Our World

Summary for 2/6/06

NOTES= 1.Global Climates

-Weather: Short-term, day-to- day expression of atmosphere processes

-Climate: long-term, average conditions usually at least 30 years of daily weather data(temps. + precipitation).

-Climate Region: boundaries drawn around areas with similar average climate conditions. Helps us make inference about human activities and settlement.

-Climograph: Provides "Average Rainfall Figure". Provide average high and low temp. and precipitation for every month in an entire year. Includes Average high temp., Average low temp., and Average precipitation.

GLOBAL WARMING

1.Human Activities are connected with economic development and industrilization affect the world's climate.

2.Anthropogenic: Rising sea-levels as polar ice-cap melts.

Causes of Global Warming
-Natural Greenhouse effects make the Earth warm enough to support life.
-Beginning with Industrial Revolution inEurope and North America, greenhouse gases have increased dramatically mostly from burning fossil fuels.
-Co2, CFCs, CH4, N2O= major greenhouse gases.
Effects
-Average glabal temp. will increase 2 degress to 4 degress.
-Major shift in agricultural areas
-Wheat Belt=warmer and drier until lower grain yield.
Southern Regions of U.S. and Europe=warmer and drier.
We watched a movie about volcanic activity in Iceland, which was semi-interesting. The fact that the Earth is almost like a breathing, living creature is a great analogy. The fact that islands can just sprout out of the sea or dissapear in the blink of an eye is pretty interesting. Anyway, the rest of the movie went on to explain such things as the tectonic plates and uses a volcano in Iceland as the main story focus about the Earth.

Went to the lab and worked on GIS after a few notes
