Yes. Both Mars and Venus have weaker gravity than Earth does, but still have atmospheres. Mars has a very thin atmosphere which may have been close to the density of Earth's atmosphere in the distant past, despite having less than half the surface gravity. Venus has about 90% the surface gravity that Earth does, but has an atmosphere many times denser than Earth does.
What else can I help you with?
If you pump all the air out of a room would there still be gravity?
Yes, there will still be gravity. The floor beneath you is still pulling you down towards the earth.
When you throw a substance in air at what height there in no gravity at what height there is least gravity and at what height there is normal gravity?
The farther it is from Earth, the less gravity will there be. Gravity will never completely disappear.
Are you still moving if you stay still?
yes, because of the earth's gravitational pull and the air slightly moving you back and forth, it does this by not wind but by gravity. the gravity makes the air make a very slight breeze making you very lightly sway. so basically air + gravity = movement.
Does gravity affect the air we breathe?
Yes, gravity affects the air that we breathe. That is why it is harder to breathe when we go up high mountains. There is less air there. Without gravity, the air would float off into space, just as we would.
Why don't any other planets have any air and gravity?
All planets have gravity- Some more than Earth, some less. Other planets that are large enough do have air- but not made up of the same gasses as Earth.
Why is there less air pressure on top of a mountain than near an ocean?
Because - the further away from the Earth's surface you go - the less gravity there is to hold the air molecules in place.
Why doesn't air get caught in gravity?
It does. That's why it's still here, and has not completely departed from the Earth yet.
Why is there most air closer to the surface?
Most of the Earth's atmosphere is concentrated near the surface due to gravity. The force of gravity pulls air molecules towards the Earth, making the air denser at lower altitudes. As you move higher in the atmosphere, the air becomes less dense because there are fewer air molecules present.
Is a ball thrown up in the air a gravitational force?
Yes, when a ball is thrown up in the air, gravity is still acting on it. Gravity is the force that causes objects to be pulled towards the center of the Earth.
Why does air become less dense as you increase altitude?
gravity, denser things go down. -earth science student
Is their gravity on the moon?
Yes. The moon is less massive and smaller than Earth, so the force of gravity on objects near the moon's surface is less than on Earth. The gravity of the moon is around 1/6 the gravity of the Earth. The acceleration of gravity on the moon is 1.6 meters per second per second.
Does the temperature increase as you get higher up in the atmosphere?
As you get higher up in the atmosphere there is less and less air on top of your head so there is less weight, meaning there is less pressure. Gravity. Atmosphere will be more compact closer to Earth because particles in the air have mass and are thus pulled down by gravity.
