they are thick and gaseous, mostly hydrogen and helium. Most have very strong winds.

Do outer planets have atmospheres?
Yes
Which planets have a thick atmosphere?
Define thick - all 4 outer planets plus Venus have thicker atmospheres than Earth.
Why is the atmosphere thick in the outer planets?
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.
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.
Explain why the outer planets did not lose the light gases in their atmospheres?
In order for gas to leave a planet it needs to be hot enough and to overcome the planet's gravity. The outer planets are colder and are very massive in comparison to Earth.
Do outer planets have atmospheres?
Yes
Do inner planets have thicker atmospheres than outer planets?
no
What are the atmospheres of outer planets?
its made out of jaffa cakes
What is the two main gases of the atmospheres of the outer planets?
amonia, hydrogen,
Are space telescopes reveal many details of outer planets?
Yes they in fact do reveal some levels of the outer planets and their interior atmospheres.
Why are the farthest planets made of gas?
When the sun was young it released an intense solar wind. This prevented the inner planets from developing thick atmospheres like the outer planets. The outer planets, however, were spared from this fate, and were able to accrete large quantities of gasses.
What has the author Thomas W Scattergood written?
Thomas W. Scattergood has written: 'Chemistry of the outer planets' -- subject(s): Atmospheres, Outer planets
What do you call the four outer planets in our solar system?
They are called the "outer planets." But also the "gas giants" because they all have thick atmospheres and no accessible surface.
Are all of the outer planets gaseous giants with thick atmospheres?
I don't think so.
What characteristic do all of the outer planets share?
All of the outer planets are large in size, low in density, and have very thick atmospheres made primarily of hydrogen and helium.
Which planets have a thick atmosphere?
Define thick - all 4 outer planets plus Venus have thicker atmospheres than Earth.
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.
