First, a thin layer of sediment hardens and forms a mold. Then, what is known as a cast is when a new layer of sediment fills in the mold breaking down the creature/ animal/fossil.
cast.
A mold and cast fossil is and exact stone replica of an organism but it is formed like this. The first layer of sediment hardens and forms a mold. then a new layer of sediment fills in the mold and hardens. That is the cast.
when fossile mould is filled it forms the model of the fossile
It is a cast fossil.
A mold and cast fossil is and exact stone replica of an organism but it is formed like this. The first layer of sediment hardens and forms a mold. then a new layer of sediment fills in the mold and hardens. That is the cast.
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.
no
Mold is like cast in being a type of fossil .
a mold is what you pour materials into to make a cast
A fossil mold is formed by the impression left in rock by the remains of an organism. A cast fossil occurs when the mold is filled in by precipitating minerals.
There are four types of fossils that can be found. These are true fossils, mold fossils, trace fossils and cast fossils.
Both copy the shape of its ancient organisms.a MOLD is a hollow area in sediment in the shape of an organism or part of an organism.a mold forms when the hars part of the organism,such as a shell,is buried in sediment.Later, water carrys dissolved minerals and sediment there,the result is a cast. A CAST is a solid copy of the shapes of organisms.a cats is the opposite of a mold.both mold and cast preserved details of the animals structure
it is called a MOLD
