Successful fossilization or preservation of an organism can occur in several ways: (1) preservation without change; (2) complete replacement by a mineral; (3) filling in of a hollow space by a mineral; (4) formation of a thin film of carbon; and (5) formation of an imprint or the filling in of an imprint.
The four main ways a fossil can be destroyed once it has formed are physical weathering, chemical weathering, biological processes, and human activities. Physical weathering includes processes like erosion and abrasion that break down the fossil physically. Chemical weathering involves reactions with water, acids, or other substances that deteriorate the fossil's composition. Biological processes such as root growth or burrowing organisms can disrupt or destroy fossils, while human activities like excavation, handling, or development can also lead to their destruction.
Direct testing of the fossil material itself or materials associated with it, and indirect testing of material in stratigraphic contexts that bookend the fossil (i.e. a lava flow over the top of the layer a fossil is contained in).
They can cause diseases. Another way is that they can invade organisms.
Electricity does not inherently reduce the use of fossil fuels -- in fact, the production of electric energy is one of the biggest uses of fossil fuels. There are two ways that electric power can reduce the use of fossil fuels: Efficiency improvements, and alternate power sources. Efficiency improvements: * By replacing thousands of relatively inefficient fossil-fuel-burning engines with thousands of electric motors and a couple of highly efficient centralized fossil-fuel-burning electric power plants, the same amount of mechanical work requires less fossil fuel. * By using a microwave oven to cook food rather than a gas or electric conventional oven, only enough energy is used to heat the food itself, rather than heating up the internal structure of the oven and the air it contains, and maintaining that temperature for a longer time. Alternate power sources: Power can be produced in several ways that require no fossil fuels -- see the "What can you use instead of fossil fuels?" question below. Converting those forms of energy to electric power makes it easier to reduce or -- in principle -- eliminate the fossil fuel that otherwise would have been used to produce that electric power.

Organisms require energy to survive and metabolize nutrients. Organisms possess genetic material that codes for their characteristics. Organisms have the ability to reproduce and pass on traits to offspring. Organisms respond to their environment through behaviors and physiological mechanisms. Organisms have a complex organization at the cellular and molecular level.
Well, i do not know the most common three but i know that freezing, mummification and being preserved in tar can all happen Hope it helped Leila, 12
Huge deposits of carbon were stored over millions of years through processes like sedimentation and burial of organic matter, leading to the formation of coal, oil, and natural gas. These fossil fuels contain large amounts of carbon that were extracted from the atmosphere by plants and other organisms during their growth and then preserved underground.
Preserved remains are formed when the body of an organism is preserved and protected from decay through freezing, being trapped in tar, sap from a tree hardens around the body, or the body is put in a bog. (Like a peat bog.)
