  1. The Big Idea Geographyis used to interpret the past, understand the present, and plan for the future.

  2. 5 Themes of Geography • Location • Place • Human-Environment Interaction • Movement • Regions

  3. 5 Themes of Geography • Geographers use five themes to describe places and people • Location: • Position of a place on the Earth’s surface • Absolute Location– the exact spot where a city or mountain is found • Relative Location– describes where that city or mountain is in relation to the features around it

  4. 5 Themes of Geography • Place: • Describes the characteristics of a location that make it unique, or different • Described by physical features, such as landforms, plants, animals, and weather patterns • Described by the people who live there, such as what languages they speak

  5. 5 Themes of Geography • Human-Environment Interaction: • Describes how people affect their environment, and how the environment affects them • People affect the environment by using or changing it to meet their needs • Temperature and natural disasters influence how people live

  6. 5 Themes of Geography • Movement: Explains how and why people, ideas, and goods move from place to place

  7. 5 Themes of Geography • Regions: • The areas of Earth’s surface that have several common characteristics (ex: land, natural resources, or population)

  8. The Big Idea Geographers use many different tools to help them study and analyze Earth’s people and places.

  9. Types of Geography • Physical Geography– look at Earth’s land areas, bodies of water, plant life, and other physical features • Study natural resources • The way people use resources • Make decisions about managing different types of resources

  10. Types of Geography • Human Geography– look at people’s religions, languages, and ways of life • Study specific locations, entire countries, or continents • Compare and contrast different places • Help plan cities and international business

  11. Map Systems • Maps can provide geographers with different types of information about a place • Satellites: • Provide digital images and pictures to create maps • Measures changing temperatures and air/land pollution • Make upGlobal Positioning System (GPS)

  12. Map Systems • Geographic Information Systems (GIS) – gathers, stores, and analyzes information • Displays maps, types of vegetation, types of soil, and/or water quality

  13. Careers in Geography • Geographers help decide how land and resources might be used • Analyze population trends • Help companies decide where to locate new buildings • Provide information about places and cultures • Teach in high school and colleges

  14. The Solar System • My Very Exhausted Mother Just Served Us Nothing • Mercury • Venus • Earth • Mars • Jupiter • Saturn • Uranus • Neptune Mercury orbits the sun in 88 days but Neptune takes 165 YEARS!

  15. Earth’s Movement • One revolution – 365 ¼ Days (One year) • Leap Year– Every 4 years to make up for the extra day • Earth rotates fully on its axis every 24 hours (one day) • We do not feel Earth moving because the atmosphere moves with it

  16. Sun and Seasons • Earth is tilted 23 ½ degrees creating seasons as it orbitsthe sun • Direct rays = warmth of summer • Indirect rays = cold winter

  17. Solstices and Equinoxes • June 21 – North Pole tilts toward the sun – Summer Solstice • December 22 – North Pole tilts away from the sun – Winter Solstice • Equinoxes – midway between solstices when day and night are identical • March 21 • September 23
