One Strange Rock: Storm. -
Rory and I watched the end of the of ‘One Strange Rock’ episode two: Storm. This episode starts with the ferocious early days of our solar system, and the onslaught of meteor showers that helped mold this planet. It illustrates how, some four billion years ago, the Earth had a twin - which traveled in the same orbit around the sun. Eventually the two planets collided and the result was the Earth and moon. The moon controls the tides, which, in turn influences the climate. The collision knocked the Earth off its axis, so that our planet is not facing the sun straight on, like many other planets. This tilt is responsible for our seasons, and the seasons, along with the tides, keep water flowing. It was the water storm, the planetary collision, and the perfect distance from the sun, which makes Earth the living planet.
