.... what we know now is not even close to everything about the planet. As time goes on, our knowledge of this mysterious planet will expand. The atmosphere of Mars is quite different from that of Earth. It is composed primarily of carbon dioxide with small amounts of other gases. The six most common components of the atmosphere are Carbon Dioxide at 95.32%; Nitrogen at 2.7%; Argon at 1.6%; Oxygen at 0.13%; Water at 0.03%; and Neon at 0.00025 %. Martian air contains only about 1/1,000 as much water as our air, but even this small amount can condense out, forming clouds that rise high in the atmosphere or swirl around the slopes of towering volcanoes. Local patches .....

.... have ever thought over the question of why people use drugs, you would realize that the question is not as simple as it may appear. To answer this question objectively, you need to consider how the body and mind work together. The simple act of daily living creates countless demands on ourselves both emotionally and physically.

The body, in most instances, craves a minute amount of the chemical to balance its desires; however, the mind says, "If a little is good, a l .....

.... ozone layer protects the Earth and its inhabitants by screening out this harmful light. For " millions of years ozone has been protecting the earth " by absorbing ultraviolet or bad radiation from the sun ( Rowland, 1992, p.66 ). This natural umbrella protecting mankind has recently suffered the effects of industrialized society. This " ozone shield is dissipating " and the cause is laid primarily to man - made chemicals ( Bowermaster et al, 1990, p.27 ). If enough of these man - made chemicals are released, " the ozone layer would be weakened to such an extent that it does not filter out the sun's invisible and dangerous ultraviolet rays " ( Jones, 1992, p.3 .....

.... of facts, they promote their hidden agendas in the halls of the United States congress. Genetic engineering is a safe and powerful tool that will yield unprecedented results, specifically in the field of medicine. It will usher in a world where gene defects, bacterial disease, and even aging are a thing of the past. By understanding genetic engineering and its history, discovering its possibilities, and answering the moral and safety questions it brings forth, the blanket of fear covering this remarkable technical miracle can be lifted. The first step to understanding genetic engineering, and embracing its possibilities for society, i .....

.... Australia they are called Willy-Willys. In the Indian Ocean they are called Cyclones. The North Pacific has the greatest number of these storms, averaging 20 per year. Fortunately for those living in the coastal regions of the southern and eastern United States, fewer than five hurricanes, on the average, develop each year in the warm sector of the North Atlantic. Although hurricanes are most noted for their destruction, some parts of the world, especially eastern Asia, rely on them for much of their precipitation. Although numerous tropical storms develop each year, only a few reach hurricane status, which by international agreement requires wind speeds .....

.... element design. The flow control element is the part of the valve that controls the flow of fluid through the device. Most take their name from the type or des8igh of the flow control element. The body of the valve contains useful information referred to as bridge wall markings. This is specific information about the valve. One of the more common found in industry is a gate valve. A gate valve is typically operated in the wide-open, or completely shut position. This type of valve is used where flow rates are not restricted. Globe valves are the second most common valve used I industry. A globe valve places a movable metal disc in the pa .....

.... one is taking it for granted. Another form of is chemical pollution. There are approximately 2 trillion travel industries in this world and they all contribute to the chemical pollution, weather it is cruise ships, hotels near the water, or boat tours. Fishermen also pose a threat to our oceans by over fishing our waters. The way they are going there will not be enough fish for a maximum sustainable yield, and our fish population will die. Fishermen also clean there fish and throw the guts overboard into the ocean. Industrial, agricultural, household cleaning, gardening, and automotive products are also polluting our ocean. You wouldn't believe it but all of .....
