Review and connect weathering, erosion, deposition, rock layers, fossils, and the causes of earthquakes and volcanoes as related Earth surface processes.
This unit covered how Earth's surface constantly changes: weathering breaks rock down, erosion moves it, and deposition drops it somewhere new. Those same deposited layers can harden into rock over time, stack up in an order that reveals their age, and preserve fossils that show how life and environments have changed.
You also studied two of Earth's more sudden processes: earthquakes, caused by stress suddenly releasing along a fault, and volcanoes and mountains, built up over time by plate movement or repeated eruption. This week connects all of it together, since slow, gradual change and sudden, dramatic change are both part of the same restless planet.
Mastery looks like: They can correctly sequence weathering, erosion, and deposition, connect rock layers to fossil evidence of change, and describe earthquakes and volcanoes as additional Earth-changing processes.
Common stumbles: Treating slow and sudden Earth processes as unrelated instead of both being ways the same planet reshapes its surface; losing the correct order of weathering, erosion, and deposition.
