Which type fossil is formed when an organism gets trapped in a developing rock layer and then decays away leaving an imprint of what the organism looked like?
A mold is a fossil created by the encasement of an organism in rock, where the organism decays away after solidification of the encasing structure, leaving behind an impression of the original organism. An additional stage is a cast, where the mold is back filled by sedements to create a solid model of the original organism.

When a insect is trapped in amber it is an example of what type of fossil?
Many insects get trapped in amber. Amber is fossilized tree resin.
What remains trapped in rock may form a?
Mold cast petroleum
How long can bees survive without water?
If you have trapped and bee and made food and water inaccessible, it would take about 48 hours to die. If he is not trapped, he will go search for food and water to prevent death.
Insects become fossils if they are trapped in tree sap that hardens to become?
amber
Why is wadding or filling a good insulater?
Wadding, or filling, will trap pockets of air. As the air is trapped, it cannot convect heat so easily, and it is also more difficult for heat to be conducted. So, trapped air is a good insulator.
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.
How long have the la brea Asphalt deposits preserve trapped organism?
It has preserved trapped organisms for at least 38,000years.
Is it true that fossils occur only when an organism dies and the remains are trapped between layers of rock?
False
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)
What is called when organisms are trapped in sedimentary rock?
when an organism is trapped in sedimentary rock, it will die and the organism will slowly decay, but it won't decay altogether and you get a fossil. the older the fossil is the lower down it will be in a sedimentary layer. that's called superposition...
Over time what type of fossil is formed when thin objects are trapped in mud?
Thin objects trapped in mud can form trace fossils, such as worm burrows or footprints, which show evidence of the organism's activity rather than the organism itself. These trace fossils can provide important information about the behavior and ecology of ancient organisms.
What are two way an organism can become a fossil without being buried in sediment?
An organism can become a fossil through natural mummification, where it dries out quickly and is preserved in a dry environment. Another way is through freezing, where the organism becomes frozen in ice and is preserved in a state of suspended animation.
When are fossils trapped in rocks?
Fossils are typically trapped in sedimentary rocks when the remains of an organism are buried by layers of sediment over time. The soft tissues decompose, leaving behind hard parts like bones or shells, which can then become fossilized through processes like mineral replacement or compression. The age of the fossils can be determined by dating the rocks in which they are found.
What conditions make impression fossils form?
The best preservation and fossilization of fossils occurs in calm,aquatic environment.Exceptional preservation also occurs in fine-grained sediments in absence of oxygen.Both this environmental conditions allow easier formation of impression of trapped fossil plant of animal.Impression mainly form from fossils plants and animals that are later decomposed leaving their image shape on the country rock at the time.CONDITIONSWet conditionfine grained country rockaerobic condition that favor decomposition of the fossils leaving behind impression
Why is sea water trapped in huge shallow pools and not small deep pools?
The reason seawater is trapped in huge shallow pools in stead of small deep ones is beacause huge shallow pools has a larger surface area, allowing the water to evaporate quicker leaving the salt behiend.
How do you separate flour and iron?
Pour into a sieve or colander, the sand will pass through the open mesh, leaving the larger marbles trapped inside the sieve.
What is honeycombing in cement?
Honeycombing - is pockets of air trapped during the mixing process. The air-pockets stay in the mixture while it hardens - leaving a weaker area where the honeycombing has occured.
