Why do inner planets have thinner atmospheres than the outer planets?
Wiki User
∙ 11y ago
An atmosphere is a layer of gas that surrounds a planet; this gas is attracted by gravity and is greater in volume depending on the strength of the gravitational field and the temperature of the atmosphere.
The inner planets generally have less mass, resulting in a less strong gravitational field, and a warmer atmosphere meaning the atmosphere is thinner than the colder, larger outer planets.

Which planets in the solar system are referred to as the inner planets and outer planets?
The 4 Inner planets (mostly rocky and solid):MercuryVenusEarthMarsThe 4 Outer planets (mostly dense gaseous atmospheres):JupiterSaturnUranusNeptuneNotes:Pluto, a dwarf planet, was an outer planet before it got reclassified, but resembles the inner planets.The inner and outer planets are separated by the asteroid belt.When dwarf planets are included, Ceres counts as an inner planet and all the other dwarf planets count as outer planets.
Do outer planets have atmospheres?
Yes
What are two similarities about the inner and outer planets?
The inner planets, otherwise known as the terrestrial planets all are: -rocky/more dense (unlike the gaseous outer planets) -closest to the sun -smallest planets
Inner an outer planet similarities?
The inner and outer planets are The same because The Inner planets are not made out of gas The outer planets are bigger than inners The outer planets are the coldest The Inner planets are rocky The inner planets are terrestrial The outer planets can't support life The inner planets have iron cores The outer are the furthest from the sun The outer planets haveno rocky surface
How do the inner and outer planets atmosphere different?
the outer planets are gaseous and the inner planets are not
Do inner planets have thicker atmospheres than outer planets?
no
What characteristics distinguish inner plants from outer planets?
Mainly, they are closer to the Sun, hence the name. Also they are smaller and therefore have much thinner atmospheres, so they show their rocky exteriors, hence they are known as the rocky planets.

Do only the inner planets have atmospheres?
Negative, not only do the inner planets have atmospheres, but the outer planets also have atmospheres. The masses of the outer planets are great, enough easily to hold an atmosphere. In fact it's Mercury, an inner planet, that has almost no atmosphere. True, Mercury has a less mass and the closeness to the sun make it impossible to hold on a atmosphere. As matter in fact, Mars had a atmosphere, but the solar wind had almost eaten all the atmosphere that Mars had.
What is the main difference between the inner planets and the outer planets?
The inner planets are smaller, and do not have the dense atmospheres of the outer planets. The four inner planets (Mercury, Venus, Earth, and Mars) have warmer temperatures than the exteriors of the outer planets (Jupiter, Saturn, Uranus, and Neptune).The "gas giants" have very hot lower atmospheres, caused by the intense pressure. The atmospheres are mostly hydrogen, but for Uranus and Neptune there are higher levels of water, methane, and ammonia. All of the gas giants have multiple moons and rings, the most visible being the ice rings around Saturn.they are divided by inner and outer and the outer planet are the planets that have bigger planets.
Why are inner planets different than outer planets?
Inner planets. are inner & outer planets. are outer

What planets have atmospheres?
Inner Planets = Earth Venus Mars Outer Gas Giants = Jupiter Saturn Neptune Uranus So therefore, Mercury isn't included.
Why do you compare outer planets to inner planets?
because inner planets are hot and outer planets are cold
