carbon dioxide (CO2)
The four outer gas giants.
There are four planets that are made out of gas: Jupiter, Saturn, Urans and Neptune. These planets are called the "gas giants" . The other four planets (Earth, Mercury, Venus and Mars) are mostly made out of rock.
Venus.
Gas giants are planets whose atmosphere is predominantly composed of gases, such as hydrogen and helium. These planets have a small solid core surrounded by thick layers of gas. Examples of gas giants in our solar system include Jupiter and Saturn.
Venus has a thick atmosphere composed mainly of carbon dioxide with clouds of sulfuric acid.
Venus is made up of an iron core and rocky mantle. While it's atmosphere mostly consists of carbon dioxide and nitrogen.
Venus is primarily composed of rock and metal, with a thick atmosphere made mostly of carbon dioxide, along with clouds of sulfuric acid. It does not have significant bodies of water like Earth; instead, its surface is dry and extremely hot, with temperatures capable of melting lead. Thus, Venus is not made mostly of gas or water, but rather is a rocky planet with a dense gaseous atmosphere.
It's rocky, but it has an atmosphere made up mostly of carbon dioxide and has clouds made of sulfuric acid.
Venus is predominantly made up of rock. Its surface is rocky with mountain ranges, volcanoes, and vast plains. The atmosphere of Venus is composed mainly of carbon dioxide and clouds of sulfuric acid.
No. Venus is made of rock and metal, like Earth.
Venus is made up of an iron core and rocky mantle. While it's atmosphere mostly consists of carbon dioxide and nitrogen.
Rock.Rock.
Carbón dioxide gas
The atmosphere is made mostly of gas because gases have low molecular densities, allowing them to be easily suspended in the Earth's gravity. The gases in the atmosphere help regulate temperature and provide elements essential for life, such as oxygen.
Mostly carbon dioxide (96.5%). Most of the rest is nitrogen.

This is a little like asking 'Why is iron mostly metal?' Atmospheres are made up of gas.
