Fossils

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

Less than 1% of all organisms that die become fossilized.

The burning of fossil fuels is bad because it causes carbon dioxide levels to rise in the atmosphere. This extra carbon dioxide adds to the enhanced greenhouse effect causing global warming. This is why burning fossil fuels is bad.

If we use more fuels then we should, the planet and mankind itself suffers in the long term. Pollution is a natural and problematic affect of this overuse.

It causes pollution.

Fossil fuels are bad for the environment because they create greenhouse gases which go up in to the atmosphere and magnify the suns heat which can cause ice caps to melt then that leads to the sea level rising which causes flooding and if too much ice melts animals in the Arctic could die.

By using relative age. Over a long period of time, sediment will, layer by layer, coat and cover the fossil, making it difficult for paleontologists and scientists to figure out how old the fossil really is.

Often, but not always!

The definition of a fossil is a whole, part or impression of an organism from a past geologic age, embedded in natural materials, such as rock, sediment, resin, petrified bones, or wood.

One condition that best increases the chance that an organism will become fossilized is if the burial happens rapidly. Another condition that can increase the chance of an organism becoming fossilized is if the organism has hard body parts.

This is because of the way that it is formed.

When you have a rock that is formed through metamorphisis then it has been created through heat and pressure acting on other rocks.

Fossils are inherently delicate things and therefore precious little would withstand the conditions that are required to create marble - and therefore marble hardly ever contains fossils as a direct result of this

The most usually fossilized parts of organisms are bones and shells. These are least likely to rot or wear away before they are buried and mineralised. In rare instances the soft parts of the bodies are preserved and are normally shown as thin films on the rock surface.
