The outer planets have thick atmospheres because they are so big. The bigger the planet, the stronger the gravitational pull. This means that the bigger planets pull in more gasses, which creates a bigger, thicker atmosphere.
Define thick - all 4 outer planets plus Venus have thicker atmospheres than Earth.
the outer planets are gaseous and the inner planets are not
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.
Outer planets and inner planets are compared because they have distinct differences in size, composition, and characteristics. Inner planets are smaller, rocky, and denser, while outer planets are larger, gaseous, and have thick atmospheres. Studying these differences helps scientists understand how planets form and evolve in our solar system.

Venus and the four outer planets all have a very thick and massive atmosphere.
the outer planets are gaseous and the inner planets are not
Inner planets, also known as terrestrial planets, are composed primarily of rock and metal, and include Mercury, Venus, Earth, and Mars. They generally have thinner atmospheres compared to outer planets, with Earth being the exception due to its relatively dense atmosphere that supports life. The atmospheres of inner planets can vary significantly; for instance, Venus has a thick, toxic atmosphere, while Mars has a very thin one. In contrast, outer planets are gas giants with thick atmospheres composed mainly of hydrogen and helium.
No, the inner planets are not necessarily warmer than the outer planets. While the inner planets are closer to the Sun and therefore receive more sunlight, factors such as atmosphere composition, greenhouse gases, and internal heat sources can also impact a planet's temperature. For example, Venus, the second planet from the Sun, is hotter than Mercury, which is closest to the Sun, due to its thick atmosphere trapping heat.
Yes, outer planets like Jupiter and Saturn have the greenhouse effect, but it is not as significant as on Earth due to their different compositions and much larger distances from the Sun. These planets have thick atmospheres with gases that trap heat, contributing to their overall temperatures.
The only outer planet without a thick atmosphere is Uranus. It has a thin atmosphere composed mostly of hydrogen and helium with traces of methane.
The outer planets does not have enough oxygen to sustain life, or they don't have an atmosphere at all.

All the outer planets, Jupiter being the thickest.
No. Only Venus has a really thick atmosphere. Mars has only a thin atmosphere and Mercury has almost no atmosphere.
