How Many Layers of Atmosphere on Earth?
The earth’s atmosphere is the layer of gasses, commonly known as air, that surrounds the Earth and is possessed by gravity of earth. The climate on Earth is life-supporting by penetrating UV solar radiation, warming the surface through heat absorption (greenhouse effect), and reducing temperature rise during day and night. […]
