Biomes! Biomes! Presentation Transcript

  • BIOMES Chapter 21 Page 728
  • Biomes of the Earth
  • ForestsThere are three types of forests…1.) Temperate Deciduous Forests2.) Tropical Rain Forests3.) Taiga (Coniferous Forests/Boreal Forests)
  • TemperateDeciduous Forest
  • Temperate Deciduous Forest• Deciduous means “to fall off” – the trees in this region have leaves that fall off.• We live in a temperate forest!• Rainfall – 75 – 125cm• Temp.- Summer – 28C, 82F Winter– 6C, 43F
  • Temperate Deciduous Forest’s are typically found in the northern hemisphere.Click to the next slide to see plants andanimals commonly found in this biome
  • Tropical Rain Forest
  • Tropical Rain Forest• More species live here than any other biome• Canopy – treetops in the rainforest. Most animals live there• Very little light reaches the ground b/c of the canopy• This is the wettest and warmest biome• Rainfall – up to 400cm• Temp.- Daytime– 34C, 93F Nighttime– 20C, 68F
  • The world’s rainforest’s are found in tropical locations near the equator.Click to the next slide to see plants andanimals commonly found in this biome
  • Taiga
  • Taiga• This biome has long cold winters• Have evergreen trees – trees that stay green all year long.• Conifers are trees that produce seeds in cones and have needle-like leaves (pine trees)• Animals in this biome often hibernate or migrate• This is the largest biome• AKA: coniferous forest and boreal forest
  • Taiga •Rainfall – 35 - 75cm •Temp.- Summer – 14C, 57F - Winter – -10C, 14F
  • The taiga is only found in the northernhemisphere and it’s the largest biome Click to the next slide to see plants and animals commonly found in this biome
  • Grasslands-Grasses are the main vegetation.-There biomes are typically found between forests anddeserts.-These biomes exist on every continent.-They are also known as plains, prairies, savannas, andsteppes.
  • Temperate Grassland
  • Temperate Grasslands•This biome has mixed grasses withvarious plants and a few trees•Rainfall – 25-75cm•Temp.- Summer – 30C, 86F Winter – 0C, 32F
  • Savanna
  • Savanna• Tropical grassland with scattered clumps of trees.• It has a rainy season and a dry season.• The majority of the world’s savannas are in Africa.• Rainfall – 150cm• Temp.- Rainy Season – 16C, 61F Dry Season – 34C, 93F
  • The Earth’s GrasslandsClick to the next slide to see plants and animalscommonly found in this biome
  • Desert
  • Desert• Hot and dry with a variety of plants and animals.• Animals are most active at night (nocturnal)• This is the biome with the least rainfall• Rainfall – less than 25cm• Temp.- Summer – 38C, 100F Winter – 7C, 45F
  • The Earth’s DesertsClick to the next slide to see plants and animals commonlyfound in this biome
  • Tundra
  • Found in the far north and on the tops ofmountains.No trees are found in the tundra.It is the coldest biomeThere are two types of tundra: artic andalpine Tundra
  • Arctic Tundra• Has permafrost which stays frozen year round• Water is available and the surface is wet and soggy• Lakes and ponds are plentiful
  • Alpine Tundra• Lots of sunshine and precipitation in the form of snow• Located above the tree line of tall mountains
  • The tundra is located above thetaiga in the northern hemisphere Click to the next slide to see plants and animals commonly found in this biome
