Here’s a clear and engaging description you can use for Grade 8 – Social Studies – Unit 1: Weathering and Erosion (Part 2), following the Ethiopian curriculum context: In this part of Unit 1, students explore the natural processes that shape the Earth’s surface—weathering and erosion. The unit explains how rocks break down into smaller pieces through physical and chemical weathering, and how wind, water, and ice transport these materials from one place to another through erosion. 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
