What is similar about mold and cast fossils and petrified wood?
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
Which fossil type could contain preserved parts of an organism?
mold fosssil
What are 3 examples of body fossil?
oil coal natural gas
What are cast fossils?
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.
Which type of fossil is formed when an entire organism is filled with materials such as mud or clay and then hardens the entire organism and the filling?
The fossil that is formed when an organism is buried in sediment and hardens into rock is called a cast fossil, in which the empty space serves as a mold.

What are the similarities between original replaced remain fossils and cast and mold fossils?
All are indicative of the size and shape and possible habitat of the original organism.
What is mold and cast fossils?
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.
How is fossils mold different from a fossil cast?
a mold is what you pour materials into to make a cast
Which fossil type could contain preserved parts of an organism?
mold fosssil
Define fossils and explain how fossil are made?
Fossils are depositions of dead animal imprints and/or bones. When an animal or plant dies, its skin rots away, leaving behind the bone or imprint.
Describe what fossils are and list three different kinds?
Fosssils are the preserved remains or traces of animals , plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record.Types:-mold fossils (a fossilized impression made in the substrate - a negative image of the organism)cast fossils (formed when a mold is filled in)trace fossils = ichnofossils (fossilized nests, gastroliths, burrows, footprints, etc.)true form fossils (fossils of the actual animal or animal part).
What are mold and cast fossils?
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.
Why cast fossil and mold fossil found together?
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
What are five different type of fossils?
Imprint fossils, Mineralized fossils, frozen fossils, fossils in amber, and cast fossils.
What are casts and mold?
a mold is an impression of an organism. a cast is a mold filled with sediment
Are mold and cast fossil the same thing?
There are mold and cast fossils in many local creeks, streams, and/or rivers.If the original organism dissolves or decays, leaving a hollow in the rock, that is a mold.If the mold fills up with sediment which gradually hardens into the shape of the original organism, then that is a cast.Casts are copies of fossilized plants or animals. Molds are hollow impressions of the fossil.Its a Fossil.
