iridium evidence at many different locations around the world that supported the Alvarez theory. In 1991, an immense meteor crater, about 110 miles in diameter, was discovered on the the Yucatán Peninsula. The crater even extended to the Gulf of Mexico. The Chicxulub Crater, as it was called, was named after a nearby village. Scientists believe the meteor that formed this massive crater was around 6 miles in diameter. It is also believed that it struck the earth at 40,000 miles per hour and released 2 million
fate. This discovery was the Chicxulub crater in Yucatan, Mexico. The claim was that this 180 kilometer crater was the impact scar left by an asteroid that collided with the earth. The asteroid was so large and landed with such force that it effectively ended the dinosaurs reign over the earth. However, recent evidence and research reported in Proceedings of the National Academy of Sciences suggests that this could not have been the case, because the Chicxulab crater predates the mass extinction
Hildebrand, an associate professor at the University of Calgary, discovered the Chicxulub crater on the Yucatan peninsula in Mexico. This crater was 186 miles in diameter and six miles deep, and it was created when an asteroid hit the Earth approximately sixty-five million years ago. This asteroid is said to have strike the Earth with a force of 100 million to 300 million megatons of TNT (Recer 1993). With the discovery of the crater came the theory that this particular asteroid killed the dinosaurs and
Theories on Dinosaur Extinction What killed the dinosaurs? Several theories have been brought up over time to answer this question. It has been of vast interest to many scientists how creatures the size of the dinosaurs could have been wiped out of existence. Proposed Theories Climate Change Theory Some scientists propose that climate change was killing the dinosaurs before the famous asteroid struck. Fossil evidence shows that the average temperature had dropped from 25 degrees Celsius

The theory that's been branded into our minds was that a single asteroid involves the Chicxulub crater in Mexico's Yucatan Peninsula.

Why cant we just except that they were wiped
Craters Investigation In this experiment I am going to investigate one factor that causes craters to be different sizes. I am going to do this by dropping a ball bearing with a mass of 63.7g, from varying heights into a tub of sand and then measuring the width of the crater it made. Research -------- On the Moon, craters usually measure up to 200 (320 miles) or more in diameter. Meteorites hitting the lunar surface at high velocity produced most of the large craters. Many of the
on Mercury and at the bottom of the craters and basins. The hottest are the places closest to the sun. The temperature of the side that is farthest away from the sun is allot warmer than scientists thought it would be. Not a whole side but parts of Mercury have never been in sunlight before. This is why scientists thought it would be colder than it really was. Mercury’s surface is much like the moon, they are very colse to being the same size. It has many craters, high multiple ring basins, and many
Venus is the second planet from the sun and the sixth largest. Venus’ orbit is the most circular of any planet, with an eccentricy of less than 1%. Venus, perhaps because it is the brightest of planets known to the ancients, Is named after the Greek goddess of love and beauty. The planet of Venus has been known since prehistoric times and is the brightest object in the sky with the exception of the sun and the moon. Venus’ rotation is somewhat unusual in that it is both very slow ( 243
Mars is the fourth planet from the sun at about 228 million-km (141 million miles) and the last terrestrial planet from the sun. The next five planets in order from the sun are gaseous. Mars follows closely behind Earth but is comparatively smaller, with about half the diameter of Earth and about one-tenth of Earth’s mass. Thus the force of gravity on Mars is about one-third of that on Earth. Though it is much smaller, Mars does have the same surface land area as Earth. Other than Earth
surface. most of the rivers are too shallow and steep to be navigated. Their waters are used to irrigate farmland, and their rapids and falls supply power for hydroelectric plants. Many lakes nestle among the Japanese mountains. Some lie in the craters of extinct volcanoes. A large number of hot springs gush from the ground throughout the country. The Japanese islands have a total land area of about 337,708 sqkm. The islands , in order of size, are Honshu, Hokkaido, Kyushu and Shikoku. The sea
believed in the Copernican system. When Galileo pointed his telescope to the sky, he made many discoveries that confirmed the Copernican system. One thing he found was that the moon was not a perfect sphere as thought of in the Ptolemaic system; it had craters and mountains not visible to the human eye. Another d...
of nickel and iron. Most big asteroids are ball shaped. Smaller asteroids, which are usually broken off of a larger asteroid, come in a lot of different shapes. All asteroids have craters that form when they bump or crash into other asteroids. The older the asteroid, the more times it has been hit and the more craters it has. Asteroids can be found orbiting the Sun in a belt between Mars and Jupiter; this is called the Asteroid belt or Main belt. The asteroid belt has been said to probably contain
describes the darker part of the moon which was suffused with “earth shine”. The light which the moon received from earth was much intense and bright than the moon light visible from earth. Therefore, they could easily view the mountains and the craters in the earth light. Stars embellished the sky, ahead and above them, with their “icy fire” and an “arc of impenetrable darkness blotted the firmament”. Then at dawn “barely discernible streamers of light” gradually illuminated the moon. Then within
Defense Clementine spacecraft shows that there maybe water ice in some deep craters near the moon's North and South Pole that are permanently shaded. Most of the moon's surface is covered with regolith, which is a mixture of fine dust and rocky debris produced by meteor impact. There are two types of terrain on the moon. One is the heavily cratered and very old highlands. The other is the relatively smooth and younger craters that were flooded with molten lava. Throughout the 19th and 20th centuries
with the telescope has to be Galileo. He took the design and reinvented the telescope into one of the first refractive telescopes we use to this day. Galileo used this great invention to report astronomical facts such as the moon is cover with craters instead of being smooth, the Milky Way is composed of millions of stars, and Jupiter have four moons. Perhaps the most famous discovery is the Earth revolves around the Sun and the Earth is not the center of the universe (even though he was discredited
character. My first example is as Mr.Shiftlet enters the story. At first he appears to the reader as innocent and pitiful. He shows an emotion to the reader as him being portrayed as helpless, innocent, and as a cripple. Mr.Shiftlet later questions Mrs. Crater why she trusts him stating, “…you never have seen me before: how you know I ain’t lying?” again appealing to his innocent appearance. Mr.Shiftlet’s helpless and pitiful character shows those around him believing that he is trustworthy. Another example
cinematography. Scripts for most of the episodes were borrowed from the famous novels. Jules Verne's "From the Earth to the Moon" provided the image of the space capsule and giant cannon; most of the lunar episodes with blizzard, descent to the lunar crater, battle with selenites, arrival to the ocean bottom, were taken from "The First Men in the Moon", written by Herbert George Wells. The clarity and completeness of the plot, the vibrant costumes and decorations, and the special effects in "A Trip to
Impact Craters Space is frequently referred to as the final frontier due to the fact that much of it is yet to be studied. If society is able to explore the vast expanse of space it will most definitely reveal possibly thousands of previously unknown ideas, theories, and technologies. Even though much of space is unexplored and unstudied, certain fields of study are easier to investigate and analyze, providing society with a sizeable amount of information. One such area of study that is relatively
this experiment throws a ball's with diffrent weight directly downwards to a box full of sand. As the weight of the ball increases, the size of the impact crater changes, assuming the ball is always dropped from the same height as measured from the top of the sand box to the bottom of the ball. The reason behind this experiment is to determine the relationship between the mass of the ball to size of the impact it made on the sand. The size of the impact is the dependent variable, the mass of the
“Between both our meteor fragments, we have an adequate amount of Reidite [the high-pressure Polymorph important in shock metamorphism], for a true assessment.” Boniface lights up his pipe, with a somber expression he places his feet on the desk, with the potential that he holds in his hands, he observes the sparkling qualities of the Reidite. “It will work,” he explains to his colleague. Boniface reminds Lawton, there are only three impact structures on earth. “Although destructive,” Boniface adds
