Water vapor, CO2, CH4, N2O, and SO2 all have an important property: They absorb heat emitted by Earth and thus warm the atmosphere, creating what we call the "greenhouse effect." ... These charged particles are useful for communication and because at night they reflect radio waves. During the day, radio reception is terrible over long distances because the waves are absorbed. ... However, the thermosphere would actually feel very cold to us because of the probability that these few molecules will hit our skin and transfer enough energy to cause appreciable heat is extremely low. ... Heat is tr...

The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. ... The increases of temperature could alter the growth of crops in areas near the equator due to insufficient rain and heat. ...

Without these gases, heat would escape back into space and Earth's average temperature would be about 60 ∘F colder. ... It is penetrated by short-wave radiation from outer space but blocks the escape of long-wave radiation. As increased quantities of CO2 are added to the atmosphere, the shield thickens and more heat is retained, increasing global temperatures. ...

Not only that but at the moment in time in which we discovered the sun was gone, we would lose its gravitational influence, "and Earth would fly out in a straight line tangent to where ever it was in its orbit" () This is because gravitational force propagates in waves moving at the speed of light. ... Without the enjoyable warmth of the sun, the Earth would lose heat exponentially at first but slowly decrease as time went on. ... This is because the Earth produces its own heat. ... With approximately a mile of ice insulating the Earth from space, and the underwater volcanic vents s...

Global warming is the result of humans releasing heat-trapping gases into our atmosphere to power our modern lives. ... This causes the Earth to get warmer and warmer, because the gases trap heat. It is like putting the Earth in a green house, because the gases let light in, but keep heat from escaping. ... There has been extreme weather events such as heat waves, droughts, floods, and wild fires. ...

"The sun emits short-wave radiation which passes through the atmosphere to Earth. The Earth then radiates some of the sun's energy back into the atmosphere in the form of long-wave infra-red radiation." Since the atmosphere is primarily composed of nitrogen and oxygen and does not retain heat, gases such as carbon dioxide, methane, ozone and nitrous oxide trap some of the infra-red radiation. ...

The sun is 93 million miles away from earth and its energy travels to us in moving waves called radiation. The energy becomes heat, light and other energy too. ... These rays can't be seen, but some can be felt as heat. ... The effect is like when a greenhouse traps heat, which is where we got the name greenhouse effect. ...

Methane producing bacteria could have a profound effect on the atmosphere of the early Earth, producing strong absorption in mid-infrared at a wave number of 1300 cm. ... Other characteristics to watch for when mixing two or more substances are heat and light, flames, explosion, color change, and evolution of gas. ...

ACID RAIN ACID RAIN "Statues dissolving and guns rusting, children choking and soil becoming poisoned, trees withering, rocks blackening. And the trout float belly-up" (Pawlick 184).
