  1. theBIGidea CHAPTER OUTLINE CHAPTER RESOURCES CHAPTER NEW CHAPTER Climate and Climate Change Climates are long-term weather patterns that may change over time. 18.1 Climate is a long-term weather pattern. 18.2 Earth has a variety of climates. 18.3 Climates can change suddenly or slowly.

  2. SIMULATION Explore the effects of latitude and altitude. 18.1 Climate is a long-term weather pattern. The main factors that influence climate are climate latitude • latitude marine climate continental climate • altitude ocean current • distance from large bodies of water season • ocean currents CHAPTER RESOURCES SECTION OUTLINE

  3. Dry Season Wet Season These photos show the same rice fields in India at different times of the year. 18.1 Climate is a long-term weather pattern. Seasonal changes are also part of climate patterns. climate latitude marine climate continental climate ocean current season CHAPTER RESOURCES SECTION OUTLINE

  4. 18.2 Earth has a variety of climates. • Scientists usually group climates by temperature and precipitation. There are six major climate zones. The six major climate zones of this classification system are: • humid tropical, • Dry • moist mid-latitude with mild winters • moist mid-latitude with severe winters • Polar • Highland climate zone microclimate urban heat island rain shadow CHAPTER RESOURCES SECTION OUTLINE

  5. 18.2 Earth has a variety of climates. Climate zones can be divided into subclimates. Subclimates are divided into smaller areas called microclimates. climate zone microclimate urban heat island rain shadow CHAPTER RESOURCES SECTION OUTLINE

  6. 18.2 Earth has a variety of climates. How can this mountain have snow on it if it’s located in a warm climate? climate zone microclimate urban heat island rain shadow CHAPTER RESOURCES SECTION OUTLINE

  7. 18.2 Earth has a variety of climates. How do oceans affect climate? climate zone microclimate urban heat island rain shadow CHAPTER RESOURCES SECTION OUTLINE

  8. 18.3 Climates can change suddenly or slowly. Natural events, such as eruptions of volcanoes, can change climate. ice age El Niño CHAPTER RESOURCES SECTION OUTLINE

  9. 18.3 Climates can change suddenly or slowly. Slow movement of continents can change climates. ice age El Niño CHAPTER RESOURCES SECTION OUTLINE

  10. 18.3 Climates can change suddenly or slowly. El Niño (ehl NEEN-yoh) is a disturbance of wind patterns and ocean currents in the Pacific Ocean and causes a change in climates. ice age El Niño CHAPTER RESOURCES SECTION OUTLINE

  11. This ice sheet on a mountain in Peru has shrunk 820 meters (2690 ft) in 19 years. 18.3 Climates can change suddenly or slowly. Human activities that release greenhouse gases are also changing climate by causing a global rise in temperature. ice age El Niño CHAPTER RESOURCES SECTION OUTLINE

  12. 18.3 Climates can change suddenly or slowly. • Human activities are changing climate: • By 2100 global temperature will rise 1.4°C – 5.8 °C (2.5 °F – 10.4°F). • Earth hasn’t warmed so rapidly at any time in at least the last 10,000 years. • What ways will global warming impact Earth? • Sea levels will rise as ice melts. • Wildlife will be endangered. • Agriculture will be harmed. • Humans will have more heat related illness and possible deaths. ice age El Niño CHAPTER RESOURCES SECTION OUTLINE
