The Atmosphere– layer of gas that surrounds Earth more commonly known as “ air ”.

Even though you can’t see them, Atoms make up gases. ,[object Object],[object Object]

Helium vs. Carbon Dioxide Do you think of helium as light and floating or heavy and falling? Do you think about Carbon Dioxide as light and floating or heavy and falling….think about the gas released from dry ice… does it go up or down? http://jp.youtube.com/watch?v=F239cINIADs

Atmosphere Exosphere-- Thermosphere-- Mesosphere- Stratosphere-- 10 km to 50 km , contains ozone that absorbs much of the Sun’s ultraviolet radiation. , Gets warmer as you go up. ,[object Object]

Atmosphere Exosphere-- Thermosphere-- Mesosphere- 50-85 km, The coldest part of the atmosphere. It can get down to -90°C in the mesosphere. - Stratosphere-- 10 km to 50 km , contains ozone that absorbs much of the Sun’s ultraviolet radiation. , Gets warmer as you go up. ,[object Object]

Atmosphere Exosphere-- Thermosphere-- 80-500 km, Temperatures increase up to 1,700°C, Filters out x-rays and gamma rays from the sun. , This is an image of the space shuttle as it is orbiting around the Earth. The space shuttle orbits in the thermosphere of the Earth. Mesosphere-- The temperature drops when you go higher, like it does in the troposphere. Coldest part of the atmosphere Stratosphere-- from 10 km to 50 km above Earth’s surface, this layer contains ozone that absorbs much of the Sun’s ultraviolet radiation. ,[object Object]

Exosphere ,[object Object],[object Object],[object Object]

Atmosphere Exosphere-- The last layer of the atmosphere, Difficult to tell where it stops and space begins, Very few atoms in this layer of the atmosphere Thermosphere-- The air is really thin that high up. The temperature changes with the solar activity . If the sun is active, temperatures in the thermosphere can get up to 1,500°C or higher! Mesosphere-- The temperature drops when you go higher, like it does in the troposphere. Coldest part of the atmosphere Stratosphere-- from 10 km to 50 km above Earth’s surface, this layer contains ozone that absorbs much of the Sun’s ultraviolet radiation. ,[object Object]
