Among the possible environments that might hold fossils:
You cannot say for certain that there were no land creatures, but because land fossils would be exposed to erosion and weathering. Most fossils are formed as a result of a tranquil marine environment allowing the dead organism to sink to the bottom of the water body, and are covered. In the absence of oxygen, the form is preserved and is fossilised.

A2. The soft parts of an animal are least likely to survive, for these will be degraded by bacterial and insect action, if not by larger scavengers. If an animal dies on the land surface the chances of fossilization are minute.Good preservation of a fossil depends greatly on the environment in which the animal dies. If it is a very fine-grained silt, the probability of preservation is good, particularly of fine detail. The environment is likely to be anaerobic, and even the body's internal bacterial flora may be unable to survive in an anoxic environment.One of the remarkable preservations was the Archaeopteryx fossil, on which even the feather detail may be seen. Discovered quite soon after Darwin had launched his Origin of Species.Unusual preservation localities include swamps, and the remarkable La Brea tar pits. Another unusual fossil preserve is that of insects and spiders preserved in amber originally a gum exudate from trees.
Nobel gasses.
Yes they are, or al least most likely they are.
There are at least 600 coal fired power plants in the US, providing 31.2% of U.S. electric capacity (as of 2005).
An evolutionary biologist is least likely to collect data by doing controlled experiments. Evolutionary biologists study living organisms through the lens of evolutionary theory.

The least body part of a dinosaur to be likely as a fossil are the muscles.

Of the three organisms it is the snails that has the least chance of becoming a fossil since it has no skeleton.
What a good question. I suppose it is likely to be a baby animal. A Chick maybe.

A number of dinosaurs, such as Amphicoelias are known from only one fossil specimen. Many other dinosaurs were never preserved as fossils and so will never be known to mankind.
Yes, because they usually rot away with the skin and other flesh and organ things.
