Clouds

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

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

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

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

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

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.

Global Warming/Climate Change  Watch the video and take notes on your page about this  Climate Change Climate Change 

Global Warming  Increase in temperature/ climate change  Avg increase of 1.4 F every year  Causes:  Effects:  warming.html

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

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

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
