Comet Research Paper

The Yellowstone volcano is very active volcanic system which requires much observation. The geysers, mudd pots, hotsprings and steam vents are all examples of the heat from molten rock of a volcano. For many years the Yellowstone volcano could not be located. There is not obvious signs of a volcano, but scientists looked for other clues. Rhyolite is present in a location that has pinetress and many mosquitoes can be found due to the lakes that have formed. Rhyolite is a very violent eruption, due to the high silica content,  it flows slowly, like honey, and tends to pile up and form lava

The estimated age of the earliest above ground (subaerial) eruptions of Kilauea is between 50,000-100,000 years.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

The youngest of these rocks are dated at about 220,000 years ago. Rhyodacties and quartz latites in the modern caldera area extruded from about 320,000 years ago to 260,000 years ago, and then silica-rich rhyolites at Glass Mountain northeast of the caldera erupted from about 210,000 years ago to 80,000 years ago. The scattered distribution of the initial mafic eruptions indicates that they were erupted from the mantle, while the slightly younger domes and flows were from a deep-crustal source. The youngest rhyolite eruptions erupted at the northeast rim of the caldera at Glass Mountain and were the first activity of the silicic Long Valley magma chamber (Bailey, et. al., 1989).

This celestial object was a comet, which slowly brightened over the next three weeks as it approached both the Earth and the sun.

This is an example of what the Mexicans faced when crossing the border to flee the violence as some have made it and the rest struggled to get to Texas. Texans imprinted other ridicule portrayals of Mexicans. In The Madisonville Meteor newspaper, one of the newspaper articles written by John W. Woodfuff, Debunking Popular Ideas of Mexico, also states how the Anglos stereotypically portrayed the Mexicans. According to Woodfuff, Texans believed that: “All Mexicans are naturally dirty and filthy and care very little for soap and water. All houses in Mexico are made of mud bricks, the ‘dobe’ huts we hear so much about. The whole country is one big desert with nothing but cactus and jack rabbits growing in it.

Volcanoes are some of the most powerful natural forces known to man. Volcanoes usually form at divergent and convergent boundaries. Sometimes they form in the middle of plates where magma fights through the crust. By understanding volcanoes, scientists get a window to the inside of the Earth. They can also study volcanoes to perhaps get closer to predicting eruptions in the future. One of Earth’s volcanoes is Clear Lake. Clear Lake has unique characteristics such as its location, how it forms, and how it erupts. It had erupted in the past with the potential to erupt again.

“Shoot for the moon. Even if you miss, you’ll land among the stars,” said Les Brown. Throughout the dream unit we have seen lots of videos of people who have achieved their dreams. But also of some people who didn’t achieve their dreams after they worked for it. But they ended up in the stars and were happy with what they did achieve. But just because some people don’t always achieve their dream doesn’t mean everyone can’t there’s a chance to achieve the dreams. But if we don’t we can still end up with part of the dreams or still achieve something.

Other planets do affect the comet's orbit as each planet has their own gravitational pull. That being

William Herschel was an amateur astronomer. “During the day his house was a school of music. Suddenly, it was a telescope factory as well. During the night it was an observatory” (Littman, 6). In 1781, while completing his “second all-sky survey with one of his home-made telescopes”, he saw something he couldn’t specify as a comet or a nebula.

Over the next six weeks, those watching the night skies are in for a wonderful treat. During those six weeks, we will be able to see several meteor showers from midnight to dawn in the Northern Hemisphere.

Introduction: Since the beginning of time, volcanoes have been wreaking havoc on the world, as we know it. Yet in the more recent times, there has been a great amount of debate regarding the effect of volcanic eruptions on world climate change. In this report, the effects of these volcanoes will be explored, particularly in regards to cooling and the depletion of the ozone.

Comets have two significant sources: The Oort Cloud, and the Kuiper Belt. The Oort Cloud is a cloud of icy objects that rests from 10,000 AU to 100,000 AU. Massive amounts of these icy objects remain in the cloud, cold and hidden from Earth. While these icy objects are still in the Oort Cloud, they are not yet comets - they lack tails and comae. Occasionally, the gravity of a star passing by may disrupt some of the bodies within the Oort Cloud, and the bodies will be pulled into the solar system where the sun heats them and they become comets. The second source of comets is the Kuiper Belt. The Kuiper Belt is a belt of icy planetesimals located beyond Neptune and the Jovian planets. It extends to about 50 AU from the sun. The Kuiper Belt orbits

Halley’s Comet crosses the Earth’s skies every 75 years. Samuel Clemens just so happened to be born following Halley’s comet, and in 1909, he predicted that he would go with Halley’s comet the next year. Clemens stated, “I came in with Halley’s Comet in 1835. Halley’s comet will be coming again next year, and I expect to go out with it” (Samuel Langhorne Clemens (Mark Twain) - Historic Missourians, n.d.). On April 21, 1910, one of the world’s most influential writers died. Just as he predicted, he passed the night after the comet lit up the sky at the age of 75. Mark Twain, born Samuel Langhorne Clemens died from a severe heart attack. He changed his name to Mark Twain because he loved to be in the water and on sailboats. On the Mississippi River, ' Clemens ' meant 'two fathoms deep. ' He never thought that his age made a difference in his life. He always mentioned, “Age is an issue of mind over matter. If you don 't mind, it doesn 't matter” ("Samuel Langhorne Clemens (Mark Twain) - Historic Missourians, n.d.). He was always optimistic about death and old age.
