Layers of the Atmosphere (Animation)

This video transcript discusses the five main layers of the Earth's atmosphere: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. It explains the composition of each layer, the boundary between them, and the temperature versus height. It also mentions the protective ozone layer in the stratosphere and how meteors burn up in the mesosphere. It further explains why the temperature in the atmosphere varies with altitude, with the troposphere having the warmest temperatures due to the absorption of radiant energy from the sun, the stratosphere being very dry and having ozone which absorbs short wave-ultraviolet radiation, the mesosphere being the coldest layer due to the low air density and cooling effect of carbon dioxide, the thermosphere being hot due to radiation from the sun, and the exosphere being very hot during the day and cold at night due to the thin air.
