What are the percentages of the gases that make up our atmosphere?
Autor: yxng.edxnRespuesta:
78% is nitrogen. This is important for plant growth. 21% is oxygen. This is breathed in and out by animals and plants. 1% is water vapour. This forms clouds and is essential for the water cycle. 0.04% is carbon dioxide. It regulates temperature and plants breath it in. Methane and CFC's are other minority gases.
