Unit 17 weather, climate and people

  1. 1. Unit 17 Weather, Climate and People
  2. 2. Objectives • Discuss how weather and climate affect people positively or negatively.
  3. 3. Positive Effects of Weather and Climate on people • Energy • Farming • Tourism
  4. 4. Energy • Man can harness solar energy and wind energy. • Solar panels on the roofs of home will trap solar energy and convert the energy into electricity for heating water. • In some countries, solar energy is used to replace petrol. • Wind is used to turn wind turbines to produce electricity.
  5. 5. Turbine Solar panel
  6. 6. Farming • Climate determines the amount and the type of crops that can be grown. • For example, in tropical climate, farmers are able to grow more than one crop a year as there is high temperature and high rainfall throughout the year.
  7. 7. Tropical fruits
  8. 8. Tourism • Tropical island with hot and sunny such as Maldives attract tourists from countries experiencing winter. • Tourists from warmer countries like to visit Switzerland to ski Swiss Alps.
  9. 9. Maldive Island
  10. 10. Swiss Alps
  11. 11. Negative Effects of Weather and Climate on people • Too much water • Too little water • Extreme heat and cold • Extreme winds
  12. 12. Too much water • Extreme weather like prolonged heavy rain can cause rivers to overflow their banks and cause flood. • Buildings, transportation networks and farmlands are damaged. • Houses may be swept away and lives may be lost.
  13. 13. Floods
  14. 14. Too little water • Droughts occur when there are prolonged and abnormally dry periods of insufficient rainfall. • Rivers, reservoirs and lakes may dry up. • Crop failure may lead to famines. • Eg: Sudan, Ethiopia and Somalia.
  15. 15. Drought
  16. 16. Extreme heat and cold • Heat waves that occur in summer may cause bushfires and kill lives and destroy farmlands. • Cold waves are caused when frigid polar winds blow into a certain regions. Temperature fall drastically to below 0◦C. People who are not properly protected may be vulnerable to pneumonia, bronchitis and frost bite.
  17. 17. Heat waves
  18. 18. Extreme winds • Severe storms such as hurricanes and tornadoes generate strong winds that cause deaths, injuries, crop and property destruction. • Tornadoes and Hurricanes occur every summer in USA. • Continuous heavy rainfall result in severe flooding that cause greater damage.
  19. 19. Tornadoes
  20. 20. Hurricanes
  21. 21. Questions to ponder… • Why do you think there is an increase in hurricanes and tornadoes? • What is the main difference between a hurricane and a tornado?
