Hydrosphere/Atmosphere

Transcript

1. The moving systems *
2. * *All water on Earth *Makes Earth special *Water exists in all states *Only planet to be able to support life because it contains water
4. *Cryosphere is a part of the hydrosphere *Made of the Ice *About 3% of the Hydrosphere *
5. * *Main Interactions through water cycle *Hydrosphere is very dynamic and open system *Water evaporated in atmosphere is water vapor *Always moving watercycle
6. *Hydrosphere is essential for life *Fresh water is a limited resource *People affect water sources, water management is an ongoing challenge *
7. * *How does water and the water cycle affect you here where you live?
8. * *Gasses surrounding the Earth *Extends hundreds of miles *Wind is movement of the air in atmosphere
9. * *No distinct end *Merges with space *Mostly Just oxygen and nitrogen *Some Argon and very little Carbon Dioxide *Greenhouse gas that traps heat!
10. * Write into your notes and then share with a partner * If Carbon Dioxide traps heat, explain what happens if there is more of it in the air .
11. * *Troposphere *Where weather and life happens *Stratosphere *Where airliners fly *Ozone layer is located here *Mesosphere *Charged with Ions, burns up meteorites *Thermosphere *Very thin, turns sunlight to Northern Lights *Exosphere – Merging with space
12. * *Serves as a fliter from Sun’s ultaviolet radiation *absorption of ultraviolet radiation by ozone creates a source of heat *Depletion- decrease *Caused by green house gases (CO2 , CO, CH4 ) and chemicals in refrigerators, air conditioners, cleaning of electronic equipment, and more * results in holes in the Ozone layer Ozone Depletion
13. *Provides Oxygen and CO2 essential for human and plant life *Protects from sun’s harmful radiation *Controls climate *Open system transfers through water and carbon cycles *We need to be careful of CO2 we put in *
