• The earth's atmosphere is a colourless,odourless and tasteless mixture of gases.
• Nitrogen constitutes 78 percent and is the most abundant gas.It helps in maintaining soil fertility and promotes growth of animals and plants.
• Oxygen constitutes 21 percent and is the most important gas for the survival.It helps in respiration.Green plants produce oxygen during the process of photosynthesis.
• Carbon dioxide constitutes 0.03 percent and is essential for the survival of plants.During photosynthesis they take in carbon dioxide that the humans and animals produce during respiration.
• Apart from these other gases,water vapour ,dust ,smoke,pollen and even salt particles are found in lower limits of atmosphere.
