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

Bones
Describe the four types of fossils?
Types of fossilsUsually the remains of dead plants and animals quickly decay and aredestroyed. When the remains are protected from scavengers andmicro-organisms, however, they can become fossilized.If a carcass is in water and sinks to the bottom, the body can beburied by sediment. Soft parts, such as skin, muscle, or organs decayrapidly and are rarely found as fossils. The hard parts (bones, shells,or teeth) may be altered to become fossilized remains. When waterpenetrates the bones of a dead animal, the water dissolves the calciumcarbonate in the bones. A deposit of another very hard mineral, silica(quartz) remains, turning the bones into a petrified (rock-like) substance.When an organism is buried under many layers of sediment,pressure and heat may build up, leaving a thin film of carbon residueon rock surfaces. The residue forms an outline of the organism. Theoutline is called a carbonaceous film.
What are 3 examples of body fossil?
oil coal natural gas
How are cast fossils formed?
An object that was repllaced by rock so the fossil is now 3D.
What are five different type of fossils?
Imprint fossils, Mineralized fossils, frozen fossils, fossils in amber, and cast fossils.
What are Two most common types of fossils?
There are a variety of types of fossils. These include cast fossils, mold fossils, petrified wood, as well as fossil fuels.

What are the types of fossils?
molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.
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.
How is fossils mold different from a fossil cast?
a mold is what you pour materials into to make a cast
What fossils offer information on the activity and physiology of the creature that made them?
Probably a trace fossil; evidences of an organisms existence, without the body. Trace fossils include footprints, feces, burrow marks, and chemical signatures.
Which part of an organism is preserved in cast and mold fossils?
Bones
What are the difference types of fossils?
Mold fossils- an empty space is left when an organism is buried in sedimentary and it decays.Cast fossils- Minerals in rocks fill space left by a decayed organism.(replica)Trace fossils- Markings left by an animal. (footprints, trail, or burrow)Petrified fossils- Minerals penetrate and replace all or part of an organism.Imprint fossils

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.
Where are mold fossils located?
mold fossils are either located near water or cliffs.
