During the formation of the Earth, various gases were released from the surface, including carbon dioxide, nitrogen, and water vapor. Once the Earth reached a large enough mass, it had enough gravity that these gases didn't drift off into space; they were held to the surface by gravity. Earth's magnetic field also helps to keep the atmosphere on Earth, by shielding it from solar winds that would otherwise bombard the atmosphere and send its gases into space.
The Moon has no atmosphere because its mass is too low, and thus it doesn't have enough gravity to hold onto an atmosphere. In addition, it has no significant magnetic field. Mars may have once had a much denser atmosphere, but it lost its magnetic field billions of years ago, and solar winds eroded the atmosphere until it became very thin, like it is today.

Do all objects fall towards the center of the earth?
All objects on earth are pulled towards the center of the earth by gravity. The objects are pulled to the core(center of earth), but are not pulled through because of the normal force.
Why don't satellites get pulled towards the Earth's surface?
Because of the gravity that Earth has with the moon; Satellites are out of the gravity pull that surrounds Earth, therefore, they are not sucked in.
Why do humans not get pulled towrd the sun instead of the earth?
because people have a smaller mass than that of earth, they are attracted into earth's gravitational field. Theoretically, Earth is moving closer to the sun every day, so we technically are moving towards the sun.
Would the Earth change if the Sun's gravity increased?
Yes. If the gravitational pull of the Sun grew stronger, the Earth would be pulled towards the Sun, making our planet lethally hot, somewhat like Venus.
What satellite that revolves around the earth?
The satellite is pulled towards the Earth by the force of gravity, but it also has it own high velocity in its orbit. As it accelerates downwards towards the centre of the Earth, its velocity keeps track of the Earth's curvature, so it actually stays at the same height constantly.
What are objects on earth pulled to?
Towards the Earth.

Why are planes pulled toward water?
They aren't. They are pulled towards the center of the earth, as are all objects on the surface of the earth.

How fast are you pulled towards the Earth's surface?
pulled means that we are attracted toward the earth which is gravity an that is 9.8 metre per second square
Why are birds not pulled towards earth?
They are! It's sort of hard to explain, but picture and airplane. Birds are pulled down just as much as planes are. But by pushing air under their wings they keep themselves up. Haha. Hope that helps.
Why does Air stay within the Atmosphere - solid and liquid are pulled by gravity BUT i don't agree Air is pulled by gravity?
First of all, the atmosphere is the air. Secondly, air is matter, all matter is affected by gravity. Imagine this: the sea is liquid, it lies on the earth, pulled by gravity. the atmosphere is also like this except it is a "sea" of air, it lies on the earth, pulled by gravity.
What is happening when you has jumped out from the aircraft but you not yet open your parachute?
you will be pulled towards the earth by the force of gravity
Why don't satellites get pulled towards the Earth's surface?
Because of the gravity that Earth has with the moon; Satellites are out of the gravity pull that surrounds Earth, therefore, they are not sucked in.
How meteor hits the earth?
While travelling through the solar system it comes near the earth and is captured by the earth's gravity. It is pulled towards the earth until they collide.
How you are staying on earth as earth is round?
Gravity.The gravity of the earth is always pulling everything towards it. Nothing can fall off the earth because everything wants to fall towards the center of the planet.Even the moon is being pulled towards the earth. That's the only thing that keeps it from drifting off into space.
