2 ClimateAverage weather conditions of an area over a long period of timeMainly precipitation and temperatures3 Climate Zones on Earth1. Tropical2. Temperate3. Polar
3 Natural Factors that affect climate 1. Latitude (distance from the equator)
4 Natural Factors that affect climate 2. Prevailing winds in the Atmosphere
5 Natural Factors that affect climate 3. Mountain formations(topography)
6 Natural Factors that affect climate 4. Large Water Bodies
7 Natural Factors that affect climate 5. Ocean Currents
8 BiomesRegion of similar climateSimilar plant/animal life
9 Tropical Zone ~ The region that surrounds the equator ~ Receive the most solar radiation~Temperatures are usually hot, except at high elevations~ Includes :Tropical Rain ForestsTropical SavannasTropical Deserts
10 Temperate Zones~ The climate zone between the Tropics and the polar zone~ Receive less solar energy than latitudes in the Tropics~ Temperatures tend to be lower than the Tropics~Includes:Temperate ForestTemperate GrasslandChaparralTemperate Desert
11 Polar Zone ~The North or South Pole and its surrounding area ~Has the coldest average temperatures (below freezing all winter and cool summers)~Includes:TundraTaiga
12 Marine Biomes~Shaped by abiotic factors – temperature, water depth, amount of sunlight that passes into the water. The largest of all biomes. Water covers ¾ of the Earth~Organisms of all sizes can be found~IncludesFreshwaterSaltwater
13 Freshwater and Saltwater Freshwater includes: ponds, lakes, streams, rivers, and wetlandsSaltwater includes: oceans, coral reefs, estuaries
14 Rain Forest Biome (Tropical) Temperature: Warm and wet; seasons do not varyPrecipitation: Lots of rain (more than 200cm/yr)Soil: Thin and Nutrient PoorPlants/Animals: greatest number of any biome; most diverse place on Earth
15 Savanna (Tropical) Temperature: usually very warm Precipitation: dry season 4-8 months followed by short periods of rainSoil: nutrient poor (grass fires during the dry season leave the soils nutrient enriched)Plants/Animals: tall grasses, trees, and thorny shrubs, lions, crocodiles and elephantsAfrica and South America
16 Tropical Desert Biome (Tropical) Temperature: extremely hot usually with cooler nightsPrecipitation: driest place on Earth.Soil: poor in organic matter which is needed for plant growth.Plants/Animals: only those that have adapted to live with little water: snakes, rats, plants that are able to store water.
17 Temperate Forest (Temperate) Temperature: Cool winters; warm summers/mildPrecipitation: regular and plenty of itSoil: very fertile and organically rich1. Deciduous forest (temperate)~Trees lose leaves~Lots of animal and plant types2. Coniferous forest (temperate)~Tall pine trees, small plants~Lots of animals
18 Temperate Grassland (Temperate) Temperatures vary: Winters are cold; Summers are hotPrecipitation: seasonal; some regions receive too little rainfall for trees to growSoil: most fertile soils of all biomes
20 Temperate Desert (temperate) Temperature: Tend to be cold deserts (light snow during the winter)Precipitation: less than 25cm yearlySoil: poor in organic matterThese deserts can be hot in the daytime, but they are often VERY cold at night
21 Tundra Biome (Polar) Temperatures are very cold Short summers with almost 24 hrs of lightLong cold winters with almost 24hrs of nightPrecipitation is very limitedSoil is frozen most of the year with only the top layer thawing in the summer
22 Taiga (Polar) Temp: Long cold winters; Short summers Precipitation is moderateSoil: acidic which most plants cannot grow in. Majority of the trees are evergreen.
