## 6th Grade Geography-Ch. 1 Sec. 2Presentation Transcript

• Ch. 1 Sec. 2The Geographers Tools
• globe round model of Earth
• Problem withglobes... • not portable • cant show enough detail
• Problem withmaps... Earth-round • causesmaps-flat distortion
• distortion change in theaccuracy of shape & distances
• projection method of putting a map of the Earth onto a flat piece of paper
• types of mapsMercator Peters interrupted Robinsonsprojection projection projection projection equal accurateconformal accurate size & map area map size & shape of most land shape of shows & oceans most land shows correct & oceans correct sizesshapes but gaps make of land it hard to some not true masses but distortionsdistances & altered figure shapes distances in edges sizes
• Mercator projection
• Peters projection
• interrupted projection
• Robinsons projection
• parts of a map/projection cardinal scale key/legend directionsnorth, south, explains size symbols west, eastcompass rose
• Teacher and the Rockbots How To Read A Map - Song Sample Im lost. What should I do?http://www.youtube.com/watch?v=gbFIhmTd3iYYou need a map. I need a clue. Flower shape - easy to see, Letters N, W, S and E. Why does this help and tell me now what does it mean? Its a COMPASS ROSE. The compass rose shows North, South, East and West. North and South - well now I know, East and West - which way they go. What do you call these four main directions? The CARDINAL DIRECTIONS. Intermediate directions would be northeast, southeast and so on. How far is it from here to there? Can we measure distance to anywhere? The map size is smaller than the real world. Look for the SCALE. The scale is like a little ruler that helps you measure distances between places. A little lost. Im getting clues. From a map. That I got from you. Dots, triangles, colors and many lines; What do all these things define? I see a tiny airplane and what is this star? These are SYMBOLS. An airplane shows the airport; a star is a Capital city. How did you know what the symbols are When youre driving around like in a car? Can you find it on the map and where will it be? Use the MAP KEY. The map key tells you what the symbols mean. This map doesnt show the entire place. I know that its part of a bigger space. Could it be from England, Iraq or Mexico? Look for the INSET. The inset is a small map thats a more detailed view of part of the main map. I was lost. But I learned something new How to read a map. And I thank you
• Guess the Covered Word
• method of putting amap of theEarth onto projectiona flat piece of paper
• north,south, cardinalwest, directions east
• roundmodel of globe Earth
• map that shows correct Mercatorshapes but not true projectiondistances & sizes
• change in the accuracy distortionof shape &distances
• part of amap that key explainssymbols
• part of a map that scaleshows size
• map that showsaccurate size &shape of most Robinsonsland & oceans with some projection distortions at the edges
• map that shows accurate size & shape of most interrupted land & oceans but gaps make projectionit hard to figure distances
• Problem • not portable with • cant showglobes... enough detail
• • Since the Earth isProblem round and with maps aremaps... flat, it causes distortion.
• GREAT JOB!
