themselves are we safe from an asteroid that is going to impact the earth? How can we defend our planet from some uncontrollable events of nature? According to NASA the US congress has made a deep investigation on the impacts of 1993‚ 1998‚ and 2002. In 1998 NASA created a program (NEO Program Office) an organization that spends between $3-4 million per year. This organization searches for large object that may approach earth resulting in an impact. But can we defend ourselves from such situation? Some

Stephen Jay Gould‘s (2002) essay: Sex‚ Drugs‚ disasters‚ and the Extinction of Dinosaurs‚ investigates dinosaur extinction theories. According to Gould‚ scientific conclusions are the consequence; not the essence. Gould believes science’s main problem is the failure to separate fascinating claims from the scientific methods used‚ stating that “…science is‚ basically‚ a way of knowing” (pg.267). Gould examines three proposed ideas of dinosaur extinction. They are sex‚ drugs‚ and violence. Since

Other scientists however‚ believe that it could have been a UFO crash‚ a natural hydrogen bomb‚ and some people at the time of the event believe it was the end of the world. The force of the impact that hit the Earth was estimated between 5 to even 30 megatons. That is as much force as that produced by the Castle Bravo Thermonuclear Bomb detonated by the United States. Recent findings at the site of Tunguska event might help scientists

Introduction Law is a system of rules and guidelines which are enforced through social institutions to govern behavior‚ wherever possible. The law of contracts differs from other branches of law in a very important respect. It does not lay down so many precise rights and duties which the law will protect and enforce. Instead‚ the law of contract is a division of law which contains rather a number of limiting principles‚ subject to which the parties may create rights and duties for themselves‚ and

formed in sand as a result of the impact. By Ivan Cocklove Design Defining the problem and selecting the variables: I will investigate how the height from which a mass falls onto flat surface of sand affects the radius of the crater formed as a result of the impact. The height from which the ball is dropped is affecting the speed at the impact because the higher the drop‚ the longer the ball will have to accelerate‚ therefore the higher the velocity at the impact will be. The formation of craters

dinosaurs is still a mystery today but their are many theories supporting how and why approximately 70% of all living species on earth suddenly became extinct including dinosaurs‚ 66 million years ago. The most common and realistic theory is the astroid impact theory when a astroid 6-15 km in diameter hit earth with the force of five billion atomic bombs. Another possible theory is climate change‚ the dinosaurs didn’t adapt fast enough to the climate when it was changing and eventually they became extinct

Crabbe thought he was totally prepared to live on his own from his point of view‚ but from nature’s point of view‚ he was never really prepared the day he had set out from the lack of his inexperience. Therefore‚ Crabbe learns that nature has a bigger impact on one‚ than it might look. Second‚ Crabbe learns that if he were to live off on his own in nature‚ without Mary‚ he would die in a matter of a few weeks. Crabbe learns that the basic essentials of life are still needed to live in the wilderness

crater. Scientific knowledge Impact craters are geologic structures formed when a large meteorite‚ asteroid or comet smashes in to a planet or a satellite. Meteorites are small rocks in space that hit the earth’s atmosphere at a high velocity. Throughout their history they have heavily bombarded all the inner bodies in our solar system. In this experiment we will use marbles as our meteorites‚ these will be free falling objects that will be used to copy an asteroid impact. The surfaces of the Moon‚
