Tropical Rainforest

  1. 1. Tropical Rainforest: An Introduction
  2. 2. Description of a rainforest <ul><li>Densely wooded </li></ul><ul><li>Location: Warm, tropical and wet climate </li></ul><ul><li>Soil: Nutrient Poor-hard to grow crops </li></ul><ul><li>Rainfall: Average 80 inches/year </li></ul><ul><li>(sometimes as high as 400 inches/yr) </li></ul>
  3. 3. Difference between tropical rain forest & temperate rain forest <ul><li>1. Tropical rainforest: Located in the tropics; very warm climate and LOTS of rain </li></ul><ul><li>2. Temperate rainforest: More seasonal, less rain </li></ul>
  4. 4. Remaining rainforests Dark Green Areas= only remaining rainforest left
  5. 5. Layers of the tropical rainforest * Tall Trees- 150ft tall; branches at the highest level; act like an umbrella * VERY THICK! Less than 2% of sunlight reaches the next layer; animals live here * Trees grow to about 12ft. Home of leopards, snakes, and insects Shrub layer * Grow shorter than 12 ft * No growth, no sunlight & 100% humidity
  6. 6. <ul><li>The Soil: Few nutrients, decomposition occurs quickly. The nutrients are absorbed by the trees </li></ul><ul><li>Buttress Root System: Above ground or very shallow root system </li></ul>
  7. 7. Why is the rainforest so important? <ul><li>Contains 90% of all living “things” </li></ul><ul><li>70% of all plants have cancer fighting properties </li></ul><ul><li>Large amount of oxygen produced in the rainforest </li></ul>
  8. 8. How & why the rainforests are being destroyed <ul><li>Slash and Burn: </li></ul><ul><li>Cutting down the forest for farms, roads, & other development. The trees are then burned </li></ul>
  9. 9. <ul><li>Bio Diversity: Many types of animals, insects, & plant life </li></ul><ul><li>Deforestation: Cutting down large areas of forest </li></ul>
