Layers of the Atmosphere Notes

Layers of the Atmosphere Divided depending on Temperature

Lower Layers of Atmosphere Troposphere: lowest layer – extends up to 10km; contains 99% of the water vapor and 75% of the atmospheric gases The troposphere.

Earth’s Atmospheric Layers. Troposphere Distance above sea level: 0-16 km Average Temperature: -50º to 70º F All weather happens here. Warm air rises.

Layers of Earth’s atmosphere. How was the atmosphere formed? Atmosphere has changed (evolved) over time. Gases are held near the surface by gravity. Earth’s.

Troposphere About 75-80% of the atmosphere’s mass Rises to about 20km or about 7.5 miles Air is warmest at the bottom and gets colder as you move.

The Atmosphere

Structures of the Atmosphere The atmosphere is separated into layers based on temperature Layer Distance above Earths Surface Average Temperature Description Troposphere 0-16km 20 to 500C -ALL weather -water vapour -Increase altitudes causes drop in temperature Stratosphere 16-50 km 100C -ozone rich -dry layer -increase altitude causes increase in temperature

Structures of the Atmosphere continued… Layer Distance above Earths Surface Average Temperature Description Mesosphere 50-80 km -750C -middle layer -meteors burn up here Thermosphere 80-500 km 300C (absorbs x-rays 6000C -Ionosphere (sun’s energy electrically charges particles) -Aurora’s -allows radio transmission Exosphere 500 km ++ ---------------- -”space” -few particles/spread out -satellites orbit here
