Warm-up 1. What are Earth’s 4 “spheres?” 2. Which spheres does the Biosphere include? 3. What type of force flattens, or takes away geosphere? 4. What does the theory of Plate Tectonics explain? “Representing Earth’s Surface” Chapter 1, Section 3 Determining Location Latitude: • North or South of the “Equator” • degreeso Longitude: • East or West of “Prime Meridian” • degreeso Global Grid Locate any place on Earth. Equator: • Divides Earth in two • “Hemispheres” • N↑ & S↓ Prime Meridian & 180º Meridian • ←W & E→ “Hemis” Locating Places Using the Grid Maps & Mapping • All maps have problems. • too small, too big, or out of place Mercator Projection • Longitude = Parallel • Rectangular • Sailors. Robinson Projection • Accurate distance, size, shape • wrong near edges Conic Projection • Maps of small areas Gnomonic Projection • Shortest distance • Sailors, pilots Topographic Maps Earth’s 3-D surface in 2-D 1. Elevation 2. Distance 3. Direction 4. Slope Contour Line: • Elevation • Every point on line = same elevation Contour Interval: • Distance in elevation between “adjacent” contour lines Contour Lines Close contours = Steep! Far contours = Gentle Geologic Map 1. Type & Age of Rocks 2. Color & Pattern Advanced Technology −Google Earth −“Mapquest” −GPS −Satellite Images −“Remote Sensing” • More accurate & precise analysis of Earth’s physical properties Assignment • Read Chapter 1, Section 3 (pg. 11-17) • Do Section 1.3 Assessment #1-7 (pg. 17)
