... The helium is actually solar wind that is trapped by Mercury’s weak gravity. Scientists think that collisions with protoplanets early in the history of the solar system may have stripped away lighter materials, making Mercury a very dense planet with an iron core extending outwards 4/5 of the way to the surface. Mercury bares a very similar resemblance to our moon because it has a lot of craters. The craters, which cover seventy-five percent of Mercury’s surface, were formed by huge rocks that smashed into the planet’s surface. The largest crater is called the Caloris Basin and it is 1400 km in diameter and is flooded with molten lava. Mercury also has many cli ...

... monitored in their jobs" (462). As computer systems become more sophisticated this number will drastically increase. As we enter this new age of technology we must remember that with more power comes more responsibility by employers and employees alike. Micheal J. Smith, a professor at the University of Wisconsin-Madison explains that knowledge can be used as a weapon or as a tool (DeTienne 462). For instance monitoring abuse can be found in the in the situation of airline agents. The agents discovered that by keeping customers on hold while finishing their work they could gain an extra 5-minute break (De Tienne 462). In the future these evasions of work will be ...

... them, the author would not have been able to supply sufficient proof to his findings and convince the reader of the true severity of acid rain. Collins used noteworthy facts throughout the essay to prove is point about how severe acid rain truly is. The facts that he used added substance to the essay by validating his point of view. In the same way, the author used effective illustrations and examples to prove his point. These examples and illustrations simplified the readers understanding as to how severe acid rain is and how we can try to prevent it. For instance, one great illustration adopted in the essay reports, “Lumsden Lake, on the north shore of Ontari ...

... and their ecological symbionts in a process known as coral bleaching. As mentioned earlier, coral reefs are among the most diverse and productive of all communities on Earth. They are also the largest biological structures on the planet. The Great Barrier Reef, along the eastern coast of Australia, covers over 2000 kilometers and is said to be visible from the moon (Goreau, 1987). While the size of coral reefs can be enormous, their real impact is on a much smaller scale. Reefs function as food and shelter for fish and marine invertebrates. While the coral itself is an animal, through a symbiotic relationship with the unicellular algae, coral becomes the pr ...

... chlorine. In some cases, these nutrients are found to be missing in soils, but it is extremely uncommon. As plants need to retrieve all of their nutrients from the soil, many methods have been developed in order to find ways to improve or change the soil to suit the plant's needs. Soil, in science as well as in common gardening, must undergo detailed inspection, to detect such things as the pH of the soil. A soil with a pH above 7.0 is called an alkaline soil, and will commonly kill plants. Mineral content, as mentioned above, is also a concern, and must be clearly monitored. After inspection, it is common for minor organic materials outside fertilizers to be ...

... in supplying the demand and now that same synthetic compound is used today. My theory is that the same thing will happen with such things as plastic, which is made from fossil fuels. Someone will either come up with a synthetic plastic or come up with something to substitute for plastic. The person who comes up with the solution will become and instant millionaire and everyone will be happy. There is one draw back of this way of solving problems, I mean sure it's great to wait until the demand but we should still learn from our mistakes. We should learn to plan ahead and see what the consequences could possibly be. We still have other demands to meet, t ...

... on one's knees with corrugated streaks of purplish flesh. Little did I realize what it takes to recover. My father had orthoscopic surgery twice, and both times he was walking within a day and cycling within a week. I assumed my recovery time would be similar to his. Never in my life have I been so wrong. Due to the nature of the injury, the doctor elected to stitch my cartilage back together. Because of the intricacy of the operation, I was restricted to non-weight bearing activities for three weeks. If I wished to return to wrestling, the doctor stated that I would have to demonstrate a muscle strength in my injured knee equal to ninety percent of ...

... beautiful trees' it's wonderful sights and killed nearly one hundred people, and covered a small town near Alberta with ice and snow. Another devastating avalanche incident is the 1964 Sherman slide, in which a huge avalanche was triggered by the 1964 Alaskan earthquake. The slide spilled out onto the Sherman glacier, during the big slide several other smaller slides happened and those were the one that took lives in Anchorage, and destroyed property There are a couple of types of avalanches and how the destroy so much this one is named "Loose Snow Avalanches"1, it starts' in a small area then grows in size and mass as it descends.Another type is the "Slab Avalan ...

... it to a known mass period. The relationship m1=m2T12/T22 was discovered. Objective: After completing the experiment, we will be able to find the mass of objects using an inertial balance and compare them to accepted measures. Materials: C-clamps, inertial scale, a watch with a second hand, and a triple beam balance. Procedure: 1) The class will measure the period of oscillation of their balance pans when they are empty. The accepted period will be the average of the class. To find the period, you will measure the amount of time it takes for your balance to complete 20 oscillations. The period (T) will be computed by taking your time and dividing it ...

... concept of a black hole came about, and give some insight on how black holes are formed and might be tracked down in our more technologically advanced future. Gaining an understanding of a black hole allows for a greater understanding of the concept of spacetime and maybe give us a grasp of both science fiction and science fact. Hopefully, all the clarification will come by the close of this essay. A black hole is probably one of the most misunderstood ideas among people outside of the astronomical and physical communities. Before an understanding of how it is formed can take place, a bit of an introduction to stars is necessary. This will shed light (no pun int ...
