## Why don t the oceans fall off the Earth?

The tilt of the Earth compared to the imaginary disk of its orbit includes its water. That water doesn’t spill away from the Earth; it’s already spilled onto and into the Earth, so it’s part of the Earth, just as the atmosphere is — the water stays here because down means toward the center of the sphere.

## Why does water stay in the ocean?

In the deepest parts of the ocean, you’ll find layers of Earth’s crust make up the ocean floor. These deepest layers are made up of rock and minerals. Unlike the soft sands along the shoreline, these deep layers of thick rock and minerals do a fine job of holding the water in the world’s oceans.

What keeps the oceans in place?

As gravitational force acts to draw the water closer to the moon, inertia attempts to keep the water in place. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean’s waters toward it, creating one bulge.

Why don’t we fly off the earth?

Normally, humans aren’t thrown off the moving Earth because gravity is holding us down. However, because we are rotating with the Earth, a ‘centrifugal force’ pushes us outwards from the centre of the planet. If this centrifugal force were bigger than the force of gravity, then we would be thrown into space.

### What draws water back to the earth?

Condensation and gravity are the two driving forces that draw water back to Earth.

### What if Earth rotated backwards?

Short answer – the reversed spin would make the Earth much greener. Long answer – this new rotation would change winds and ocean currents, and that would shift the planet’s climate entirely. Instead, a different current would surface in the Pacific and become responsible to distributing heat around the globe.

What happens if the Earth spins faster?

The faster the Earth spins, the shorter our days would become. With a 1 mph speed increase, the day would only get about a minute and a half shorter and our internal body clocks, which stick to a pretty strict 24-hour schedule, probably wouldn’t notice.

How does it enter the soil?

Nutrients get into the soil many different ways: from decomposed animal waste and dead plants, the atmosphere, weathering of rocks and bacteria conversions.

#### Where is most of the water on Earth stored?

The oceans
The oceans are, by far, the largest reservoir of water on earth — over 96\% of all of Earth’s water exists in the oceans.
