Learners will understand: The types and causes of weathering (mechanical, chemical, and biological). The agents of erosion, including rivers, glaciers, waves, and wind. How weathering and erosion affect land forms, soil formation, and human activities. The importance of soil conservation and methods used to reduce erosion in Ethiopia. By the end of this section, students will be able to describe how weathering and erosion continuously change the Earth’s landscape and identify practical ways people can protect land resources.5
