1. Exosphere: The outermost layer, extending into outer space.
2. Thermosphere: Characterized by increasing temperature with altitude due to absorption of solar radiation.
3. Mesosphere: Temperature decreases with altitude, where meteors burn up.
4. Stratosphere: Contains the ozone layer, which absorbs harmful ultraviolet radiation from the sun. Temperature increases with altitude.
5. Troposphere: The lowest layer, where weather occurs and most of the atmosphere's mass resides. Temperature decreases with altitude.
