Document Summary
Which of the following is the most abundant gas in the earth"s atmosphere: oxygen, carbon dioxide, nitrogen, hydrogen, water vapour. The layer of the earth"s atmosphere in which weather occurs is the: hydrosphere, troposphere, stratosphere, ionosphere. Scientists think the earth"s core is composed mainly of: silicate rocks, lead, uranium, iron, sulfur. Simply put the greenhouse effect is, a myth made up by the government. The atmosphere shrinking as the dense co2 falls and the less dense n2 rises creating a super conduction pushing hotter air downwards towards the earth surface. Co2 released by plants causing the air to become more dense in turn creating higher temperatures. When infrared light from earth"s surface is captured by gases like carbon dioxide in the atmosphere and re-radiated in all directionsheating the surface. We see very few craters on earth"s surface because. Our large moon shields us from most potential impacts. The earth"s thick atmosphere causes incoming rocks to burn up above the surface.
