Presentation Transcript

  1. NS3310 - Physical Science Studies Landscapes (Topographic Maps)

  2. Stratigraphy • Law of Superposition • Law of Original Horizontality • Law of Continuity • Law of Cross-Cutting Relationships

  3. Unconformities • Parallel Unconformity • Erosional Unconformity (Disconformity) • Angular Unconformity

  4. Block Diagrams • Block Diagrams show the geologic history of an area. • The laws of stratigraphy can be used to interpret the sequence of events in the region.

  5. Landscapes • Tectonic Landscapes • Volcanic Landscapes • Faults and Folds • Plateaus • Glacial Landscapes • Alpine and Continental • Humid Landscapes • Siliciclastic Coastlines • Meandering Rivers • Estuaries, Bays and Barrier Islands • Arid Landscapes • Mesas and Buttes • Alluvial Fans and Playa Lakes

  6. Location on a Map • Latitude and Longitude • Poles • Equator • Time Zones

  7. Scale • Verbal Scale • Graphic Scale • Fractional Scale

  8. Showing Relief on a Map • Contour Lines • Elevation • Gradients • Relief

  9. Topographic Profiles • Vertical exaggeration = vertical grid scale / map scale

  10. Topographic Maps

  11. Geologic Maps

  12. Key Concepts • Latitude and Longitude are used to specify a location on the earth’s surface. • Topographic Maps show landscape features as well as roads and landmarks. • Topographic Maps use contour lines to indicate elevation and relief. • Geologic Maps show the rock type exposed on the earth’s surface.
