The four forces of evolution are natural selection‚ mutation‚ genetic drift‚ and gene flow. Natural selection has to do with adaptation. It preaches that those species that have better adapted to the environment with various traits and just simply their behavior‚ will be stronger and therefore able to survive for longer periods of time and allow for their genes to continuously be passed on to the next generations of that species. Mutations have to do with adding‚ subtracting‚ and deleting of nitrogen

Continental drift has helped create the diversity we see present in modern day plants and animals. Through a process of speciation‚ the movement of the continents has had a generous role throughout evolution‚ effecting and distributing flora and fauna. The Earth’s continents were once one‚ a large supercontinent called Pangea that later separated into two smaller ones known as Gondwana and Laurasia. The separation and collision of continents has not only created some of the valleys and mountain ranges

chlorine or bromine atoms to form chlorine monoxide or other chemicals‚ which would deplete upper-atmospheric ozone. A seasonal decrease‚ or "hole‚" discovered in 1985 in the ozone layer above Antarctica was the first confirmation of a thinning of the layer. The hole occurs over Antarctica because the extreme cold helps the very high clouds characteristic of that area form tiny ice particles of water and nitric acid‚ which facilitate the chemical reactions involved. In addition‚ the polar

The "hole" is located over Antarctica. It covers an area about the size of the United States. Experiments done in Antarctica show that the hole in the ozone layer appears to let in twice as much ultraviolet radiation ans

Ozone depletion Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’sstratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as the ozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polar tropospheric ozone depletion events. The details
