Changing Landforms

Landforms are constantly changing. This unit helps students understand what landforms are, how they form, and how different forces shape them over time. It introduces students to Earth's structure, including the crust, mantle, and core. Hotspots and earthquake patterns are addressed, as well as how weathering, erosion, and people shape the land. The unit also addresses the three major categories of rocks--igneous, sedimentary, and metamorphic--and explains how one rock type may change into another.
