In an obscure corner of the universe, a relatively unremarkable galaxy shows signs of planetary progress. These violent growing pains are just a precursor of Earth's internal struggle to define itself. Driven by the dynamo of molten magma and plate tectonics, the ocean floor rips apart, continents collide, mountains rise and volcanoes erupt.

Wind, water, and ice are the natural elements that have eroded and rebuilt the Earth. Now, take a geological journey through time to examine these destructive forces and their impact.
