During this period‚ Earth was nothing but molten rock from the collision with other bodies and volcanoes‚ temperature reaching over 2‚000 fahrenheit. Not only that‚ but Earth then‚ would’ve been toxic to humans and modern life because of the lack of oxygen. Only carbon dioxide and nitrogen were presented and some water vapor. One massive planetary

When I was eight years old‚there were some woods behind our house and in those woods was a dirt road that led to an abandoned sand quarry‚ complete with a sloping wall of top soil‚ which in winter became a pretty big and steep snow hill‚ for a ten year old anyway. With every fresh snowfall this hill immediately attracted every youngster in the neighborhood‚ time and time again we would climb up with toboggan in tow‚ position ourselves at the crest of this marvelous mound of merriment and launch

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night (the diurnal temperature variation).The common name given to the atmospheric gases used in breathing and photosynthesis is air. Dry air contains roughly (by volume) 78.09% nitrogen‚ 20.95% oxygen

Save the Earth With all the talk about going green‚ it seems much easier to let the cards fall where they may. What’s easier? Just throwing all the trash into one can‚ or sorting it into separate cans? As hard as it could be to clear the mess that this and past generations have left‚ it would be severely healthier than the alternative. Plutonium is a dangerous toxin that is released from nuclear power plants. “Plutonium‚ which has the half-life of only 0.5 million years‚ but is so toxic that
