What else can I help you with?
What are the two main gases found in the outer planets?
helium and hydroen
What are the two main gases that make up the inner and outer planets?
Hydrogen and Helium.
What are the main gases present in each planet?
Most planets' atmospheres are carbon dioxide, but that varies depending upon many factors.
What are the two main reason why Jovian planets have much thicker atmoshperes than the Terrestrial planets?
While terrestrial planets are made of rock and have gases in the atmosphere, jovian planets are made almost entirly of gases. If an atmosphere is made of gases in a planet, then the atmosphere of the planets with more gases will be thicker.
What is the main difference between the inner planets and the outer planets?
The inner planets are smaller, and do not have the dense atmospheres of the outer planets. The four inner planets (Mercury, Venus, Earth, and Mars) have warmer temperatures than the exteriors of the outer planets (Jupiter, Saturn, Uranus, and Neptune).The "gas giants" have very hot lower atmospheres, caused by the intense pressure. The atmospheres are mostly hydrogen, but for Uranus and Neptune there are higher levels of water, methane, and ammonia. All of the gas giants have multiple moons and rings, the most visible being the ice rings around Saturn.they are divided by inner and outer and the outer planet are the planets that have bigger planets.
What is the main reason you could not land on outer planets er planets?
The outer planets are gas planets
What is the main difference between inner planets and outer ones?
Inner planets are mostly rock and outer planets are mostly gas.
What splits the outer planets from the inner planets?
The main Asteroid Belt.
The main element element in the atmospheres?
Nitrogen at 78%. Oxygen at 21%. and other gases at 1%
How do the planets in the two groups different?
The first 4 planets, Mercury, Venus, Earth, and Mars, are called rock planets, and the last 4, Jupiter, Saturn, Uranus, and Neptune, are the gas planets. The main differences between these two groups are that the rock planets are made of rock, the gas planets are made of gas, the rock planets are typically smaller than the gas planets, and the gas planets have rings.
Which planet has methane as the main gas in its atmosphere?
The giant outer planets Jupiter, Saturn, Uranus, and Neptune have extremely thick atmospheres of hydrogen, helium, methane, and ammonia. Titan, the moon of Saturnalso has a methane-ammonia atmosphere.
Where are the outer planets located?
The outer planets, also known as the gas giants, are located beyond the asteroid belt in our solar system. They include Jupiter, Saturn, Uranus, and Neptune. They are significantly larger than the inner rocky planets and consist mostly of gases and liquids.
