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.
How does sediment size affect fossil formation?
Sediment size can impact fossil formation by influencing the preservation of delicate features. Fine sediments can help to preserve fine details of fossils, while coarse sediments may damage or wear away delicate structures. The size of sediment can also affect the rate of burial and exposure of fossils to oxygen, which can impact decay and fossilization processes.
What is the typical condition necessary for fossil formation?
Fossil formation typically requires the rapid burial of an organism in sediment, which helps protect it from decomposition and scavenging. The organism's remains undergo a process of mineralization over time, where minerals replace the original organic material, preserving the structure of the organism as a fossil.
What conditions are worst for fossil formation?
The worst conditions for fossil formation include environments with high oxygen levels, which promote decomposition and prevent organic material preservation. Additionally, areas with rapid sedimentation can bury remains quickly, but if conditions are too extreme, such as high heat or pressure, it can lead to destruction rather than fossilization. Lastly, environments that lack suitable minerals or have acidic conditions can hinder the mineralization process necessary for fossil development.
What is the best type of rock for fossil formation?
Sedimentary rocks (such as shale, sandstone, and limestone) are the best types of rock for fossil formation. These rocks are formed from layers of sediment that can preserve and protect fossils over time. Additionally, the fine-grained nature of sedimentary rocks allows for the detailed preservation of fossils.
What characteristics make these enviorment a well suited for fossil formation?
A well-suited environment for fossil formation includes sedimentation conditions that rapidly bury remains to protect them from decay and scavengers, as well as an absence of oxygen to slow decomposition. Additionally, environments with low acidity levels help preserve the organic material, contributing to fossil formation.
Why do we only have fossils of a fraction of things that have existed on earth?
Many environments are not suitable for fossil formation.

Which is leading theory for for formation of fossil fuel?
orgenic matter was compressed and heatedBy: crystal :)
Which is not a factor in the formation of a fossil fuels?
Temperature and pressure are not factors in the formation of fossil fuels. Fossil fuels are formed from organic matter, such as ancient plants and animals, that is buried under layers of sediment and undergoes chemical changes over millions of years to become coal, oil, or natural gas.
What characteristics make areas along hillsides and layers of sedimentary rock well suited for fossil formation?
no exposure

The organism's remains undergo a process of mineralization over time, where minerals replace the original organic material, preserving the structure of the organism as a fossil.
Are fossil fuels produced today by the same geologic processes as in the past?
Yes.
Which conditions are worst for fossil formation?
Conditions that are worst for fossil formation include acidic environments that can dissolve bones, high temperatures that can accelerate decomposition, and high-energy environments like flowing water that can break apart bones before they can fossilize. Additionally, conditions with high levels of oxygen can increase decomposition rates and reduce the chances of fossilization.
What can a fossil be preserved in?
Sediment and tree sap
