... 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 of early morning fog can form in valleys. At the Viking Lander 2 site, a thin layer of water frost covered the ground each winter. There is evidence that in the past a denser Martian atmosphere may have allowed water to flow on the planet. Physical features closely resembling shorelines, gorges, riverb ...

... and improve our global competitiveness. They cut America's demand for imported oil by nearly 100 million barrels a year—reducing our dependence on foreign oil suppliers and cutting our trade deficit. The future looks even better. Advanced-design nuclear power plants are now being developed—quicker and less costly to build, better performing, and even safer than today's plants. These plants will supply our children's and grandchildren's electricity—while helping to protect their environment. Cheers For Energy Efficiency We Americans should be proud of ourselves. Since the 1973 oil embargo, we've learned to use energy far more effic ...

... solutions involved making environmental changes on the international, industrial, and personal levels. Just how does acid rain form, and what consequences does it pose to our environment? There are numerous theories as to the cause of acid rain. However, the most prevalent is the theory that electric generating plants, heating plants, and other industrial plants have been emitting an excess amount of sulfur oxides, nitrogen oxides, and volatile organic chemicals (VOC’s) into the atmosphere. Once these chemicals are in the air, they react with water to form acids and fall back to the earth as precipitation. People who believe acid rain is a natural phenomenon do ...

... into three systems or categories . These different systems are sensory memory , short-term , and long-term memory. Sensory memory is the shortest and less extensive of the others. It can hold memory for only an instance (Memory p. 32). Suppose you see a tree , the image of the tree is briefly held by the sensory memory and quickly disappears unless you transfer it to your short-term memory (Rhodes p. 130). The next level is called short-term memory. The image or fact can be held as long as the brain is actively thinking about it (Loftus p. 392). For example , if you look up a number in the phone book and repeat it to yourself until you dial it , that is a form o ...

... in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of or ...

... would not cause a fire, but just below the cuts in the cable was a length of aluminum tubing, which took a ninety-degree turn. There were hundreds of these turns in the whole capsule. The aluminum tubing carried a glycol cooling fluid, which is not flammable, but when exposed to air it turns to flammable fumes. The capsule was filled with pure oxygen in an effort to allow the astronauts to work more efficiently. It also turns normally not so flammable items to highly flammable items. Raschel netting that was highly flammable in the pure oxygen environment was near the exposed section of the wires. At 6:31:04 p.m. the Raschel netting burst into an open f ...
