There are multiple methods of fossilization, but fossils generally are formed by rapid burial of organisms or traces of organisms by sediments.
Fossils occur when the organic material is filled with minerals or the cells of an organism is replaced by the minerals in water. Most of the minerals came from rocks and sands.
Here are the conditions for fossilization or permineralization:
1. Mineral-rich water like flood water or ground-erupted water.
2. Lack of oxygen - to prevent decomposition by oxygen.
3. Pressure - particularly in woods so that minerals can seep deep inside.
4. Usually occur within a few years - fossilization must occur quickly before decomposition takes place.
When a Plant or animal dies in a watery environment and is buried in sediment or soft tissues quickly decomposed leaving the hard bone or shells behind.
They are formed from the remains of animals or plants.
when fossile mould is filled it forms the model of the fossile
A coal-like residue, bulids up and forms around something to form a fossil. This fossil should be classified as a carbon-film fossil.
fossil
it hardens and molds the shape
Fossil fuels (coal, oil and natural gas).
The rock that forms is called a fossil.
Fossil records. Next time look in your textbook.
First, a thin layer of sediment hardens and forms a mold. Then, what is known as a cast is when a new layer of sediment fills in the mold breaking down the creature/ animal/fossil.
Fossil fuels are the forms of energy made from the remains of dead plants and small creatures. Examples of fossil fuels are coal and natural gas.
It was based on fossil evidence
There are four types of fossils that can be found. These are true fossils, mold fossils, trace fossils and cast fossils.
Coal, oil, natural gas, etc. are forms ofpetroleum and yes, petroleum in all forms, is a fossil fuel.
