1 KEY CONCEPT Climate is a key abiotic factor that affects the biosphere.
2 Climate is the prevailing weather of a region. Climate is the long-term pattern of weather conditions.average temperatureprecipitationrelative humidityKey factors shape an area’s climate.temperaturesunlightwaterwind
3 A microclimate is the climate of a small specific place within a larger area.
4 Earth has three main climate zones. The three main zones are the polar, tropical, and temperate climates.polar climate: the far northern and southern regions of Earthtropical zone: surrounds the equatortemperate zone: the wide area in between the polar and tropical zones
5 The angle of the Sun’s rays help determine an area’s climate. temperatepolartropical90 N
6 Earth’s tilt on its axis plays a role in seasonal change. Solar heating causes movements in both water and air.windocean currentsEarth’s rotation also has effects on the winds and currents
7 Landmasses shape inland climates. larger changes in temperaturesless precipitationOceans shape coastal climates.smaller changes in temperatureshigher humiditymore precipitation
8 Mountains have an effect on climate. Precipitation occurs on the side of the mountain facing the wind.On the downwind side, drier and cooler air produce a rain shadow.A rain shadow is an area of decreased precipitation.western slopeeastern slope
9 Many organisms survive in a specific climate due to their adaptations.
