Forces of Nature

"Forces of Nature" illustrates how we experience Earth's natural forces, including shape, elements, color and motion. Although we can't immediately feel the motion of Earth's fundamental forces, we witness the consequences, such as tidal bores surging through the Amazon rainforest or the intense and ruinous power of hurricanes.

    S1 E2 - 54m 11s

    The forces of nature make Earth a restless planet, but they also turned our ball of rock into a home for life. How did our planet’s ingredients, the chemical elements, come together and take that first crucial step from barren rock to a living world?

  • Shape: asset-mezzanine-16x9


    S1 E1 - 54m 11s

    We can’t directly see the forces that govern Earth, but we can see their shadows in the shapes of nature that surround us. If we understand why these shapes exist, we can understand the rules that bind the entire universe.
