Mars is the planet most like Mother Earth.
bec. of the gravity of the earth
Answer: It keeps up from being crushed from the atmosphere around us... it also keeps us from floating away and helps keep the earth the right temp. Answer: Gravity keeps the atmosphere around the planet in the first place.
All of them do. There's no planet where the gravity is the same as on Earth.
Planet Earth - about 80%.
Io is a moon of Jupiter, not a planet. Surface gravity is about 18% of the gravity on Earth.
Earth: Space: - is a planet - No gravity - supports life - Vaccum - gravity - No gravity or atmosphere - atmosphere
Earth- since so far, it is the only planet that has a combination of gravity, temperature, water and atmosphere where people can live.
Gravity
temperature, gravity, atmosphere, and water
The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).
bec. of the gravity of the earth
A magnetic field holds atmosphere to the planet. Without a magnetosphere the solar wind from the sun will blow the atmosphere away. That is why our planet still has an atmosphere, we have the magnetic poles.
The atmosphere is held in place by the earth's gravity. Gravity is related to mass, the more mass a planet has, the more gravity. A much smaller planet like mercury or a body such as the moon will have less gravity, not enough to hold an atmosphere - the gravity is not strong enough to prevent the gas particles from escaping into space.
Earth contains a five layer atmosphere. It is due to gravity.
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.

The Earth's gravity keeps the gasses in the atmoshere drawn to the planet.
