.... (7,923miles). It takes 23 hours and 56 minutes to rotate once, which is approximately one day. The sun orbits the sun ever 365.25 days. The average surface temperature is 15 degrees. The distance from the sun is 150million km (93 million miles). The sun is 150million km (93 million miles) away from earth. It is 1.4million km (864,000 miles) in diameter. Its surface temperature is 5,800 degrees Celsius (10,472 degrees Fahrenheit). As the earth rotates on its axis the sun can only shine at one side at a time. When the earth spins around one side receives the light of day and the other is .....

.... that we are willing to reap the rewards of our vast resources but we fail to see the harm that we are doing, and will continue to do if we do not stop these actions. Although his approach for explaining his beliefs changes, Suzuki's tone of great concern remains consistent throughout the essay. After his views are presented, Suzuki begins to tell us what we have done to our country and how we are destroying it. Present day Canadians are compared to native Canadians which successfully serves its purpose in illustrating how, for centuries, people lived off the natural resources in Canad .....

.... but I was just fascinated at the concept of cow poop being rolled into balls and taken away by bugs. To realize why dung beetles are so important, you must first know a few facts about them. Dung beetles are named after their delight in rolling up dung. Dung beetles utilize the dung of cows, horses, rabbits, deer, sheep, and many other animals. How many of you think dung beetles actually eat manure? The answer is yes. Dung beetles just love fresh dung. They shove the dung into their mouths, squeeze it, and drink the juices that come streaming out! The solid parts of the dung are squee .....

.... could get you to other stars as quickly and comfortably as envisioned in science fiction. Before this can become a reality, three scientific breakthroughs are needed: discovery of a means to exceed light speed, discovery of a means to propel a vehicle without propellant, and discovery of a means to power such devices. Why? - Because space is big, really, really, really big." (Why is Interstellar) For any human to ever reach another star, speeds greater than comprehension would be needed. Millis illustrates this idea on his web site, "The most obvious challenge to practical interstellar trave .....

.... and the customers. When commerce is conducted over the internet, a network is open to milions of potentially prying eyes. Moreover, there is no one to verify the validity of the credit card. To ensure that the person using the card is actually the card holder. The buyer might have exceeded the limit or can be using a stolen card. Likewise, the buyer has no assurance that the vendor on the other end is who he/she claim to be. Richard E. Smith in Internet cryptography says that data travels from one computer to another leaving the safety of its protected surroundings. Once the data is out o .....

.... that gets worse with time. It used to be assumed that this change was a normal part of aging that we called senility. Some people develop this condition when they are as young as 40 years of age. However, the disease is most common in persons over the age of 65. It is estimated that approximately 10 percent of persons over 65 years of age may have Alzheimer’s disease and that in persons over the age of 85, up to 50 percent may be affected. Alzheimer’s disease is not a normal part of the aging process. It is not contagious, and it is not known how it can be prevented. While the .....

Environmental policy is based upon the concern for natural resources, human health, economic growth, energy, transportation, agriculture, industry, and international trade. All parts of the society are involved. The EPA is responsible in making our communities and ecosystems diverse, sustainable and economically productive. Overall, the United States plays a leadership role locally and globally. With its policies, the EP .....

.... being used today. Hot water, at temperatures between 300 and 700 degrees Fahrenheit, is brought from an underground reservoir to the surface and is converted to steam by using changes in pressure. The steam and liquid are separated, with the steam turning turbines (generating electricity) and the water is injected back into the reservoir to maintain the chamber's pressure. Sometimes the hot water is used directly for home, and sometimes greenhouse, heating. It is also used to speed up the growth of aquatic animals (aquaculture). II. Dependency on Geothermal Energy Although we (the U .....

.... the reason for this is believed to be caused by a few things. Deforestation, fertilizer use and fuel combustion are minor contributors to this problem while chemicals such as chloroflourocarbons (CFCs), halons, carbon tetrachloride, methyl chloroform, methyl bromide and hydrochloroflourocarbons (HCFCs) are the major contributors to the deterioration of the ozone layer. These chemicals have industrial halocarbons that break up into chlorine and bromine in the upper stratosphere when they react with the sun's rays. Chlorine eats up the ozone layer while bromine acts as a catalyst and speed .....
