1. Why Jupiter, Saturn, Uranus and Neptune called gas planet?
Jupiter and Saturn are composed of mostly hydrogen and helium, with large mantles of metallic hydrogen (which acts like a metal, due to the pressure and temperature within these planets) and only small cores of rock and ice. This is why they are called gas giants: They are mostly gaseous, with very little rock and ice.Uranus and Neptune are composed of some hydrogen and helium, but they also contain heavier elements such as oxygen, carbon, nitrogen, and sulfur.
2. Based on what you know about outer planets, do you think these planet can sustain life just like earth?
The four outer planets are all gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. The outer planets have numerous moons, as well as planetary rings.
3. Why is Neptune called Uranus' twin planet?
With an orbital period of 164.8 years, Neptune has not yet completed its first full orbit since discovery. These two distant planets remain little more than dim, fuzzy spots of light in even the most powerful telescope. One can still infer enough about Uranus and Neptune from telescopic observations to know that they have similar physical properties. The size, mass, composition and rotation of Uranus and Neptune are in fact so similar that they are often called planetary twins.

3. Because uranus and Neptune are so similar in mass, diameter, and rotation rate that they are often called "twin planets." Their axial tilts, however, are very different. Neptune's is similar to the Earth's, but Uranus's is so greatly tilted that its pole lies almost in its orbital plane.
