    1. World Geography

    2. Chapter 1 Sect.1 Geography is…..

    3. Regions A REGION is an area with one or more common features that make it different from surrounding areas Geographers like to organize big parts of the world into smaller parts (REGIONS) to gain a better understanding of this complex planet we live on

    4. Regions

    5. Regions

    6. Chapter 1 Sect.1

    7. The Six Elements 1.LOCATION: the world in spatial terms ie: latitude and longitude/maps

    8. The Six elements

    9. The Six elements 5. ENVIRONMENT & SOCIETY: How the physical environment shapes cultures and how cultures change the environment. ie: Nomads 6. The Uses of Geography: Geography helps us understand the relationships of people, places, and the environment over time.

    10. What do all maps have in common? DOGSTAILS D (date) O (orientation) G (grid) S (scale) T (title) A (author) I (index) L (legend) S (sources)

    11. Chapter 1 Sect. 2 Organizing the Globe

    12. Chapter 1 Sect. 2

    13. Map Projections

    14. Mercator Projection- distorts the size and shape of large objects, as the scale increases from the Equator to the poles

    15. Peters Projection

    20. A little different look at the World . .which countries might prefer this map?

    21. Chapter 1 Sect. 2

    22. Climate & Weather Weather: The condition of the atmosphere at a given time and place Climate: Weather conditions in a geographic region over a long period of time

    23. Climate & Weather Weather is influenced by these factors: Atmospheric Pressure Global Wind Belts Oceans and Currents Mountains and Elevation

    24. Climate & Weather Weather is influenced by these 4 factors: 1. Atmospheric Pressure (weight of the air around us) 2. Global Wind Belts (the horizontal flow of air)

    25. Climate & Weather Weather is influenced by these factors: 3. Oceans and Currents (oceans moderate temperatures/ currents push the water around)

    26. Climate & Weather Weather is influenced by these factors: 4. Mountains and Elevation (orographic effect/rain shadows)

    27. Orographic effect * Mountains influence climate! But how? *moist air pushes up against mountains *the barrier forces the air to rise *the rising air cools and condensed forming clouds and causes precipitation *therefore, the side of the mountain facing the wind gets moisture (windward side) and the side of the mountain way from the wind (leeward side) is dry and often is a desert. How do you think the orographic effect influences human settlements? Vegetation?

    28. STORMS! STORMS are sudden and violent weather events caused by quick changes in air temperature, pressure and direction Types of storms: Tornados: twisting spirals of air often accompanied by thunderstorms- (middle latitudes- the United States experiences the more tornados than any other country) Lightening strikes and downpours Hurricanes: rotating storms that bring heavy rain and strong winds-(tropics- most powerful of the tropical cyclones)- produces in warmer waters- primarily the Atlantic (Katrina) Typhoons: can produce huge waves, thunderstorms and tornados found in the western Pacific

    29. STORMS! Write your response to the following questions, then share your answers with a partner. How does weather and climate affect human populations? Which factor weather OR climate has more affect on people when deciding where to live? Why? Describe the worst storm you’ve experienced.

    30. Global Warming The increase in the earth’s temperature due an increase in the greenhouse effect, which is how the earth’s atmosphere traps heat. (the atmosphere allows much sunlight to pass through but slows the rate at which the heat escapes) Most scientist believe global warming is cause by human activities (burning coal, natural gas, oil, ect..) Some scientist believe it is a part of a natural cycle. What are some effects of global warming that you are aware of? SEE READING AND QUESTIONS

    31. Climographs -visual comparison of two elements of climate (precipitation and temperature) plotted at monthly intervals throughout the year (See Climographs of Las Vegas and Montreal, Canada)

    32. Climograph Questions 1. Which city has the greatest change in temperature and precipitation over a year’s time? 2. Which has the least? 3. Which city has the most rain? Why do you think that is? 4. Which city has the least rain? Why? 5. What could climographs be used for?

    33. Chapter 3 Sect. 3

    34. Climate and Vegetation Pattern Activity Using your textbook (pages 51-57), the atlas, and your “mind powers”, find climate and vegetation information for the locations listed on your worksheet. Work quickly- you have the hour to complete it. You may work in pairs.
