Shaping the World through Rain, Wind, and Ice: External Factors that Make Our World
This video lesson looks at external factors that shape the Earth's landforms: weathering, erosion, and deposition. This examination of physical geography and geology aspects of the world includes looking at the differences between chemical and physical (or mechanical) weathering, how rain, wind, ice (glaciers), and even gravity moves sediment, and then how deposition of sediment creates landforms such as river deltas as well as produces fertile areas such as the North European Plain through the deposition of loess.
In addition, a review of what soil is and how it is created is included as well as how these processes create sedimentary rock.
This lesson is designed to not only inform all audiences, but also to focus on the Texas Education Knowledge Standards for the World Geography studies course.
