intense volcanic activity and the effect of plate tectonics. The second theory is known as Extrinsic Catastrophism and proposes that the K-T Extinction was caused by a sudden and violent catastrophic event such as the Earth being struck by a meteor or asteroid. The K-T Extinction supports the concept of Punctuated Equilibrium in evolution because surviving species evolved and others were exterminated. This creates the stepladder effect of evolution seen in the fossil record . THE K-T EXTINCTION The

In the article titled “Meteor likely caused the Earth’s Greatest Extinction Event” the author states that “About 60 meteorites five or more kilometers across have hit the earth in the past 600 million years. The smallest ones would have carved craters some 95 kilometers wide. “Most scientists agree that one such impact did in the dinosaurs‚ but evidence for large collisions coincident with other mass extinctions remained elusive until recently.”The increased attention brought about the discovery

Why do the planets have different colours? The answer is that the planets are different colors because they are made of different materials. Planets have the colours that they have because of what they are made of and how their surfaces or atmospheres reflect and absorb sunlight. Mercury has a dark grey‚ rocky surface which is covered with a thick layer of dust. The surface is thought to be made up of igneous silicate rocks and dust. Venus is entirely covered with a thick carbon dioxide atmosphere

In scientific jargon the term “chaos” does not carry a negative connotation‚ instead the unpredictable behavior that it relates with is desirable. The Chaos Theory is a mathematical
