1. Earth Science

2. Water Cycle

3. Clouds

4. Cloud terms  Alto – tall  Strato – spread out  Nimbus – precipitation  Cumulus – heap  Cumulonimbus - column of rain  Cirrus - curl, curly hair

5. Types of weather masses  - cold  -warm  -stationary  -occluded

6. Cold front  Forms when a cold air mass pushes under a warm air mass   warm air rises   thunderheads, cool fair weather

7. Warm Front  Forms when a moist, warm air mass comes up and over a cold air mass   cloudy, little rain/snow & warmer weather

8. Stationary front  Forms when warm and cold air meet and neither air mass has the force to move the other – stand still   clouds, fog, could rain/snow  Usually many days of clouds and precipitation

9. Occluded Fronts  Forms when warm air mass gets stuck between 2 cold air masses. The warm air mass rises as the cool air masses push and meet in the middle   temp drops, heavy winds & precip.

12. Global Warming/Climate Change  Watch the video and take notes on your page about this  Climate Change Climate Change  http://www.epa.gov/climatechange/kids/

13. Global Warming  Increase in temperature/ climate change  Avg increase of 1.4 F every year  Causes:  Effects:  http://news.nationalgeographic.com/news/2004/12/1206_041206_global_ warming.html

14. Lightening  Tiny ice crystals in clouds  electrical currents  - current in cloud vs. + current on ground  zap  Super heated air  explodes  boom

15. Rocks  Why do they rock?  What are they? Mixture of one ore more minerals and sometimes organic matter

16. Observable Properties  How can you classify rocks  Color  *Hardness - Moh’s hardness scale  1 Talc  2 Gypsum  3 Calcite  4 Flourite scratched by penny  5 Apatite scratched by knife  6 Feldspar scratches glass  7 Quartz scratches steel  8 Topaz scratches quartz  9 Corundum  10 Diamond

17.  Streak  Cleavage/fracture  Magnetism  Specific gravity: compare with the density of water

18. Rock Types Igneous Sedimentary Metamorphic

19. Igneous  Classified on where they form
