DIFFERENCES BETWEEN ROCKY AND GASEOUS PLANETS
SURFACE
GASEOUS PLANETS
1. SURFACE
Rocky Planets
SOLID SURFACE
They are rocky, mountainous planets, also known as terrestrial planets, they have a solid surface.
They are gas giants and therefore lack an Earth-like surface. If you have a solid inner core, it is likely only the size of Earth.
2. - ATMOSPHERE
2. ATMOSPHERE
GASEOUS PLANETS
Mercury: oxygen (O2), sodium (Na), hydrogen (H2), helium (He) and potassium (K).
Venus - Shrouded in thick, toxic clouds of sulfuric acid.
Earth: 78 percent nitrogen, 21 percent oxygen, and 1 percent other ingredients
Mars: carbon dioxide (CO 2), argon (Ar), nitrogen (N 2), and a small amount of oxygen and water vapor.
They are composed of molecular hydrogen and atomic helium.
3. RINGS
GASEOUS PLANETS
WITHOUT RING
They do not have rings around because they don't have a lot of moons.
They have rings where their moons are.
4. MOON
GASEOUS PLANETS
4. MOON
Do not own or have few.
Mercury and Venus don't have moons.
Earth has a moon.
Mars has two moons
They have a large number of moons.
Jupiter 79
Saturn 82
Uranus 27
Neptune 14
5. SIZE AND DENSITY
GASEOUS PLANETS
5. SIZE AND DENSITY
Near the sun the ice sublimates due to the high temperature, the only elements capable of existing in solid form are the densest and whose sizes remain small.
Far from the sun, the temperature is so cold that the ice does not sublimate, being the perfect setting for the formation of large, low-density gaseous bodies (ice is less dense than heavy elements such as silicon, iron, etc.).
