When earth atmosphere formed what gases were lost because earth gravity was too weak?
When Earth's atmosphere first formed, lighter gases such as hydrogen and helium were lost to space because Earth's gravitational pull was not strong enough to retain them. These gases escaped into the atmosphere primarily due to solar radiation and the planet's high temperatures during its early formation. As Earth cooled, it retained heavier gases like nitrogen, carbon dioxide, and water vapor, which contributed to the development of a more stable atmosphere.
What else can I help you with?
What area marks the boundary where the earth's atmosphere is constrained by gravity?
There is no boundary where Earth's atmosphere is constrained by gravity. Many feel that astronauts orbiting above the Earth are weightless because they are far away from Earth's gravity , but weightlessness is actually caused by the free-falling of an object that is in orbit.
What holds the atmosphere to the earth?
The earths gravity. The more mass a body has, the more gravity, The Earth has enough mass to hold an atmosphere. The Moon, on the other hand, is not massive enough, and so does not have a high enough gravity, which prevents it from holding an atmosphere.
Why is there no gravity outside your atmosphere?
There certainly is gravity outside the atmosphere. For example, it is gravity that keeps the Moon in orbit around the Earth, and the Earth in orbit around the Sun.
How is the atmosphere effected by gravity?
Gravity causes the atmosphere to stay here on Earth, where there is a huge demand for it.
How can the moon have gravity when there is no atmosphere?
Gravity has to do with the amount of mass an object has; not an atmosphere. The bigger the object, the stronger the gravitational pull. That's why people feel lighter on the moon than they do on Earth.
The atmosphere remains near the earth because?
Gravity.
Why their is no air in space?
The atmosphere we breath is held round the earth's surface due to earth's gravity. Without this gravity, earth's atmosphere would disperse into space. Because our moon's gravity is weak, so there is no atmosphere on the moon.
Are molecules of atmosphere pulled towards the earth because of gravity?
Yes. Molecules have mass and are therefore affected by gravity. Were it not for this, there would be nothing to keep the atmosphere on Earth.
How are earth and Mars are alike and different?
earth and mars are like and different because they have a atmosphere and gravity
Why is space not like earth?
Earth: Space: - is a planet - No gravity - supports life - Vaccum - gravity - No gravity or atmosphere - atmosphere
Explain how earth's mass is related to its ability to have an atmosphere?
The Earth has an atmosphere because it has the gravity necessary to keep the gases from floating off into space. The more mass a planet has, the more gravity it has, and the more gravity it has, the thicker an atmosphere it can sustain.
Is earth atmosphere under pressure?
Because there is gravity, that pulls stuff to the core.
Is it true or false that the atmosphere remains near the earth because of gravity?
true
Why does the atmosphere of the Earth float above the planet's surface?
The atmosphere of Earth is held in place by gravity. Gravity pulls air molecules towards Earth's surface, creating atmospheric pressure that keeps the atmosphere from floating away into space.
Gas molecules in the atmosphere are pulled toward the earth by what?
gravity pulls gas molecules down to earth because the force of it keeps us on the earth
The atmosphere is held in place by Earth's .?
gravity
Which force holds the atmosphere to the earth?
The force that holds the atmosphere to the Earth is gravity. Gravity is the force of attraction between all objects and it keeps the gases in our atmosphere close to the Earth's surface.
