Why there is an atmosphere around the earth while many planets don't have?
Answers
Explanation:
Actually, other planets in our solar system do have an atmosphere – certainly Venus and Mars do. The gas giants are in a sense all atmosphere.
The moon however, doesn’t have atmosphere. Basically this is because it is sufficiently small that the force of gravity on the moon is so weak that it can’t hold on to any gas...!!
Earth has more atmosphere than most of the other inner planets for three reasons.
Gravity
Volcanism.
Temperature
Being the most massive of all of the inner planets, Earth can hold more atmosphere to its surface by its gravity alone. Furthermore, volcanos continually spew out gasses into the Earth's atmosphere at a rate faster than they escape into space. Temperature is a big factor : if a planet or moon is too cold, then the atmosphere will freeze and fall to the surface.
Pluto spends part of its orbit with an atmosphere, but when it’s furthest away from the Sun it freezes. On Earth, the amount of energy coming in from the Sun and being lost to space is about the same, meaning that the planet can stay at a constant temperature...!!
