Without rapid burial decay will take place and you will not be left with a fossil. In the same way coalification requires rapid burial of organic material. A good example of this is spirit lake in Washington state.

Is a fossil formed when an organism buried in sediment dissolves called?
When a hard part of an organism buried in sediment dissolves an leaves an empty space it is called a mold.
What must form first for a cast to be made?
📷 Organisms buried in sediment slowly decompose, leaving a cavity that contains an exact imprint of the organisms' shape and size. When this hollow space fills with material, this material takes the shape of the mold, forming a cast.
What fossil formed when an organism buried in sediment dissolves leaving a hollow are?
The answer is Mold
Minerals seeping into an organisms remains form what?
Minerals seeping into an organisms remains form fossils. sediment
Remains of animals and plants were buried quickly in sediment during floods?
Such remains are known as fossils if the sediment is changed over eons into a sedimentary rock.
Which is the first step in the process during the formation of molded fossils?
Organisms are buried under sediment.
What is another name for nutrient cycles in ecosystems?
The dead organic matter are an example of nutrient cycle and can sometimes be buried under sediment, rendering the carbon unavailable to living organisms.
What are some example of cycles?
The dead organic matter are an example of nutrient cycle and can sometimes be buried under sediment, rendering the carbon unavailable to living organisms.
What make fossils unique?
something that dies then u have to have it buried in sediment rock and pressure no heat then millions of years
What does coral become when it is buried by sediment?
a potato
Is a fossil formed when an organism buried in sediment dissolves called?
When a hard part of an organism buried in sediment dissolves an leaves an empty space it is called a mold.
How does a cast fossil form?
When the animal dies its skeleton settles on the sea floor and is buried by sediment. that thickens and begins to turn to stone. The skeleton dissolves and a mold is formed. Minerals crystallize inside the mold and the cast is formed.
What makes a fossil form?
It gets buried in sediment
How do sedimentary rock embed organisms?
When organisms died in a river or stream of some sort, they are covered in a layer of sediment, as time gos by the sediment hardens and is covered by another layer of sediment and so on.
Does coal represent sediment?
No coral is NOT sediment. Coral SAND is a sediment but the coral itself is a living organism - if buried and lithified, the coral becomes a fossil.
Cavity in rock made when an organism decayed?
A cavity in the ground where organisms can be buried is called a hole. If sediment fills this hole the organism may become fossilized.
What is a bioturbation?
A bioturbator is an organism which carries out bioturbation - the mixing of soil or sediment by living organisms.
