Warm Up WHAT PARTS OF A MAP CAN YOU NAME? WHAT DO YOU LOOK FOR WHEN YOU SEE A MAP? Introduction to Map Skills IMPORTANT PARTS OF A MAP & GLOBE TO LOOK FOR FIRST 6 Things that should be on EVERY map 1. Title - should be pertaining to the subject of the map. 2. Orientation - Compass Rose should indicate North. 3. Date - What the date is. 4. Author - Who created the map. 5. Legend - What symbols mean on the map. (key) 6. Scale - The size of space on the map TODALS! – THING PARTS OF A MAP THIS IS THE TITLE! ;) Compass Rose shows the “orientation” Map Scale Map Key/Legend ACTIVITY: IDENTIFY THE MAP PARTS 1-4 RAISE YOUR HAND TO ANSWER WHAT TYPES OF MAPS ARE THERE? • Physical • Political • Thematic (Chloropleth and Cartogram) WHAT ARE POLITICAL MAPS? Show features on the earth’s surface that humans created Political Borders – borders decided by Governments (latitude & longitude) Examples? National and State Borders, City Limits, capitals WHAT ARE PHYSICAL MAPS? show types of landforms and bodies of water Physical Borders – countries Separated by a physical feature Ex. Rio Grande River, Ural Mountains WHAT ARE CHLOROPLETHS? Thematic map that uses graded differences in shading or color or the placing of symbols inside defined areas on the map in order to indicate the average values of some property or quantity in those areas Many different kinds. Examples??? Climate Vegetation Natural Resources Population WHAT ARE CARTOGRAMS? A cartogram is a map in which some thematic mapping variable is substituted for land area or distance. The geometry or space of the map is distorted in order to convey the information of this alternate variable. THE GEOGRAPHER’S GRID & LATITUDE/LONGITUDE IMPORTANT LINES ON “GEOGRAPHER’S GRID” Equator - Runs East and West divides Earth into Northern and Southern Hemispheres Prime Meridian Runs North and South Divides Earth into Eastern and Western Hemispheres WHAT IS A HEMISPHERE? One half of the Earth. THE TROPICS Tropic of Cancer – 23.5° North of Equator Sun’s most northern location occurring on June 21st Tropic of Capricorn – 23.5° South of Equator Sun’s most southern location occurring on December 21st THE POLAR CIRCLES Arctic Circle – 66.5° North of the Equator begins the North polar region Antarctic Circle – 66.5° South of the Equator begins South polar regions WHAT IS “LATITUDE AND LONGITUDE”? •It is a grid for finding your location on the Earth. Like “X and Y” from the grid in math class, like a football field, or like the game “Battleship” LATITUDE “FLATITUDE” Run East/ West parallel to Equator Measures North and South Furthest North = 90 degrees North latitude Furthest South = 90 degrees South latitude Important lines of Latitude: 1. Equator 2. Tropic of Cancer 3. Tropic of Capricorn 4. Arctic Circle 5. Antarctic Circle LONGITUDE Run north/ south Measures East and West There are 180 degrees of East longitude and 180 degrees of West longitude Total = 360 degree circle All lines meet at North Pole and South Pole HOW DO YOU USE LATITUDE AND LONGITUDE TO FIND YOUR WAY? 1. Find the right hemispheres (N, S, E, W). 2. Trace latitude and longitude till they meet. 3. FOLLOW THE CURVE! LET’S PRACTICE USING LATITUDE AND LONGITUDE! But first, let’s watch Matt dance!
