3 KEY WORDS Precipitation Rain, snow, or hail, all of which are formed by condensation of moisture in the atmosphere and fall to the groundClimateThe typical weather pattern in a place over a long period, including the precipitation, temperature, and seasonal patternsBiomea stable community of plants and animals in a particular geographic area with a distinct climateAbiotic: non living factors in an environmentBiotic: living factors in an environment
4 Land BiomesThe climate of the region depends partly on where on Earth the region is.*remember: Climate includes a region’s precipitation, temperature, and seasonal patterns.When climates stay the same over long periods of time, the living parts of an ecosystem tend to become stable.Therefore, Biomes are stable communities of plants and animals in certain locations that have distinct climates.There are SIX different land biomes: starting at the poles and moving toward the equator, biomes occur in the following order:
6 TundraLocated in the far Northern parts of the world at the tops of very high mountainsMost of the ground remains frozen for several inches making it impossible for deep-rooted plants to growA lot of lichen and moss on the rocksLong winters and short summersIn the winter it is dark all of the time, while in the summer the sun barley setsPrecipitation is roughly 10 inches annuallyIn North America the tundra is limited to northern Alaska and Canada, and to the higher peaks of the Rocky Mountains.
8 Taiga Located South of the northern tundra Taiga is the Russian word for forest and is the largest biome in the world.The average temperature is below freezing for six months out of the year. The winter temperature ranges from -65 to 30° F. Temperatures in the summer get as low as 20° F. The high in summer can be 70° F.Precipitation is roughly 8-24 inches annually.The taiga in North America stretches from Alaska across central Canada to the Atlantic Ocean.
10 Temperate Deciduous Forest "Deciduous" means to fall off, or shed, seasonally.Four distinct seasons each yearApproximately inches of rainfall annuallySoil is very rich in nutrientsMany types of plants grow thereTherefore, many types of consumers live in these forestsIn North America occur mostly from southeastern Canada through the mountains of northern Georgia and west to the Mississippi River.
12 Savanna in the Samburu Game Preserve, Kenya GrasslandSavanna in the Samburu Game Preserve, KenyaLocated in the interiors of continentsRainfall is irregular: approximately 4-16 inches annuallyWind blows constantlyMost of the world’s wheat, corn, and soybeans are grown hereNorth American grasslands stretch from central Canada through Texas and into Mexico.
14 DesertDeserts can be either hot such as the Australian Desert or cold such as the Gobi Desert.Very little rainfall from year-to-year: approximately 4 inches annuallySome have warm to hot temperatures all year roundNo trees and a few dried up bushesOthers have a wider range of temperature from winter to summerMuch warmer during the day than it is at nightIn North America, desert reach from the interior of southwestern Canada through northern Mexico
16 Tropical Rain Forest Nearest to the equator **NO “normal” season**because it is the same temperature all year longThere are two seasons-rainy and dry (which just means there is less rain than in the rainy season)Approximately 100 inches of rainfall annuallyLots of birds, some mammals and a lot of insects.In North America, Tropical Rain Forest occur from southern Mexico through Panama, on many of the islands in the Caribbean and in Hawaii.
17 ConclusionThe Six Major Land Biomes are: The Tundra, Taiga, Deciduous Forest, Tropical Rainforest, Grassland, and Desert.The climate of each Biome is unlike the other biomesClimate is affected by the temperature, precipitation, and seasonal patternsThe coldest climate zones are near the polesThe warmest climate zones are near the equatorPlants and animals will demonstrate their adaptation to the climate of a particular biome.
