8 Module/Unit: Landforms Investigation 5: Bird's-Eye View (Page 2 of 2) Grade Level: Fifth Big Idea: Change takes place when things interact; all things change over time; patterns of interaction and change are useful 1. What are the techniques to create topographical maps? 3. Explain the changes, slow and rapid processes, that affect the earth's surface. to determine how water and earth materials interact to form and change landforms, or conduct research involving mapping, particularly topographic maps.
