the earth is one
Earth's atmosphere is mostly made up of nitrogen and oxygen; but the planet itself is more than just its atmosphere - overall Earth, like other terrestrial planets, is mostly made from rock (silicates) with a nickel-iron core. (By comparison, overall the outer gas planets are mostly made from hydrogen and helium.) By relative abundance, oxygen is also the most common element in the Earth's crust.
Most planets have a solid surface, an atmosphere, and orbit a star. They also vary in size, composition, and distance from their star.
Most planets that have so far been discovered have had gaseous atmospheres.
Venus has the most clouds among the terrestrial planets. Its thick atmosphere is composed mostly of carbon dioxide with clouds primarily made of sulfuric acid droplets. These clouds contribute to Venus having a permanent overcast sky.
The atmosphere of the gas giants is usually made up of mostly of hydrogen and what?
As with all planets it is an oblate spheroid
Most planets are made of some kind of terrain and atmosphere. Most planets in our solar system have a terrain that consists of some kind of rock, ice, sand, or dirt that forms the planet and an atmosphere that consists of a gas.
Most planets have atmospheres, the only one in our solar system with no atmosphere is Mercury. The outer, gas giants: Jupiter, Saturn, Uranus, Neptune are mostly gas so they are almost all "atmosphere"
Most planets have an atmosphere, in addition to active comets and Saturn's moon Titan.
most planets look different from different minerals in soil different particles in the atmosphere
the lack of oxygen, and h2o in the atmosphere.
The atmosphere is mostly nitrogen. The atmosphere is above most of the water on Earth.
