1. Review

2. Scientific Method

3. Atmosphere
Trosphere
Stratosphere --- ozone
Mesophere
Thermosphere

4. Earth’s Sphere Hydrosphere --- water on earth
Litosphere --- crust and rocks
Atmosphere --- gases above earth
All life is from the top of the litospher to the bottom stratosphere

5. Earth’s Regoions

7. Heat Transfer Conduction - touching Convections – winds and currents
Radiation- electromatic waves
Energy is from the sun
Heat (hot air) rises

8. Water Cycle Evaporation Condensation Perception Runoff Transpiration
Dew– at time of condensation

9. Winds
Winds are caused by uneven heating of the Earth’s surface by energy from the sun
Oceans heat slower --- give off heat slower
Winds from the ocean are called ocean winds and cool during the day and warm at night

10. Tools Rain gauge – measures rain fall Hygrometer – measure humidity
Barometer – measures air pressure

11. Weather
What causes floods?
High precipitation
High runoff

12. Hurricanes are over water, formed when air moves to the center and rises.
Tornados form over land

13. Greenhouse Caused by man made pollution Transportation/cars
The pollution causes the heat to be traped and heats the Earth, polar ice will melt, seas will rise.
What can we do??? Plant trees? Stop pollution
