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.

Motion

53m 40s

The forces of nature have kept Earth on the move since it was formed billions of years ago. Though we can’t feel the motion, we experience the consequences, from tidal bores surging through the Amazon rainforest to the ruinous power of hurricanes.
