization where mainly water mineral deposits take the form of the organism. The minerals harden with time and pressure from over laying deposits turning into rock. Petrification happens when silica binds with celulose of a plant and turns into stone often retaining the microstructure of the plant.
lava helps harden with stone and minerals grow it
Minerals like calcium and phosphorus :)
yes with the minerals and time
Igneous Rock.
to harden and make things and drilling tools
One form of fossil forms when an organism dies and its body is covered by layers of sediment. As time passes, the organism itself, particularly when composed primarily of softer materials, is eroded and carried away, leaving a negative imprint of its body. This type of fossil is called a mold. A cast fossil forms when a mold fossil is filled with some form of mineral, usually through the seepage of water depositing the minerals within the mold. In time, the mold is filled and the materials deposited harden, creating a replica of the original fossil. This is called a cast fossil.
you can melt sand in very high temperatures, mix it with certain minerals, then it will harden into glass.
