Summary: Much of the Earth would be uninhabitable without wind. This Science Screen Report studies air in motion and the crucial role of that dynamic, ever-present phenomenon. Illustrating how varying temperature and atmospheric pressure create wind, the program examines local examples in the form of offshore and onshore breezes, as well as global patterns like the trade winds and westerlies. Includes...

Summary: Planet Earth is an amazing machine, and we-and our future-are riding on it. This video introduces students to the Earth system's primary interacting subsystems (the biosphere, geosphere, hydrosphere, and atmosphere); the nitrogen, carbon, and water cycles; and three surface processes: weathering, mass-wasting, and erosion. The greenhouse effect, the impact of acid rain on the environment, and...
