selecting mates. Anthropogenic sounds have negative effects on marine life. Humans produce their own underwater sounds through activities such as aircraft over flights, boats and ships (vessels), tourism, stationary offshore activities, air gun firing, sonars, explosions, and methods to control movement of marine life (W. Johnson Richardson and Bernd Würsig, 1997). Many studies have discovered vessels to be the main contributor

As time slowly passes us by human beings continue to find more and more innovative ways to make their lives, and those of people around them, more efficient and enjoyable. People will always strive to make daily activities less costly, dangerous, and stressful by adapting new revolutionary technologies as they readily become available to them. Ever since the invention of the first true gasoline automobile powered by an internal combustion engine in 1885/1886 (“Who Invented the Automobile?”, par.

First, Marie Curie should be considered as a modern day hero because she exhibits leadership for women. One example is Curie graduated first in her class, even though she was a women. A book indicates, “On June 12, 1883, Manya received the gold medal awarded to the top student in her high school graduating class” (Cobb 18). Marie was excellent in school, even though she was in the minority. At age fifteen she graduated as the top of her class. With this she earned the gold metal to show how much

In the midst at the lake in Scotland, appeared a monster. They called her the Loch Ness Monster (Nessie). The mystery of the Loch Ness Monster, although supposedly seen by people, is still unproven. The legend of Nessie started in the year 1933. Facts about the monster is the surgeon's photo was a hoax. The legend of the Loch Ness monster all started on May 2, 1933. When the story of the monster first appeared in the paper. The first photo evidence of the monster was also taken in the year of 1933

Oil is a very important fossil fuel that is used for various sources of energy. Oil supplies power to industries, fuel for transportation, heat for buildings, and provides raw material for plastics, paints, textiles, and other materials (hybrid cars). To access this fossil fuel, oil drilling is used. Land-based oil drilling became less productive and as the global stipulation for energy increased, technology, law, and geology impacts stepped in and pushed the exploration of oil away from shores (CITE)

excavation methods. Due to the influx of new technologies and innovations in recent decades, archaeologists have been able to excavate previously inaccessible areas. For example, new diving equipment and tools such as proton magnetometers, side-scan sonar, sub-bottom profiler, and miniature submarines have allowed archaeologists to dive into the deep depths of the ocean. As a result, the branch of underwater archaeology was created to search for shipwrecks and other artifacts on the ocean floor. Underwater

Good evening and thanks for tuning in to the ABC, I am your host for this evening Josh Jacquet, and on today’s show we will be continuing our series on the topic of the Cold war but today we will be exploring the Vietnam War into detail. The topic that will be discussed tonight is that towards the end of the twentieth century the amount of democratic countries had quintupled. This was not expected at the beginning of the twentieth century. Now the question is Did the US use the cold war to further

Before World War 1 the last war fought was the Franco-Prussian war which concluded in 1871. During that war mainly cavalry was used and the battles were for the most part brief. European nations went into WW1 with the notion that it will be just like the Franco- Prussian war and battles would be just as short;, they had forgotten the toils of war. The First World War proved dramatically different, it saw 20th century military technology on 19th century tactics. Soon it became a war of attrition,

Abstract The research question that I chose to investigate was: Is it possible for mermaids to exist? I chose to do this because there seems to have been a lot of different controversies on the topic before the semester started. I am supporting the claim that it is possible for mermaids to exist. The main reasons for supporting the claim, is because there are similarities in humans and aquatic mammals, there is a gap in the evolutionary fossil record, and there are mysterious findings and recordings

When someone says “superhero,” it is automatically assumed that one is talking about someone who saves others using extraordinary powers or someone who is there to protect and make others feel safe. For decades, superheroes have been around fighting crime and saving civilians from the villains that reign. These superheroes create a light and give the viewer some kind of hope. Although a superhero is seen as someone who is god-like, there is one hero who defies this stereotype. His name: Batman. Batman
