GEOLOGY

Detailed explanation-1: -Answer and Explanation: The preservation of remains of organisms usually occurs in nature as a result of either ice, amber, or tar.

Detailed explanation-2: -The low temperatures of frozen soil and ice can protect and preserve organisms. Because most bacteria cannot survive freezing temperatures, organisms that are buried in frozen soil or ice do not decay.

Detailed explanation-3: -Tar is also a good natural preserver of animal and plant remains. After specimens were sucked into these sticky asphalt pits, the tar would do a great job of starving them of oxygen and protecting them from the elements, allowing the animal’s “hard parts” (bones and teeth) to remain intact.

Detailed explanation-4: -Hard parts of plants and animals, such as skeletons and shells, are most likely to be preserved as fossils.
