What is one example of geologic evidence supporting uniformitarianism that Darwin observed in his travel?
Darwin found much evidence supporting the ideas of uniformitarianism. For example, he found fossil shells of marine organisms high up in the Andes mountains.
What was Darwin's role aboard the HMS Beagle?
He was the "naturalist" and "geologist". The Captain (FitzRoy) wanted the compaionship of a man of his class, and needed a geographer and oceanographer, and so took Darwin (as a self financing passenger - Darwin was not paid!) on board.
What is fossil rich limestone?
Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P
Do all organisms become fossils?
No. The hard bones are more likely to form a fossil. The soft parts will degenerate over time. This is why most of the fossils from the Pre-Cambrian and Cambrian periods are mostly shells, not the actual animals that inhabited them.
How many shells exists in an atom and what are the names of that shells?
The number of shells varies. The row number of the element is the number of shells. They don't really have names, but they're referred to by how many levels they are away from the nucleus.
What observations did Charles Darwin make about Galapagos tortoises?
turtles have shells....
What is the difference between sea shells and fossil shells?
Fossils are made of rock, which has replaced the original material.
Are Growth rings are found on both living and fossil clam shells?
No, growth rings are not typically found on living clam shells. They are commonly found on fossil clam shells and can provide information about the age and growth patterns of the clam when it was alive.
Can shells form a fossil?
Yes they can! In fact, shells are one of the easiest things to fossilize (the other is probably bone), and a majority of our knowledge on extinct, underwater invertebrates comes from their fossilized shells.

Why do you find shells in creeks?
The reason you find shells in creeks is beacause there once could have been an ocean there.
How did fossils become fossils?
It is the skeleton of an animal or shells pushed under rock for thousands of years and then it is a fossil.

What does most of the carbon in fossil fuels exist of?
carbon is an element, so "carbon" can't exist of anything. But the carbon found in fossil fuels are mostly from shells and dead animals or plants, after being exposed to imense heat and presure by stacking layers of sediment, plants and shells
What evidence indicates that the salt content of ancient oceans was about the same as it is today?
comparisons of modern seashells and fossil shells

What determines a fossil?
A fossil is simply any evidence of past life that is preserved in rock. That would include trails, footprints, burrows, poop, nests, bones, shells, and any other evidences.
