  14. So the question is • What can we learn from these different types of images • of the same event • About our planet • Think for 1 minute • Share with your table partner- Be prepared to share with class • IN OTHER WORDS, WHY ARE THESE TECHNIQUES AND TECHNOLOGIES HELPFUL?

  15. Now let’s read a little • Set up 2 Cornell notes pages • Each set of table partners will be assigned a specific section to read and take notes from • Go to assigned section of text • You have 7 minutes to complete your reading and notes with your table partner • You will then switch partners and share the notes from your team- 2 minutes per person • You will switch 2 more times to gather all notes

  16. Topographic Maps • The lines translate three dimensional land features into a two dimensional map • Helpful in hiking and orienteering. They are also used in land-use planning • Rules!!- Contour lines do not cross. They can merge at a vertical cliff. The closer together they are the steeper the terrain. The father apart contour lines are the more gradual the ascent

  17. Topographic Symbols • Index Contour Interval- contour lines that have a number written on them. This number indicates the elevation of all points along the line. • Intermediate Contour intervals- lines have no number on them • Depression-a decline in elevation inside a rise for example a volcanic crater • Supplementary Contour Interval- dotted lines are placed in areas where elevation change is minimal. • Other frequent symbols Blue= water, rivers, lakes Red = land grids and important roads Black= smaller roads, trails, boundaries Green= vegetation

  18. Examples

  19. This is a picture of West Lost Lake • Wouldn’t you love to take a hike and see this place for your self? • It’s just a hop, skip and a jump up into the Flat Tops • I guess we had better find out just how strenuous a hike it is!

  20. Your Turn • With your table partner • Get the following materials: • a topographic map • a half sheet of paper • Ruler and piece of string • a direction sheet and analysis questions.

  21. HOMEWORK • Complete the summary portion in your Cornell Notes on Topographic Maps • Complete the summary portion in your Cornell Notes on LandSat and OSTM/Jason2 • Complete the summary portion in your Cornell Notes on SeaBeam and Geologic Maps • Each summary should be about 3-5 sentences and should fit within the box/space
