At first glance, sand dunes appear to be permanent features of the landscape, but they are actually in constant motion. In this video, we explore the fascinating science behind why sand dunes seem to move almost like living things. Driven by wind, gravity, and the movement of countless individual grains, dunes slowly migrate across deserts, beaches, and coastlines over time. Some dunes can even move several meters each year, changing shape and position while interacting with neighboring dunes in surprisingly complex ways.

This episode dives into geology, physics, earth science, fluid dynamics, weather systems, and the hidden forces that shape landscapes around the world. We also explore how different dune formations develop, why some dunes appear to "communicate" through their movements, and what these ever-changing structures reveal about  ...
