Is graffiti public art? In my opinion graffiti is vandalism. From what I have read in the two articles some people see graffiti as art while others disagree. Graffiti destroys private property. Its cost a lot of the cities money to clean up the graffiti. Lastly the graffiti is being sold without the knowledge of the artist causing a stir. Graffiti is vandalism because it’s on private property. It’s not fair for the owners of the property to have their property destroyed. “I find it offensive to…

The most interesting part of the Flint River Aquarium was the planetarium. My first time in the planetarium is when I was very young so I really didn’t understand it. In the planetarium it’s like a movie theater, but instead of looking straight you look upward. They showed us the planets and tested our memory of the moon phases. After the planetarium movie was over we went to the Thronateeska. When we got to the Thronateeska, my group started with archelogy where we had to find ten buried items.…

Another place that I’ve been to recently and admired its geographical landscape is Mount St. Helens. The eruption on May 18, 1980 caused a monumental change in its geography, altering it to a point where it was unrecognizable. The current landscape is a combination of both aggradation and degradation caused by the rockslide debris that displaced the water of Spirit Lake, producing gigantic north part of the lake. When the water returned to the lake bed, it brought with it trees and soil in…

It is concluded that Yellowstone will someday erupt again however, it might not be in the near future. With the myriad of tourists that visit the National Park every year, they had to be sure that it wouldn’t explode soon to ensure people’s safety. Geologists have found that the ground around where the volcano is, is now swelling. The swelling indicates that the underlying magma chamber is refilling once again. But people have other questions, how was this volcano formed? Usually volcanoes…

1. Introduction 1.1 Literature Review “Land cover refers to the physical and biological cover over the surface of land, including water, vegetation, bare soil, and/or artificial structures” (Ellis, 2013).

Although, human have modified land for thousands of years for food, constructions or other things, the current rates, extents and intensities of land cover change are far greater than ever in…

NASA Discovered: We May be ‘Just A Cousin’ with Martian NASA (National Aeronautics & Space Administration) released the finding of the possible fossilized life on Mars. Three small rocks that NASA’s Mars Curiosity Rover examined on site identified to be the organic compounds that includes complex compound so-called PAHs. Nasa announced that this evidence may show the existence of primitive life in Mars. Ashwin Vasavada, project scientist for the Mars Science Lab (Curiosity), NASA Jet…

Wind Energy-The Power of the FUTURE How does wind energy work? When the sun warms the land on the Earth, the atmosphere heats also. Warm air rises and cool air sinks, therefore, when the warm air rises, the cool air from the sea replaces it. This movement of air is what makes the wind blow. When the wind blows against the wind turbines, this spins the blades. These blades capture some of the kinetic energy from the wind. The generator takes the kinetic energy from the spinning blades and turns…

similarities to Earth, the astronauts could test out new technology, and the most important thing, to learn techniques to live on other planets. Both Earth and Mars have many similarities. Scientists say that there may be a type of bacteria on Mars. If Mars has a bacteria that is a sign that there could’ve been life once. Earth and Mars would be very close in size if the Earth did not have national waters.The Length of a day on Mars is only about forty minutes longer than a day on…

There are many legends/stories surrounding the discovery of Saturn. According to mythology, the Assyrians were the first people to record sightings of Saturn. They spotted Saturn as a bright light and named it the Star of Ninib, in honor of the Assyrian sun god of springtime. Later the Greeks and Romans had their own ideas of this strange wandering planet. The Greeks named it Cronus, ruler of the Titans. The Romans later changed the planet’s name to Saturn. Both cultures identified Saturn as the…
