Fossils

Erosion

What are other types of evidence for evolutionary theory, other than fossils?

Darwin's observations on the voyage of the Beagle, and succeeding scientist's observations that conform to his hypotheses. Domestication of plants and animals by purposeful and accidental selection over the past ten thousand years. Real-time observation of changes in bacteria, viruses and simple animals. A hundred years of fruit-fly experiments. DNA analysis and genetic decoding. The appearance of new stains of drug-resistant microbes comes quickly to mind. The breeding of animals for hunting and agricultural purposes, and for sporting purposes and pets, has been practiced for 1000s of years and is essentially human-directed evolution, and in many cases is historically documented. The principals of getting a good goat or cow were known and practiced long before anybody thought to extrapolate them backwards to the origin of a species and call it a scientific theory.

In most cases both the limestone AND the fossil will be dissolved by the vinegar (eg a crinoid in Carboniferous limestone), so no. However, some fossils (eg echinoderms in the Chalk) are silicified and in these cases dissolving the limestone in vinegar will expose the fossil in spectacular detail and in other cases the fossil will dissolve more slowly than the matrix, so yes. .

In other words there is NO true or false answer, fossil preparation and conservation is a discipline in itself.

Fossils indicate several things about Earth's past:

- the organisms that lived then, and by extension the organisms in their food chain

- the climate in the area where the organism lived

- how plate tectonics have moved landmasses that once were joined together

I am pretty sure grainy rocks because they are more common than crystals. They are more likely to contain sea creature fossils. They are likely to have sea creature fossils in them because the land we stand on now, was once covered in water.

by carbon dating it is testing how much radioactivity is in carbon 14 because radio activity has a half life so how much radio activity is left then they can determine how old it is

Fossils are used by scientists to answer questions about species and maybe even dinosaurs. They use the fossils and run tests by using there DNA and seeing their molecular structure and running it by other animals for similarity's.

Wind energy is not better than water energy. They are both very similar in that they are:

* free (after the initial cost of the turbines)

* sustainable (they won't run out)

* renewable (they are still there tomorrow even if we use them completely today) If there is no wind, then the wind turbines don't turn to provide electricity. This can happen quite often, unless the turbines are placed where the wind blows non-stop all year round.

If there is no water, then the water turbines don't turn. This will happen only rarely if the turbines are placed in the best position. Using ocean waves and tides will be more reliable than rivers which can dry up in droughts.

Most dead organisms are eaten or rot away quickly. If a fossil is to form, the body has to fall somewhere it is protected physically and chemically. It then has to be in a position where rocks form around it, and it has to remain fairly intact whilst its shape becomes preserved in stone. There are a lot of odds against the process.

There may have been a heavy snow fall which caused the remains of dead plants and animals to be encased in ice.

it can be sedimentary rocks

According to the geologic Law of Superposition, in undisturbed rock strata, the deepest rock layers are always the oldest. Accordingly, a fossil found in a lower layer of undisturbed rock would be the older.

The fossil record provides scientists with a time lapsed view of plant and animal life. Scientists are then able to use carbon dating and scientific inquiry to determine when each type of plant and animal species lived.

When dinosaurs die their bodies decay and leave bones. The bones become buried over time under layers of sediment. When enough heat and pressure are generated, the sediments undergo metamorphism. The bones are crushed and turned into a liquid due to the extreme heat. This liquid is boiled and finally turned into natural gas, which is located sometimes miles underground. Hope that helps

Fossils form through the process of mineral replacement beginning when an organism dies and is buried. Groundwater seeps around the organism, and the minerals in the water gradually replace the minerals in the hard parts of the organism. Over time these minerals turn into a stone replica of an organism.

the answer is elemetary

Sometimes they do! But this is very rare!

When an animal dies, other animals will quickly eat any soft tissues exposed. If this does not happen, bacteria will rapidly decompose the soft tissues.

To get the soft tissue preserved needs very specific conditions which are quite complex. It would be worth reading about Mazon Creek and Burgess Shale, these are places where fossils with soft tissues preserved can be found.

Index fossils work similar to counting populations of living creatures. An increase or decrease in populations of certain creatures can provide clues to the climate and climate changes.

The Himalayan Mountains were gradually "pushed up" by plate tectonic shifts over several eons, but their peaks had at one time been below sea level - and covered by a shallow sea. That is where the fossils came from.

No, it doesn't. consider for a moment that about 98% of all life on the planet is extinct. Now consider that the conditions necessary to produce fossils does not exist everywhere. You have a clue to why we do not have a complete, or even a miniscule record of the history of life on Earth.

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
