Name the Global zones from North to South:
At how many degrees are the Tropic of Cancer, the Mediterrenean and the Arctic Circle located?
Artic Circle: 66°n (between Temperate and Subpolar zone)
Mediterrenean: 40°n (between Temperate and Subtropical zone)
Tropic of Cancer: 23°n (between Tropical and Subtropical zone)
What is climate?
Climate is the average weather over a long period of time. e.g. Monsoon climate (raining season=summer)
What is weather?
Weather is the day-to-day condition of the atmosphere (weekly changing) in terms of temperature, rainfall, sunshine and wind.
What are the climatic factors?
What factors affect temperature?
Distance from the equator (latitude)
Distance from the sea
Why does the latitude (=distance from the Equator) affect the temperature?
Because places that are closer to the Equator are warmer than places near to the poles.
Why are places closer to the Equator warmer?
the curvature of the Earth: at the equator the heat is concentrated upon a small area, but due to the great curvature near the poles there is a larger area to heat up there
the angle of the sun in the sky: as the sun's rays pass through the atmosphere at a more direct angle (and therefore more quickly) at the Equator, less heat is lost
the layer of atmosphere that surrounds the Earth: the amtosphere contains dust, smoke and other solid particles that absorb heat
