background image Physical Geography 1114 Week 1: Chapter 1 - Essentials of Geography  Geography: “to write about Earth” - is the science that studies the relationships among:  •  Geographic areas  •  Natural systems (weather, water, etc.)  •  Society  •  Cultural activities  •  The interdependence of all the above through space. (on Earth)  5 Themes of Geography  1.  Location - identifies a specific address or absolute and relative position on Earth.  2.  Place - the characteristics - both human and physical-of a location.  3.  Region - uniform physical or human characteristics.  4.  Movement - Communication, migration, and diffusion across Earth’s surface represent  movement in our interdependent world.  5.  Human-Earth relationships - the way we, as humans, affect the Earth.  Scientific Method  1.  Observation – observe nature, ask questions, collect preliminary data.  2.  Form Hypothesis – Put forth a logical explanation.  3.  Experiment and measure – Conduct experiments to test hypothesis (“Hypothesis testing”)  4.  Results  5.  Peer Review – communicate findings for evaluation by other scientists.  6.  Develop a scientific theory – hypothesis survives repeated testing without being rejected.  Basic Map Elements  •  ALL maps must contain:  o  North Arrow 
background image o  Scale Bar  o  Title  o  Legend  Map scale - the ratio of the size of a map to the size of that area on the ground.  •  Three ways of showing map scale:  Representative fraction - most common is 1: 24,000  Written scale  Graphic scale  Map Projections - attempt to portray the surface of the earth or a portion of the earth on a flat  surface.  •  Impossible!  •  Some distortions always result from this process.  •  All projections have distortions in one of four basic properties:  Shape  Relative area  Distance  Direction  •  Cartographers can control or reduce one or more basic property distortion.  Properties of Map Projections  •  Scale - relationship between a distance portrayed on a map and the same distance on the  Earth.  •  Area - when a map portrays areas over the entire map so that all mapped areas have the  same proportional relationship to the areas on the Earth that they represent.  •  Distance - a map is from the center of the projection to any other place on the map.
