### Unit 1 Maps

• 1. UNIT 1 - MAPS 1- How is the Earth represented? 2- What types of maps are there? 3- How do we locate places on maps? 4- How do we represent scale on a map?
• 2. Glossary It is a drawing of a particular area such as a city, a country, or a continent, showing its main features. Map It is one of the four principal compass points: north, south, east, and west. Cardinal point It is the information given with the map to explain the meaning of the symbols and colours drawn on it.Map key It refers to the relationship between distance on a map and the corresponding distance on the ground. Scale map
• 3. Glossary Meridian It is an imaginary line between the North Pole and the South Pole, drawn to help to locate any place on the Earth. Parallel It is an imaginary line drawn on the Earth´s surface which is perpendicular to the meridians. The most important parallel is the Equator. Latitude It is a geographical coordinate; it indicates thenorth/south position of a point on the Earth´s surface. It ranges from 0 degrees at the Equator to 90º at the Pole (North/South) Longitude It is a geographical coordinate; it indicates the east/west position of a point on the Earth´s surface. It ranges from 0 degrees at the Prime Meridian to 180º at the Antimeridian.
• 4. 1- How is the Earth represented? The Earth is spherical but slightly flattened at the poles geoid How do we represent the Earth? Globe Maps How is the Earth in shape? Three-dimensional Not detailed information Easy to carry Two dimensional Practical information
• 5. 1- How is the Earth represented? What are the cardinals points? The elements we use to establish direction; the principal are north, south, east and west. Do you know any other elements that can help us to establish direction? Nature The Sun North Star Instruments Compass: always points north Always indicates north Rises in the east; sets in the west.
• 6. 1- How is the Earth represented? How is the Earth in shape? How do we represent the Earth? What are the cardinals points? Do you know any other elements that can help us to establish direction? Think: Nowadays we have modern instruments like GPS or digital maps that allow us to establish direction easily; Why do you think it´s important to learn the traditional methods to orient yourself or navigate?
• 7. 2- What types of maps are there? Types of maps Physical Information on relief and rivers One specific physical map is the topographic map (It also details names, roads, buildings…) Thematic Information on one particular subject Political Information on political organisation: frontiers, capital cities..
• 8. 2- What types of maps are there? Which are the basic elements of a map?
• 9. 2- What types of maps are there?Which elements are missing?
• 10. 2- What types of maps are there?Which elements are missing?
• 11. 2- What types of maps are there? Name and describe the main types of maps Which are the basic elements of a map? Describe their function. Activities 1,2 and 3 on page 9.
• 12. 3- How do we locate places on maps? Meridians and parallels It is a grid of imaginary lines that enable us to identify the exact location of places on Earth. Meridians Parallels Semicircles which go from one Pole to the other. Prime meridian (0º) is the reference for other meridians. Circles which are perpendicular to the meridians The Equator is the most important; divides the Earth in two hemispheres. Other parallels Artic Circle Tropic of Cancer Tropic of Capricorn Antarctic Circle https://www.youtube.com/watch?v=ChBhKPh B4VE&list=PLc- jghROQMcLrGQCkLn4Cr9avGfkJ-_IM&index=1
• 14. Arctic Circle Prime meridian Equator Tropic of Cancer Tropic of Capricorn Antarctic Circle
• 15. Western Hemisphere Prime meridian Eastern Hemisphere The prime meridian divides the Earth in two halves: the western and the eastern hemisphere.
• 16. Northern hemisphere Equator Southern hemisphere The Equator divides the Earth in two halves: the northern and the southern hemisphere.
• 17. 3- How do we locate places on maps? Define parallels and meridians. Which one is the main meridian? Which are the main parallels? What is the Equator? Explain the differences between the parallels and the meridians? Parallels and meridians
• 18. 3- How do we locate places on maps? Geographical coordinates It is a system that enables every location on Earth to be specificied. The geographical coordinates are the latitude and the longitude. Latitude Measured by using the parallels From 0º to 90º; north or south All locations on the same parallel have the same latitude. Distance to Equator measured in degrees. Longitude Distance to Prime Meridian measured in degrees. Measured by using the meridians All locations on the same meridian have the same longitude. From 0º to 180º; east or west
• 19. 3- How do we locate places on maps? Latitude and longitude Explain the difference between latitude and longitude Activity 1 on page 11. https://www.youtube.com/watch?v=T1E0I4eL KNI https://www.geovista.psu.edu/grants/ MapStatsKids/MSK_portal/concepts_l atlg.html
• 20. 3- How do we locate places on maps? Latitude and longitude Latitude Longitude London Rome Quito Kinshasa 21º S 38º W 38º N 140º E 32º S 150º E 52º N 0º Río de Janeiro 42º N 13º E 0º 75º W Tokio 3º S 17º E Sydney
• 21. 4- How do we represent scale on a map Scale Map element that indicates the difference between the size of something in the real world and its size on a map. Map scale types https://kidsgeo.com/geography-for-kids/map- scale-types/ The scale of a map uses a representative fraction to describe the ratio between the map and the real world. Numeric scale (fractional method)
• 22. 4- How do we represent scale on a map? Graphic scale (Graphic method) A line divided into equal segements. The number indicates the size which each segment represents.
