paleontologist‚ now you can. Fossils are the oldest rocks on earth. They can be anything that was over 4‚000 years ago. Fossils are what tell us what come before humans a million years ago. Do you ever stop and think there might be a T. Rex under your house. Well fossils preserved remains of organisms. Fossils can be over 4‚000 or a million years old. Usual the preserves are of animals. Fossils arranged from the size of a mouse to a ten story building. This is how all those fossils are made. The dead animal

12.1 The Fossil Record 1. Form in Several Ways (The following are some of the processes that make fossils.) a. Permineralization minerals carried by water are deposited around a hard structure (may replace the hard structure) The most common fossils result from this process. A1. Natural Casts form by water removing the bone/tissue‚ leaving an impression in sediment. Minerals fill in the mold‚ recreating the original shape of the organism A2. Trace fossils record activity of an organism. Ex

6 Ocober 2013 Fossil Fuels and Alternate Energy Sources In the early 1900s‚ fossil fuels were the primary source of energy‚ but in more recent times with reserves diminishing and global warming becoming a major issue‚ we are forced to develop alternate sources of energy. According to Melosi‚ Governments became aware of the effects of fossil fuels as early as the 1950s‚ and in an attempt to combat this‚ they passed laws to try and lower the amount of pollution it caused (The Automobile and

Fossil Fuels: Rape of Nature {Student name here} {Class name here} {Professor Name here} {Due Date} Fossil Fuels‚ which include coal‚ oil‚ and natural gas‚ are a non-renewable energy source that were formed from the decomposition of plants and animals that were deposited in the Earth around 300 million years ago. These fossil fuels‚ after being removed from the Earth‚ are converted into energy and this energy is essential to modern society (Chughtai & Shannon‚ 1998). Over 85 percent

The Fossil Fuels Introduction Fossil Fuels are a non-renewable energy source. They are found in Earth’s depositions made over millions and millions years ago and are called non-renewable because they can’t be used again once they are spent. There are three major forms of fossil fuels: coal‚ oil and natural gas. COAL Coal is made up of carbon‚ oxygen‚ hydrogen‚ nitrogen and some amounts of sulphur -Three main types of coal: • Anthracite : the hardest and has the most carbon in

Energy in the form of fossil fuels‚ can it meet all of society’s needs or is it time for us to look at other alternatives before it is too late? The increasing pollution and price of energy has once again ignited the debate about options for future energy. Fossil fuels are hydrocarbon deposits also known as coal‚ crude oil and gas derived from the remains of organic prehistoric plants and animals. They have taken many millions of years to form. Coal is ground to a fine dust when crushed and

While fossil fuels are critical for the operation of our world their inefficiency and environmentally damaging characteristics take away from their appeal. Currently there are no suitable alternatives to our natural resources because they supply such a large amount of energy to so many people. Because of this research is being conducted to make our resources more efficient‚ and to find alternatives. This essay addresses the environmental impacts of our fossil fuels.

Palsch 1 Don Palsch Professor Sundvall ENC1101 28 of September 2013 Alternative Energy vs. Fossil Fuels There are many alternatives that can effectively replace fossil fuels. Even though the United States is still dependent on fossil fuels; we have been working vigorously toward alternative energy. In the future the goal is to be completely independent from fossil fuels. Alternative energy has many different kinds of sources such as biofuels‚ hydrogen‚ solar‚ geothermal‚ and nuclear

What fossils tell us This chapter looks at fossils and their formation. Fossils are traces of ancient plants or animals preserved in rocks. The number of fossils and their placement in rocks is called the fossil record. The study of fossils is called palaeontology. Because fossils are buried in rock‚ most of the time they are found only when the rock is dug up‚ worn out or cut away. Fossils may include parts of animals‚ their footprints‚ eggs or nests. Plants and their spores‚ or seeds‚ also make

Fossil fuels Oil 1) Oil is produced in Middle Eastern countries‚ Saudia Arabia accounting for 13.1 per cent of the world total‚ America 16.5 per cent and Africa 12.1 per cent. Although the Middle East has a lot of oil reserves not much is consumed. North America‚ Europe and Eurasia consume a lot of oil. This is due to the countries being MEDCs so they will need more fuel as the demand is higher. 2) The factors which cause oil prices to increase are from supply shocks (the OPEC oil embargo
