Due to earth's gravity, the atmosphere isn't escaping.
the clouds in the atmosphere act as a blanket keeping warm air from escaping the atmosphere
It keeps the sun's warmth from escaping by the greenhouse effect
The planet's strong force of gravity holds the atmosphere down and stops it escaping. Atmospheric gases have masses, and the Earth's atmosphere has a mass of about 1.2 kg per cubic metre.
They stop heat from escaping the atmosphere- apex
The atmosphere stays around the Earth due to gravity. Gravity is the force that pulls the gases in the atmosphere towards the Earth's surface, keeping them from escaping into space.
Burning coalmakes a gas that stop the suns heat from escaping the atmosphere.
the gravitational force holds its atmosphere together
carbondioxide [CO2] and carbondioxide [CO] are the main gasses that trap heat.
Gravity holds a planet's atmosphere close to its surface. The gravitational force of the planet's mass prevents the gases in the atmosphere from escaping into space. Without gravity, the atmosphere would disperse into space.
Asteroids are too small to have enough gravity to prevent any atmosphere form escaping.
Earth's gravity is the main force preventing oxygen from escaping into space. The atmosphere also plays a role in trapping oxygen through a combination of molecular interactions and the presence of other gases. Additionally, the magnetosphere helps shield Earth's atmosphere from the solar wind, which could strip gases away.
Carbon dioxide traps the heat in the atmosphere of Venus and prevents it from escaping in to space (Venus contains a great amount of Co2 in its atmosphere). That's why, Venus is known as the hottest planet in the Solar System.
