Mercury, Venus, Earth and Mars the four planets closest to the Sun. They all have rocky crusts and dense mantles and cores.
Terrestrial Planet
200
Jupiter, Saturn, Uranus and Neptune. Made mainly of hydrogen, helium and other gases.
Gas Giant

which terrestrial planets is call the "sister planet" to Earth? Why?
Venus is sometimes called Earth's twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets.

Hydrogen and Helium!

meteor
500
A wide flat zone of small particles that orbit a planet. All four gas giants have these around their equators.
Planetary Rings
500
Explain why the terrestrial planets do not have hydrogen and helium in their atmospheres but do have carbon dioxide.
Carbon dioxide is a heavy gas, helium and hydrogen are light gases. the terrestrial planets do not have a strong enough gravitational pull to hold on to the lighter gases.
500
On saturn there are dark and light colored banding. What do the dark and light colored banding represent?
Dark banding= gases/materials sinking Light banding= gases/materials rising
