An index fossil is formed from the remains of an animal that evolved and lived for a precisely defined (and hopefully short) period of time, they are used to define and identify geologic periods. The best index fossils are wide spread (globally) and numerous (commonly found). They frequently (but not always) bottom dwelling or burrowing organisms with hard parts to their body structure because such organisms are most likely to regularly leave remains that can be fossilized.

What is a true fossil?
A True form fossil is a fossil of the whole/entire body of the organism.
If a leaf is fossilized it would most likely form what type of fossil?
Probably, carbonateous fossil.
Are fossil fuels carbon-based?
Burning fossil fuels releases carbon into the atmosphere in the form of CO2. Yes.
What is 420 in index form?
It is: 4.2*10^2 when in scientific notation
Do fossil form in shale or halite?
Fossils could form in shale. Halite is table salt, a mineral with a crystalline structure that is not compatible with understood fossil formation methods.
Are certain conditions necessary for fossil to form?
yes not all the conditions but some.
What conditions are necessary for a fossil to form?
Hard parts/quick burial
What conditions are needed for fossil to form?
When an animal or plant dies, usually the remains are eaten or decompose. On occasion though, they get buried by mud or sediment, and in the right conditions, they harden into fossils.The bones or original material decay, and water or other things seep into the impression left by the original material. This water and minerals continue to dissolve the original material, replacing it, and then they harden over time.So, right condition, pressure of the mud on top it is most needed to form a fossil
What is fossil form a specific time period?
Index fossils (also known as guide fossils, indicator fossils or zone fossils).
What is the singular form of index?
"index" is the singular form - "indices" is the plural :)
Are certain conditions necessary for fossil fuel to form?
yes not all the conditions but some.
How can imprints form a fossil?
It takes several millions of years for a fossil to be created. First an animal may step in mud whichs dries over time and becomes hard. After it has that mold the conditions have to be right for it to form. If they are then it will form.
What is 70 as a product of prime numbers in index form?
It is: 2*5*7 = 70 and no indices are needed
What is the possessive of index?
The possessive form of the singular noun index is index's.
What conditions led to form trade sociteties?
The working conditions in the places that the workers worked at...they needed to be more sanitary.
What are the three components that are needed to form fossil fuels?
Fossil fuels are formed from the remains of dead plants and animals, which undergo decomposition under high pressure, heat, and anaerobic conditions over millions of years. These three components - organic matter, heat, and pressure - are essential in the formation of fossil fuels such as coal, oil, and natural gas.
What weather conditions are needed for snowstorms to form?
More than just two conditions are needed, but the two most important ones are convective instability and wind shear.
