Study Notes
Layers of the Atmosphere
- Earth's atmosphere is divided into four main layers: Troposphere, Stratosphere, Mesosphere, and Thermosphere.
Troposphere
- Closest layer to Earth's surface, extending up to approximately 8 to 15 kilometers high.
- Contains the majority of the atmosphere's mass and is where most weather occurs.
- Temperature decreases with altitude, leading to the formation of clouds and precipitation.
Stratosphere
- Located above the Troposphere, reaching heights of about 50 kilometers.
- Home to the ozone layer, which absorbs harmful UV radiation from the sun.
- Temperature increases with altitude due to the absorption of radiation by the ozone.
Mesosphere
- Extends from about 50 kilometers to 85 kilometers above the Earth.
- This layer is where temperatures again decrease with altitude, reaching the coldest temperatures in the atmosphere.
- Meteors burn up in this layer, creating meteor showers.
Thermosphere
- Ranges from approximately 85 kilometers to 600 kilometers above the Earth.
- Characterized by a significant increase in temperature with altitude, due to solar activity.
- Contains the ionosphere, which is important for radio communication and the reflection of radio waves.
Exosphere
- The outermost layer of the atmosphere, starting around 600 kilometers above the Earth.
- Composed mainly of extremely thin air; atoms and molecules can escape into space.
- Contains satellites and is where the atmosphere transitions into outer space.
