- The air in the atmosphere is about 78% nitrogen and only 20 % oxygen
- Another hypothesis is that since the earth has changed orbit in so many different ways this causes changes in solar radiation.
- Scientists believe that volcanic material is used to reflect some of the suns material and cause a cooling in temperature.
- green house gases include CO2, Methane, and Nitrous oxide
- Water vapor also plays a big role in climate change because it also absorbs the heat from the sun and also it varies by region.
- The atmosphere moves constantly which causes small materials to get trapped in it such as volcanic ash.
- One hypothesis is that when the earths continents move on the plates this causes a great fluctuation in the weather.
