Atmosphere One of Our Six Spheres

Revisit Spheres Name the six spheres of our planet. – Lithosphere – Hydrosphere – Cryosphere – Atmosphere – Biosphere – Celestial sphere Revisit Spheres

?Essential Question? What are the separate spheres of our atmosphere? How do the mechanics of our atmosphere operate? What are some impacts from humans on our atmosphere?

SWBAT Analyze several types of atmospheric diagrams created from different perceptives. Understand the propreties and mechanics each layer exibits. Recognize and offer solutions of the human impact on our atmosphere. Score in a specific time range on a speed game.

Atmosphere The surrounding air of the Earth

Layers of the atmosphere There are ?4 layers? in the atmosphere They are the troposphere, stratosphere, mesosphere, and thermosphere Exosphere Tropopause Mesopause Stratopause Celestial Sphere/Space

Troposphere This is the layer that is closest to the surface of the earth It’s elevation ranges from 0 to 10 km up to 20 km.

Stratosphere This layer sits on top of the troposphere It’s elevation ranges from 10 km to around 25 km This layer contains the ozone layer, which protects us from harmful sunlight

Mesosphere This layer is above the stratosphere It’s elevation ranges from 25 to 100 km

Thermosphere This is the highest layer of the atmosphere It’s height ranges from 100 to 400 km This is where most small meteorites burn up and is also the location in the atmosphere that the northern lights occur (aurora borealis)

Composition of Air There are many different types of gasses in the atmosphere They include nitrogen, oxygen, argon, carbon dioxide and other noble gasses The gas that is most abundant is nitrogen

What % of CO2 do humans produce? Nature produces nearly all of it. Humans produce only 3%. As a decimal it is a miniscule 0.001% of the air. All of mankind produces only one molecule of CO2 in around every 90,000 air molecules! Yes, that’s all.

CO 2 is an asphyxiant and not classified as toxic or harmful in accordance with Globally Harmonized System of Classification and Labeling of Chemical Standards of the United Nations Economic Commission

In concentration of 0.5% to1% (5, ,000 ppm) will make some people feel drowsy and lethargic. Concentrations of 7% to 10% (70,000 – 100,000 ppm) may cause suffocation Or, manifesting itself as dizziness, headache, nausea, visual and hearing dysfunction, and unconsciousness within a few minutes to an hour leading to death.

Is CO2 is a pollutant? The Correct Answer: CO2 is a harmless, trace gas. It is as necessary for life – just as oxygen and nitrogen are. It is a natural gas that is clear, tasteless and odourless. It is in no way a pollutant.

Major gases on the overall greenhouse effect Water vapor H 2 O 36 – 72 % Carbon dioxide CO 2 9 – 26 % Methane CH 4 4 – 9 % Ozone O 3 3 – 7 % Nitrous oxide Perfluorocarbon and Hydrofluorocarbon Sulfur hexafluoride

Outgassing is the release of a gas that was dissolved, primarily in the oceans and/or trapped, frozen or absorbed in ice or rock. Outgassing can include sublimation and evaporation which are phase transitions of a substance into a gas

Polar Clouds: PSC’s andPMC’s

Clouds All within the Troposphere Clouds are found “almost” exclusively in the troposphere.
