When an organism dies and over time is buried by sediment what happens to the soft parts of the organism?
For more than 99% of organisms the burial is slow enough that the soft parts either rot or are eaten by scavengers. This also often scatters or damages the bones.
For the rest the soft parts can become mineralized and become part of the fossil. However they may only appear as a dark discoloration of a thin layer of rock between the fossilized bones.
What else can I help you with?
Fossils are formed in rocks when the blank body parts of an organism get buried in blank and are preserved when it turns to blank?
Fossils are formed in rocks when the hard body parts of an organism get buried in sediment and are preserved when it turns to rock.
Does a mold form when hard parts of an organism buried by sediments Are gradually dissolved?
Yes, a mold forms when the hard parts of an organism, such as bones or shells, are buried by sediments and gradually dissolve over time. This process leaves behind a cavity or impression in the sediment that reflects the shape of the original organism. Molds are important in paleontology as they provide insights into the morphology of extinct species. The opposite process, where minerals fill the mold, creates a cast of the organism.
An organism becomes a fossil after it what?
An organism becomes a fossil after it is buried by sediment and undergoes a process called fossilization. This involves the deposition of minerals that replace the organic material of the organism, preserving its structure. Over millions of years, the remains may become rocks or minerals that retain a record of the organism.
What must usually happen in order for a dead organism to be preserved as a fossil?
B. The organism must be buried in sediment soon after it dies.C - the organism must go through a process of petrificationNeededMoist sediment or soilorganism trapped, dieslack of anything disturbing that areamoistness ; warmth ; heat to break down additional layeringpressure from more layers on toplengthy amount of time (millions of years)
Which type of fossil forms when an organisms hard parts dissolve and leave a cavity that later fills with sedim?
A mold fossil forms when an organism's hard parts dissolve and leave a cavity that later fills with sediment, creating a replica of the organism's shape.

Fossils are formed in rocks when the hard body parts of an organism get buried in sediment and are preserved when it turns to rock.
This type of fossil is formed when an organism is buried in sediment which hardens into rock. After the soft parts of the animal rot away a cavity remains?

How is carbonaceous is form?
A fossil is formed when the dead organism is buried in rock or parts of rock called sediments. The more sediment that builds up on plants or animals the more pressure and heat it is shown too,then circumstances force gas and liquid from the organism. A residue is left from the carbon which forms the outline of the body. This results in carbonaceous film.
If an organism has hard parts it stands a good chance of being fossilized if they are?
slowly buried by sedments {: -DR. SCRAPOLOTS
What is the two conditions that help the process of fossilization?
Fossilization is aided by rapid burial of remains in sediment, which prevents decomposition, and the presence of minerals in the surrounding environment that gradually replace the organic matter of the organism, creating a fossil.
What conditions are necessary for fossil's to form?
Hard parts/quick burial
This type of fossil is formed when an organism is buried in sediment which hardens into rock After the soft parts of the animal rot away a cavity remains?
The type of fossil being described is a mold fossil. These fossils preserve the external shape of an organism by filling in the cavity left behind after the original organism decays. Mold fossils provide important insights into the shape and size of ancient organisms.
How do parts of living things become fossilized?
When an organism dies, it can become buried in sediment which helps protect it from decay. Over time, minerals from the surrounding environment can seep into the organism's tissues, gradually replacing them and forming a fossil. The process of fossilization can take millions of years.
Which type of fossil forms when an organisms hard parts dissolve and leave a cavity that later fills with sedim?
A mold fossil forms when an organism's hard parts dissolve and leave a cavity that later fills with sediment, creating a replica of the organism's shape.
Do all rocks contain fossils explain the conditions necessary for fossils to form?
No, not all rocks contain fossils. Fossils form when the remains of plants or animals are buried quickly by sediment, protecting them from decay and allowing for the preservation of the organism's shape. The presence of water and minerals in the surrounding environment helps in the fossilization process by replacing the organic material with minerals over time.
