Earth moves around the Sun in an elliptical orbit
-Aphelion = Earth is at its furthest point from the sun
-Perihelion = Earth is at its closet point to the sun
-Varies between 91 and 96 million miles.
Circle of illumination = The line on the earth's surface dividing light from darkness
Question? Does the sun rise? Explain.
Planet earth- 71% water 29% land
Does that cause much of a role in the weather on earth?
Does it make a difference if the water is cold or warm?
Tropic of Cancer 23.5 degrees N
Tropic of Capricorn 23.5 degrees S
Question? What does the Tropic's location have to do with the Arctic and Antarctic
December 21== Southern Hemispheres summer
Specific heat = amount of heat energy held at a specific temp. by a substance
Highest specific heat of all liquids except ammonia = H20
-Shallow H20 heats up faster than deep H20
Question? Is that statement about shallow water always true? Explain.
Greenhouse effect = Short wave radiation can go through atmosphere/glass but
reflecting Long waves cannot pass through. Why does that phenomenon occur and what
are the implications to our weather.
Question? What does it have to do with Woburn, Mass being the former carnation
growing center of America?
LCL = That is the altitude at which clouds form.
Question? What is the difference between condensation and precipitation?
90% of all Earth's weather happens in the Troposphere
Hot air rises => lighter => holds more moisture
Cold air sinks => dense => holds less moisture
100% RH (relative humidity) = precipitation
This occurs at dew point temperature and altitude.
Question? What has occurred that causes snow?
