Our second "4 Winds" lesson was all about erosion. Addison's mom and Gunner's mom taught us all about the forces that create erosion. We looked at how, over time, the powerful agents of erosion have shaped and formed our landscape. Gravity, water, wind and ice are constantly weathering, wearing away and moving rocks, soil, sand and sediments, and depositing them elsewhere. We had a lot of fun exploring different ways in which erosion takes place.
