Biomes

  1. 1. Antonio Martín
  2. 2. What is a Biome? • Biomes are regions of the world with similar climate (weather, temperature) animals and plants.
  3. 3. What is a Climate? • Climate is the type of weather that occurs in an area over a long period of time.
  4. 4. Forest Biomes • Forests are part of two biomes: – Tropical rain forest. – Temperate forest.
  5. 5. Tropical Rain Forests • These forests are very rainy and hot. • Location: near the equator. • Some forests get more than 600 cm (240 in.) of rain each year. • Temperatures range from about 18ºC to 35ºC, which is like a hot summer that lasts all year. • More kinds of plants and animals live in this biome than in any other. • Its huge mass of plants produces much of Earth’s oxygen.
  6. 6. Temperate Forests • Location: eastern North America and other places. • These forests experience four different seasons: summer, winter, fall (UK: autumn) and spring. • Temperatures range from a chilly -30ºC to a warm 30ºC. • Animals: deer, rabbits, skunks, squirrels, and black bears. • Trees: maple, oak, hickory, and beech (lose leaves in the Fall).
  7. 7. Grasslands • Location: central Africa, central U.S, and other regions. • Grasses cover the land in this biome. • There are two types of grasslands: prairies and savannas.
  8. 8. Prairies • Prairies are found in temperate region, such as the central United States. • Temperatures: down to -40ºC in winter, and up to 38ºC in summer. • Animals: dogs, coyotes, hawks, and grouse.
  9. 9. Savannas • They are found in warmer regions, such as central Africa. • Temperatures: remain above 18ºC. • Animals: Elephants, giraffes, lions, and zebras. • It has a dry season in spite of receiving as much as 100cm (40 in.) of rain each year (that’s why there are not many trees).
  10. 10. Desert • It is the driest biome. • Most deserts receive less than 25cm (10 in.) of rain each year. • Plants: Cacti, sagebrush, and other plants. • Animals and plants are adapted to live with little water. • There are a lot of sandy dunes.
  11. 11. Group Presentation II • In groups of three, make a list of what you know about the types of living things that are found in one of the different biomes. (Types of plants, animals, climate, etc.) • Go up to the board and share your knowledge.
