That's gravity. Near the surface air has a density of about 1.2Kg/m^3. Air isn't that lightweight as you might think. We usually just don't lift it, but push it away, which is much easier.
Earth is able to retain its atmosphere due to its gravity. The gravitational force of Earth is strong enough to hold on to the gases of the atmosphere, preventing them from escaping into space. This creates a stable environment that allows for life to exist on the planet.
Gravity hold the atmosphere to the Earth. But other factors do cause earth to loose some atmosphere to space continuously.
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.
Gravity is what keeps oxygen (and other gases) from escaping Earth's atmosphere. The gravitational force of Earth is strong enough to hold on to gases in its atmosphere, including oxygen. This allows for the maintenance of a stable and breathable atmosphere on the planet.
The main atmospheric gases that help hold the Earth's atmosphere in place are nitrogen and oxygen. These gases are constantly present in the atmosphere and provide the necessary pressure to keep the atmosphere close to Earth's surface. Additionally, small amounts of other gases like carbon dioxide, methane, and water vapor also contribute to trapping heat and maintaining Earth's temperature.
Gravity holds the atmosphere around the planet. Gravity is the force that attracts a body toward the center of the planet. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
because the gravitational attraction of moon is very low(about 1/6th of earths') which is not sufficient to hold the air molecules to form atmosphere.
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.
Luna, the Earth's moon, has no atmosphere at all. Its force of gravity is too small to hold an atmosphere to its surface.
Earth is able to retain its atmosphere due to its gravity. The gravitational force of Earth is strong enough to hold on to the gases of the atmosphere, preventing them from escaping into space. This creates a stable environment that allows for life to exist on the planet.
Mercury, because the gravity on it is to small to hold any atmosphere in the first place.
Gravity hold the atmosphere to the Earth. But other factors do cause earth to loose some atmosphere to space continuously.
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.
Gravity is the force that pulls objects toward each other, and it plays a crucial role in holding the Earth's atmosphere in place. The Earth's gravitational pull attracts air molecules, preventing them from drifting off into space. This force ensures that the atmosphere remains dense enough to support life and maintain weather patterns. Without gravity, the atmosphere would dissipate, leaving the planet exposed to the vacuum of space.
Earth holds its atmosphere due to the force of gravity. Gravity pulls the gases of the atmosphere towards the surface of the Earth, preventing them from escaping into space. The Earth's gravity is strong enough to hold gases like nitrogen, oxygen, carbon dioxide, and others close to its surface.
Earth's gravity is considered strong compared to other celestial bodies within our solar system. It exerts a force of about 9.8 m/s^2, which is sufficient to keep our atmosphere in place and hold everything on Earth's surface.
Yes tho, my book says something like that I how I see here, yes.
