1. INTRO TO WORLD GEOGRAPHY: GEOGRAPHY SKILLS Mrs. Minks Social Studies

2. WARM-UP 8.12.14 On an index card, answer the following questions: 1. Name the seven continents. 2. Name the four oceans. 3. What is the highest mountain in the world? 4. What is the largest desert in Africa? 5. What is the longest river in the world? 6. What is the largest river in the United States?

3. FIVE THEMES OF GEOGRAPHY Location – describes where something is Absolute Relative Place – describes physical and human characteristics that make a location unique Regions – areas that share common characteristics Movement – explains how and why people and things move and are connected Human-Environment Interaction – describes relationship between people and their environment

4. WHAT TOOLS DO GEOGRAPHY SKILLS PROVIDE? Methods for us to understand relationships between people, places, and environments Helps in community decisions Where to build a new school How to solve problems of air and water pollution Helps us make personal daily decisions Where to buy a home Where to get a job How to get to the mall Where to go on vacation

5. GLOBES AND MAPS A globe is a scale model of the Earth (3D) A map is a symbolic representation of all or part of the planet (2D) Who makes maps? Cartographers

6. GREAT CIRCLE A Great Circle is an imaginary line that follows the curve of the Earth. Great circle is one of the important differences between a map and a globe.

7. PROJECTIONS To create maps, cartographers project the round Earth onto a flat surface making a map projection. Distance, shape, direction, or size may be distorted by a projection. The purpose of the map usually dictates which projection is used. The three basic categories of map projections are: Planar Projection Cylindrical Projection Conic Projection

8. PLANAR PROJECTION A planar projection shows the Earth centered in such a way that a straight line coming from the center to any other point represents the shortest distance. Also known as an azimuthal projection. It is the most accurate at its center and if often used for maps of the Poles.

9. CYLINDRICAL PROJECTION A cylindrical projection is based on the projection of the globe onto a cylinder. This projection is most accurate near the equator, but shapes and distances are distorted near the poles.

10. CONIC PROJECTION A conic projection comes from placing a cone over part of a globe. Conic projections are best for showing limited east-west areas that are not too far from the equator. For these uses, a conic projection can indicate distances and directions fairly accurately.

11. THE ORANGE ACTIVITY

12. On the back of your warm-up index card describe the problems that arise when the curves of a globe become straight lines on a map.

13. WARM-UP 8.13.14 On an index card answer the following: How many hemispheres are there and what are they? Of latitude and longitude, which one’s lines are parallel?

14. DETERMINING LOCATION Grid system Hemisphere Latitude: circle the Earth parallel to the Equator and measure the distance north or south Longitude: meridians that circle the Earth from Pole to Pole and measure distance east or west of the Prime Meridian at 0° longitude.

15. THE GLOBAL GRID Tokyo, Japan 36°N 140°E

16. HEMISPHERES Northern hemisphere – everything north of Equator Southern hemisphere – everything south of Equator Eastern hemisphere – everything east of Prime Meridian Western hemisphere – everything west of Prime Meridian

17. READING A MAP Title Key Scale bar Compass Rose Cities Capitals Boundary Lines

18. PHYSICAL MAPS Water features Landforms Relief and elevation Boundary lines

19. POLITICAL MAPS Human-made features (boundaries, capitals, cities, roads, etc.) Physical features (mountains, rivers, etc.) Non-subject area – for context

20. THEMATIC MAPS Single idea Particular kind of information Each serve different need (climate, vegetation, etc.)

21. GEOGRAPHIC INFORMATION SYSTEMS GIS designed to accept data from different sources Converts data to digital code, arranges in database GIS can process data and produce maps
