  1. 1. Group member
  2. 2. FACT!!! <ul><li>Dry season this year would be much hotter than a decade ago. </li></ul>
  3. 3. LEARNING ISSUES <ul><li>How long drought season could be? </li></ul><ul><li>What factor increasing the temperature? </li></ul><ul><li>What is the effects to the plants if draught season continues? </li></ul><ul><li>What cause the land in the village to dry? </li></ul>
  4. 4. IDEAS <ul><li>Due to human activities which lead to global warming. </li></ul><ul><li>Climate changes during that year. </li></ul><ul><li>Green house effect. </li></ul><ul><li>They lives in temperate region. </li></ul>
  5. 5. GLOBAL WARMING <ul><li>Global warming is when the earth heats up (the temperature rises). </li></ul><ul><li>  This hurts many people, animals, and plants.  Many cannot take the change, so they die. </li></ul>
  6. 7. <ul><li>  It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.  </li></ul>
  7. 8. EFFECT OF GLOBAL WARMING <ul><li>  Global warming makes the sea rise, and when the sea rises, the water covers many low land islands.  This is a big problem for many of the plants, animals, and people on islands. </li></ul><ul><li>Killing and harming algae when sea water temperature rise. (algae as food source). </li></ul><ul><li>Causing acid rain. </li></ul>
  8. 9. STOP GLOBAL WARMING!!!!!
  9. 10. Greenhouse effect
  10. 12. <ul><li>Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth's surface, land, water, and biosphere absorb the sunlight’s energy. Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up. </li></ul>
  11. 13. What factor increasing the temperature ? <ul><li>The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. </li></ul><ul><li>The glass panels of the greenhouse let in light but keep heat from escaping </li></ul><ul><li>if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals. </li></ul>
  12. 14. TEMPERATE REGION <ul><li>Temperate climate are those without extreme of temperature and precipitation (rain and snow). Such region include western europe, in particular the UK and western north America at latitute between 40 and 60 degrees north . </li></ul>
  13. 15. What season do drought occur? Droughts can occur at any time of year, although technically speaking, a drought is measured over a long period of time. Some areas that receive their rainfall in winter may experience drought in the following summer if falls are below average, while it would be opposite for those who experience main rainfalls in summer.
  14. 16. <ul><li>Most droughts tend to occur during summer, as the weather is hot and water is quickly evaporated. </li></ul><ul><li>Droughts can last for years in most extreme cases. These types of droughts effect outback properties and can devastate crops and livestock. However, many crops are effected. If a farmer has lost his crop due to drought then he will get no money to pay for the next seasonal crop . </li></ul>
  15. 17. What causes drought? Caused by lack of rain over a long period of time . If rain does occur it usually isn't enough for the ground to absorb before it is evaporated again.
  16. 18. Where do droughts occur ?? <ul><li>Droughts usually occur in hot dry areas of land. In most cases the area is dry because there is very minimal rainfall. The rain that does fall will be quickly absorbed into the ground or blown away by the dry air flow that moves along the ground. Therefore the land is very dry and not many things can live there. </li></ul>
