Chapter 4.1- Earth’s Atmosphere Pages 90-97

Earth’s Atmosphere Atmosphere- a thin protective layer of air that surrounds the Earth and makes life possible Atmospheric Gases: 78% Nitrogen, 21% Oxygen, 1% other gases Solids: dust, salt, pollen Liquids: water

Troposphere Lowest layer Where I live Weather occurs here Contains 99% of the water vapor found in the atmosphere & 75% of atmospheric gases Extends 10 km above Earth’s surface (6.2 miles) Higher you go the colder it gets

Stratosphere km above Earth ( miles) OZONE LAYER that protects us from sun’s UV rays is found here Planes and jets fly here The higher you go the warmer it gets because of the ozone layer

Mesosphere km above Earth (31 – 53 miles) Meteors burn up in this layer b/c of friction with air particles (called shooting stars) Temperature decrease as you go higher in the mesosphere (COLDEST LAYER)

Thermosphere thickest layer of the atmosphere km above the earth's surface (53 – 310 miles) very high temperatures C auroras, northern lights Ionosphere – located here, a layer of electrically charged gas particles which allows radio waves to travel across the country

Exosphere outermost layer of the atmosphere 500 km - outer space (310 miles & beyond) few molecules exist in exosphere and thermosphere they have extremely high energy & temps because 1st layer to receive the suns energy space shuttle and satellites so few molecules that the wings of the space shuttle are useless it uses rocket launchers Jason-2 satellite carries tools & sensors to help study ocean.

“pauses” of the atmosphere -boundaries of the layers 4 pauses that occur AFTER that layer 1. Tropopause 2. Stratopause 3. Mesopause 4. Thermopause

Temperature Differences in the Atmosphere The layers of the atmosphere are broken up based upon differences in temperature. Let’s practice reading this graph… 1. What layer does the temperature reach -90 o C 2. If you are at an altitude of 70km, what layer would you be in? 3. What layers does the temperature decrease with altitude? 4. What layers does the temperature increase with altitude?
