Erosion and Weathering Concepts

The video tutorial covers a Grade 6 science lesson on forces that shape the Earth. It includes a worksheet from the workbook, page 118, with fill-in-the-blank questions. The teacher provides instructions for completing the worksheet, presents the questions, and then goes over the answers. The lesson focuses on concepts like physical and chemical weathering, erosion, deposition, and the role of water and wind in these processes.
