Landforms and Weathering. Grade 5 Goal 2 EOG Tested. Major Unit Goal/Learning Outcomes. Students should be able to: Describe how forces change landforms over time Rate the effects of weathering forces Understand how water movement shapes landforms Describe the characteristics of landforms
When water is frozen it expands, so when water seeps into cracks in rocks then freezes, the expanded ice can cause the rock to split and crack. This process is known as ice wedging and it can reduce a rock to rubble over time.

The result is topography with extremely
flat surfaces that aggrades with each
successive lava flow.
