Visualizing the Past
Visualizing the Past is a skill on Pengi from Lesson 2: Landforms as Evidence in Amplify Science (California) Grade 7.
Key Concepts
Geologic processes are often temporary, but the landforms they create are persistent. A river may dry up, but the riverbed remains carved into the rock for eons.
This persistence means that landforms act as a record of the past. By analyzing the shape, size, and texture of a landform, scientists can reconstruct the geologic history of a region. They look at a dry landscape and see the "ghosts" of the water or lava that once flowed there.
