2. Describe factors that cause changes to Earth's surface over time.
Examples: earthquakes, volcanoes, weathering, erosion, glacial erosion or scouring, deposition, water flow, tornadoes, hurricanes, farming and conservation, mining and reclamation, deforestation and reforestation, waste disposal, global climate changes, greenhouse gases Comparing constructive and destructive natural processes and their effects on land formations
constructive—volcanic and mountain-building processes;
destructive—erosion by wind, water, and ice Distinguishing rock strata by geologic composition
Examples: predicting relative age of strata by fossil depth, predicting occurrence of natural events by rock composition in a particular strata
