Segments in this Video

Moon and Tides (04:29)

FREE PREVIEW

What would happen on Earth if there were no moon? Giant waves would batter land masses around the world. Two massive waves would be initiated on opposite ends of Earth.

Tilt of the Earth (03:45)

The moon locks the Earth's tilt, as it acts as a large stabilizer. Without the moon, Earth's stable seasons would shift dramatically. Humanity and all life forms would be disrupted by the Earth's ever-changing tides and climates.

Early Era of Planet Earth (04:32)

Of the 150 moons in solar system, Earth's moon is unique. It is a huge moon. Over four billion years ago, the planet Earth had no moon and was a mass of volcanism and gas.

Earth's Moon (02:33)

About ten million years after the moonless Earth began taking shape, a Mars-sized planet collides with the planet. The blast launches 70% of Earth's crust into space. Within one year all the materials coalesce into Earth's moon.

Earth's Core (02:49)

After a cataclysmic collision by a planet, Earth absorbs the impactor planet's core. Earth's larger molten core takes longer to cool than the original one would have, and it might have helped create the sustained tectonic system that forms Earth's continents.

Dance Between Earth and Moon (02:41)

Early Earth's newly formed moon is much closer and causes tidal forces that lift molten lava 1/2 mile high twice a day. The complex gravitational dance between Earth and the moon pushes the moon away from Earth.

Early Earth: Weather and Oceans (04:01)

Without Earth's moon, humans might not have come into existence. Planet Earth is mostly covered with water. Massive oceans have virtually no tidal changes. Earth rotates 3 times faster and experiences violet weather.

Early Earth's Conditions (03:12)

Early Earth's fast spin creates a stronger magnet field that it has today. Without the moon, the developing Earth experiences intense climate volatility. Earth's conditions would have paralleled what happened to Mars.

Climate of Early Earth (02:56)

If the moon never existed to stabilize Earth, the planet would be an alien place. More jet streams and turbulence would occur. Earth would have suffered the ravages of ever-shifting climate

Life Forms on Early Earth (05:11)

With shifting climates on early Earth, evolutions vary from bursts of adaptation to violent extinction. Bacterial life survives the changes. Life forms look very different than they do today because of necessary adaptations to a hostile planet.

Development of Life Forms (04:23)

The collision of the developing Earth with a Mars-sized planet make possible complex life forms on Earth today. Enormous tides wash over the land, carrying minerals and soil back into the sea. Intertidal zones are ideal for development of life forms.

Earth in Equilibrium (02:09)

Over billions of years, Earth seems to have reached a perfect equilibrium that has allowed for the evolution a diverse, intricate, and fragile ecosystem. Though the moon stabilizes Earth, it continues to recede from Earth by 1.5 inches per year.
