Neptune's atmosphere is mainly Hydrogen (around 80%), Helium (around 19%) and Methane (around 1%).
Jupiter's atmosphere is mainly Hydrogen (around 90%), Helium (around 10%), with small amounts of Methane, Ethane, Water and Ammonia.
Saturn's atmosphere is mainly Hydrogen (around 96%), Helium (around 3%), with small amounts of Methane, Ethane and Ammonia.
Uranus' atmosphere is mainly Hydrogen (around 83%), Helium (around 15%) and Methane (around 2.3%).

Why are the inner planets so much smaller then the gass giant outer planets?
They believe that the inner planets had gases at one point in time, but the sun burned them away.
How does the composition of earths atmosphere differ from the composition of the atmospheres of the gas giant planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
What are two types of planets an be found in our solar system?
There are the four smaller, denser, inner, rocky, terrestrial planets. then there are the four outer gas giant planets.
What planet do scientists believe is a giant ball of gas?
There are four planets that are considered giant gas planets: Jupiter, Saturn, Uranus, and Neptune. All of them are much larger than Earth, and wrapped in an envelope of gases of unknown depth. Sometimes Uranus and Neptune are called "ice giant planets". So, you could say there are, perhaps, only two real "giant gas planets". They would be Jupiter and Saturn.
How the sizes of the inner planets compare to the sizes of the gas giant planets?
The inner planets are smaller than the gas giant (outer) planets.
What other planets has analogy similar to Jupiter?
All of the gas giant planets are similar: Jupiter, Saturn, Uranus, and Neptune. They differ mainly in size and the concentration of certain gases in their atmospheres.
What gases are giant planets made of?
Mainly hydrogen and helium.
What are the giant planets mostly made of?
Hydrogen and other gases.
What are the giant outer planets made mostly made out of?
Gases
Do the gas giants have thinner atmosphere than the terrestrial planets?
No. As the name gas giant implies, these planets are made largely of gas. They have extremely thick atmospheres.
Why do different planets have different atmospheres?
All the sun's planets probably had similar atmospheres when they first formed, billions of years ago. The most common gases were the light gases, hydrogen and helium, with smaller amounts of oxygen, nitrogen and other gases. The immense gravity of the giant planets, Jupiter, Saturn, Uranus and Neptune, was able to hold the hydrogen and helium, which remain the predominant gases in their atmospheres, along with methane formed by the combination of hydrogen with free carbon. However, hydrogen and helium gradually escaped from the atmospheres of the smaller planets, where gravity is insufficient to hold the light gases permanently. Even the heavier gases, such as oxygen and nitrogen, as well as carbon dioxide and water vapour, can gradually escape from smaller planets, such as Mars and Mercury. So, these planets now have quite thin atmospheres. The Moon and other small bodies in the solar system have essentially no atmosphere. In our solar system, only the Earth and Venus are the right size to lose most of the light gases, while retaining gases such as oxygen, nitrogen, carbon dioxide and water vapour.
What type of gases makes up the giant planets?
Hydrogen and helium mainly. The 'Outer Planets' are composed of a rocky, metallic core with a thick layer of gas surrounding. As such, they are less dense than the 'Inner Planets' also called the 'Terrestrial (earth-like) Planets' which are mainly rock, ice and metal with thin atmospheres of carbon dioxide, nitrogen and in the case of the Earth: oxygen
How is Jupiter made of?
Jupiter is mostly made of gases like methane and other gases like most outer giant planets
Is Jupiter made of?
Jupiter is mostly made of gases like methane and other gases like most outer giant planets
What feature separates the rocky planets from the gas planets?
Depth of the atmosphere. Gas planets have the thickest and largest of atmospheres. Below gas planets atmospheres are pools of hydrogen or in some cases volatile ices that form in a giant ocean above the surface. It's estimated that Jupiter's rocky surface is only about the size of three Earths but the bloated atmosphere makes for most of the planet.
Why are the inner planets so much smaller then the gass giant outer planets?

How does the composition of Earth's atmosphere differ from the composition of the atmospheres of the gas giant planets?
The Gas Giants have a deep gas atmosphere and earth have a not so deep atmosphere
