NS Physical Science Studies Landscapes (Topographic Maps)

Stratigraphy Law of Superposition Law of Original Horizontality Law of Continuity Law of Cross-Cutting Relationships

Unconformities Parallel Unconformity Erosional Unconformity (Disconformity) Angular Unconformity

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.

Topographic Maps

Geologic Maps

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.
