Climate affects the rate of weathering. 3. Chemical weathering causes rocks to break into small pieces with each piece retaining the characteristics of the original. 4. Kaingin can cause soil erosion. 5. Plants and tress reduce the rate of soil erosion. 6. Gravity alone can erode the land, example in slope areas. 7. Soil are sediments, which are products of weathering and erosion. 8. Sedimentary rocks are formed through lithification of sediments over time. 9. Man can contribute to the process of weathering and erosion. 10. Weathering and erosion do not contribute to the fertility of soil.
