teaches that the first animals crawled out of the sea onto land and not reverse. How could this transformation of whales from land mammals to marine mammals happen? What group of land mammals gave rise to whales? Thanks to a profusion of intermediate fossils that were discovered within the past few years‚ these questions can be answered and the transformation of whales has become more clear. This paper will discuss the existing evidence‚ that whales descended from terrestrial mammals‚ from a palentological

Transitions and Organizational Patterns Part 1 Writers don’t let their thoughts wander aimlessly. They think logically. They organize details in patterns. In the written language these patterns help you follow ideas more easily and‚ therefore‚ improve your understanding of the text. Authors use transition words and phrases to create patterns within their writing. The following are common patterns of organization and transitions used in writing.

THE DEPLETION OF FOSSIL FUELS By Zoe Noonan Introduction As the world is becoming more advanced in technology‚ more energy is being used to keep up with the changing requirements. At the current rate at which energy is being used‚ the world will shortly come to an end of fossil fuels- the world’s primary energy resource. Abstract This research paper outlines the problems being faced by the shortage of fossil fuels‚ the effects they are having on the environment and the possible substitutes

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
