More evidence to support this theory is that the layers of the rocks: the upper layer which contained soot which they believed came from global fires caused by the impact of the asteroid and the lower layer which contained quartz crystals and tektites which are found on asteroid impact sights. To add to this theory in 1990 a scientist Alan Hildebrand noticed a ring structure called CHICXULUB in Mexico which was a crater of 180kilometers in diameter and dated from around 65million years ago, the same time as the extinction of the dinosaurs. It was estimated that an object 10kilometers in diameter would have caused the crater and this fits in with Luis and Walter Alvarez’s calculation about the size of the asteroid that would have created the rock find. c) What evidence is there that discredits your theory? Palaeontologists have yet to find dinosaur fossils dating to the time off the impact.
Target Earth: Asteroid and Comet Impacts by Philip Plait discusses issues involving what effects meteors, meteoroids, meteorites, asteroids, and comets have on Earth. Earth gets hit by twenty to forty tons of meteors every day. Most of it is detritus, a material made up of small rocks that burn up in the atmosphere. Detritus is what we see when we see a "shooting star". The big question is; how is something so small, so bright?
Said O'Keefe: If tektites are terrestrial, it means that some process exists by which soil or common rocks can be converted in an instant into homogeneous, water-free, bubble-free glass and be propelled thousands of miles above the atmosphere. If tektites come from the Moon, it seems to follow that there is at least one
Because Titan has such a dense atmosphere scientists had a lot of trouble studying the surface of the large moon. This was until 2004 when the CassiniHuygens mission was launched. The purpose of this mission was to observe and study Saturn and Titan by using fly-bys. The fly-bys that have already taken
Through reflection, the sun's light allows you to see what you see as the moon. We see phases because the moon itself rotates while traveling around the Earth at the same time. it just is Moon phases are the different forms the Moon takes in its appearance on earth. A full moon occurs when the moons surface reflects light towards Earth. A Waxing moon is when more of the light side of the moon can be seen each night.
This causes the comet to brighten enormously. Sometimes this develops a brilliant tail, extending millions of kilometers into space. Even as the comet recedes again, the tail is directed away from the sun. What are these spectacular comet tails composed of? Comet tails are made up of simple ionized molecules, including carbon monoxide and dioxide.
Unit 10 WA: The Solar System Discussion Questions: 1, 2, 3, 5, & 8 1. Was the formation of Earth unique, or was it similar to the process that created all the planets in the solar system? It was made the same way the other planets were made. All the planets and galaxies were made during the Big Bang. 2.
The flat earth theory describes the earth as being a floating disk with another disk above us that contains stars, planets, and the moon and is constantly rotating. It describes the disk with stars to be “not super far” unlike the round earth theory that makes stars like polar several light years away Round Earth model Flat Earth Model Our experiment consists of measuring the angle of Polaris and the horizon line in different places in Utah with a sextant. We then graphed the information to find the relationship to the equations that each theory has. My hypothesis is that the round earth theory will have an inverse and linear relationship and the flat earth theory will have an inverse and non-linear relationship. We can see this to disprove the flat earth theory.
“Fundamental to the conspiracy theory is our supposed inability to go to the Moon. The thought of humans traveling to the Moon was so fantastic even early science-fiction writers didn't predict it happening for centuries to come”(Villard). The rockets that made the moon landing possible were based upon the principles that were founded by Isaac Newton centuries ago, meaning that the underlying science was already there. The Saturn V rockets were more than capable of taking a man to the moon, and it was seen by thousands of eyewitnesses and media who saw the rocket blast off from the Kennedy space center in Florida (Villard). Those who claim that NASA could not reach the moon in the 1960’s discredit the hardworking engineers and scientists who paved the way for a lunar
