What are casts and mold?
a mold is an impression of an organism. a cast is a mold filled with sediment
Is a cavity in the ground where an organism was buried If this cavity is filled in with sediment it can form a cst?
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 is cast fossil?
A cast fossil is formed when a mold fossil is filled in with minerals or sediments, creating a replica of the original organism. The mold is created when an organism decays or is buried in sediment, leaving an impression behind. Cast fossils can provide valuable information about the shape and structure of the original organism.
If an entire organism dissolves away the resulting cavity is?
The resulting cavity is typically referred to as a cast or mold, depending on whether the dissolved organism was filled with sediment (mold) or left an empty space (cast). These cavities are important for understanding fossilization processes and can preserve the morphology of the original organism.
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.
Is a fossil formed when an organism buried in sediment dissolves called?
No, a fossil formed when an organism buried in sediment dissolves is called a mold fossil. It is created when the organic material of the organism dissolves, leaving behind an impression or cavity in the sediment that hardens into rock.
Molds filled with sediments sometimes produce?
Molds and casts may be produced when sediments fill molds left by decayed organisms.
What is when remains of an organism dissolve and leave a cavity?
When remains of an organism dissolve and leave a cavity, it can result in the formation of a fossil mold. This mold can then be filled with minerals or sediment, creating a cast fossil, which preserves the shape of the original organism. Both mold and cast fossils provide valuable information about the organism's characteristics and environment.
What are five ways fossils can form?
Preservation in sedimentary rock: The organism's remains are buried in sediment and mineralized over time. Casts and molds: The organism's remains decay, leaving an impression in the sediment that is later filled with minerals. Carbonization: The organism's remains are compressed, leaving behind a thin film of carbon. Freezing or desiccation: The organism is preserved through freezing or drying out quickly. Amber preservation: The organism becomes trapped in tree resin, preserving it over time.
