Today we learned about the difference between weathering and erosion. We read about it and then did some hands on learning about how wind, water and ice can erode soil and rocks. After creating landforms and dripping or pouring water on them, we decided that sand is easier to erode than bigger rocks, and that more water moving faster was more likely to cause erosion. We made some conclusions about wind and ice too. Next time we will see if gravity plays a role as well.
