How does gravity keep the ocean in place?
Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides.
Can gravity holds water in the ocean?
This attraction causes the water on this “near side” of Earth to be pulled toward the moon. As gravitational force acts to draw the water closer to the moon, inertia attempts to keep the water in place. In this way the combination of gravity and inertia create two bulges of water.
How does gravity keep water down?
Gravity is the force of attraction between two objects, and Earth’s gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water.
How does the water not 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.
How does gravity play a role in moving water in the water cycle?
Gravity causes precipitation to fall from clouds and water to flow downward on the land through watersheds. Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs. As the water is heated, it changes state from a liquid to a gas. This process is called evaporation.
Can birds fly in 0 gravity?
Again, I suppose my answer to you would be: Yes, a bird can technically still fly in zero gravity. Even while everything can technically float in zero gravity, birds would be still much more viable at controlling themselves mid-air with their wings.
Is gravity stronger over water?
Faced with this choice, gravity will act more strongly on whichever has more mass (thus, more weight) per given volume. So if the thing you immerse is denser than water it will sink, but its apparent weight is reduced by the volume of water that gets displaced upward.
How is water held to the earth?
The ocean holds about 97 percent of the Earth’s water; the remaining three percent is found in glaciers and ice, below the ground, in rivers and lakes. Of the world’s total water supply of about 332 million cubic miles of water, about 97 percent is found in the ocean.
How does most ocean water return to the ocean in the water cycle?
Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with streamflow moving water towards the oceans.
How does water get from the oceans onto land?
How does water get from the oceans onto land? Ocean water evaporates to form gaseous water and moves into the atmosphere, where it condenses into liquid water and falls out of the atmosphere to land as rain.
Why can a butterfly hover on the surface of the ocean?
Because the butterfly produces an upwards force to counteract gravity while the ocean does not. Gravity pulls everything down at around 9.8m/s/s, so if you have a 1kg bucket of water, you would have to provide 9.8 Newtons of force upwards to counter the effect of gravity and hover.
Does gravity hold the water at the bottom of the Earth?
What this means is that the Earth has no bottom for water to be held onto. Thus gravity doesn’t hold any water onto the bottom of the Earth. The fish can still swim freely because they’ve developed ways of moving through dense fluids.
What would happen if a butterfly stopped flapping its wings?
If a butterfly stopped flapping its wings, it would plummet back to Earth’s surface like a brick. As far as our oceans are concerned, there is no inherent mechanism within the oceans that can generate any type of lift, so our oceans are bound to the surface of the Earth by the force of gravity.
Why is there no water at the bottom of the Earth?
Gravity pulls the Earth into a sphere (well, an oblate spheroid, but close enough), so no matter where you are on the Earth’s surface, down is towards the planet. What this means is that the Earth has no bottom for water to be held onto. Thus gravity doesn’t hold any water onto the bottom of the Earth.
