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

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 the five types of fossils that can be found in rock?
Five types of fossils found in rocks are petrified fossils (minerals replace organic matter), mold fossils (imprint of an organism), cast fossils (mold filled with minerals), carbon films (thin layer of carbon residue), and trace fossils (evidence of organism's activity).
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.
What are Cast fossils mold fossils petrified fossils trace fossils carbon fossils and preserved fossils?
Cast fossils: Formed when minerals fill a mold left by a decayed organism. Mold fossils: Created when an organism's remains leave an impression in sediment that hardens into rock. Petrified fossils: Organic material replaced by minerals over time, forming a rock-like replica. Trace fossils: Evidence of an organism's activity (e.g., footprints or burrows) preserved in sedimentary rock. Carbon fossils: Organisms preserved in carbon-rich environments, like coal or oil deposits. Preserved fossils: Organisms remain intact or partially intact due to exceptional preservation conditions.
What are the 5 types of fossil?
the 5 types of fossils are: 1.petrified fossil 2.carbon films 3.trace fossil 4.perserved remains 5.mold and cast
What are 5 kinds of fossils?
Petrified fossils: where organic material is replaced by minerals. Mold fossils: where the shape of an organism is preserved in sediment. Cast fossils: formed when a mold fills with minerals, creating a replica of the organism. Trace fossils: records of biological activity, like footprints or burrows. Amber fossils: organisms preserved in hardened tree resin.
What are the names of the five types of fossils?
The 5 types of fossils are ...Imprint Fossils- an organism leaving an imprint on sediment that later hardens into rock.Mineralization Fossils- when minerals replace wood or bone to create a piece of petrified wood or a mineralization bone fossilsFrozen Fossils- when something like an animal gets taped in ice and remains their frozenCast Fossils- when it fills up a hollow moldfossils in amber- when an insect gets stuck in amber
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
