Study Notes
Layers of the Atmosphere
-
Troposphere
- First layer of the Earth's atmosphere.
- Extends from sea level up to 0-12 kilometers.
- Temperature decreases with altitude, becoming colder at higher elevations.
-
Stratosphere
- Second layer of the atmosphere, reaching up to 50 kilometers.
- Contains the ozone layer, which absorbs and protects against harmful ultraviolet radiation.
- The temperature increases with altitude due to ozone absorption of sunlight.
-
Mesosphere
- Third layer, extending from 50 kilometers to 80 kilometers above Earth's surface.
- Known as the coldest layer, with temperatures dropping to around negative 90 Celsius.
- Temperature decreases with altitude, making it increasingly frigid.
-
Thermosphere
- Uppermost layer of the atmosphere, starting at 80 kilometers and extending into space without a defined limit.
- Characterized by very thin air and extremely high temperatures, reaching up to 1,800 Celsius.
- Solar radiation first strikes this layer, significantly heating it.
