Possible Impacts of NEOs with Earth Research Paper

Possible Impacts of NEOs with Earth - Research Paper Example When deciding the potential danger an NEO can ensue, the Torino Impact Hazard Scale, or simply the Torino scale, is consulted, which measures and categorizes the impact hazards that are associated with near-Earth objects. The Torino scale ranges from zero to ten, with zero is that there is no likelihood of a collision, though it also applies to smaller objects that burn up within the Earth’s atmosphere, and ten meaning that a collision is most certainly going to happen, â€Å"threatening the future of civilization as we know it.†3 The Torino scale is also split up into five colored zones: white, meaning no hazard, which consists of the zero level; green, normal, which consists of level one; yellow, meriting attention by astronomers, which consists of levels two, three and four; orange, threatening, consisting of levels five, six and seven; and red, certain collisions, which consists of levels eight through ten. Each color and number reveals certain levels of danger and damage in regard to each NEO that is discovered. The Torino scale allows astronomers to understand and keep an eye on certain NEOs that they believe could collide with the Earth, as well as brushing aside the ones that stand no chance of a collision. A meteorite hitting Earth’s atmosphere is a very common occurrence, though these are usually small enough to burn up within the atmosphere. Many of them that do make it past the atmosphere is tiny, often pebble-sized, by the time that they land on Earth’s surface. There are thousands that do not even make it to pebble-sized but end up as bits of dust. This in itself shows that an NEO impacting the Earth is very plausible, as it happens often with smaller, almost unnoticeable objects. It has been estimated that approximately 37,000-78,000 tons of mass of material fall to Earth on a yearly basis.4  There is sufficient proof that larger NEOs have collided with the Earth in past centuries, such as the asteroid that presumedl y wiped out the dinosaurs millions of years ago. Another larger NEO that has collided with the Earth is the meteorite that formed Meteorite Crater in Arizona over 50,000 years ago.

Psych research paper - Essay Example If we would listen to our physical and inner emotional needs more maybe we would not always be sick with the problems associated with stress. I say this only because I have had my share of anxiety and stress, and know that it can take a toll on a person if not taken care of properly. Lisa is a friend of mine that I have not seen since she became a L.P.N. this past summer. We started to catch up on life and even some gossip. This is when I noticed something was not quite right with her. We talked a little more and I still had a feeling she was not telling me something. Later in the week I spoke to a mutual friend and asked her if she had spoken to Lisa. It was then that I found out she had been having anger issues. Our friend told me of a couple of different incidences that Lisa was involved with. Both times she got very anger, very quickly at things that should not have mattered. The friend also told me she was drinking a little more often and when out she was either quiet or very loud to the point of being obnoxious. This was not the person that I knew at all. This was a person who always seemed to have things together. I had asked if anything was going on that I did not know about that would make her this way. The friend told me about her switching positions a t the hospital because of her being a nurse now, and said she was not handling the stress of that very well. That was all she told me about. Again I knew that this still was not her to be like this over something like a new job that I knew she was anxiously waiting to do. Later in the week I called Lisa to see if see was home. When I spoke with her again I could tell she still was not herself. I came out and asked if there was something wrong with her and she then started to cry on the phone. She then told me how the new job was not all what she thought it was going to be. It turns out to be a very stressful job with lots of patients to care for and very
