Why do outer planets have a thicker atmospheres than the inner planets?

Gravity is the force that keeps an atmosphere in place, surrounding a planet. Since there is no actual roof or container holding in the atmosphere, gas can always leak away into outer space, if it is not held in place by gravity. So the stronger the gravitational force, the more atmosphere can be retained. Large planets have a lot of hydrogen in their atmosphere, but hydrogen leaks away from smaller planets. Large planets attracted more gas when they were originally formed, as well. Remember that the solar system itself, and everything in it, originally condensed out of an interstellar cloud of gas and dust.
