How do outer planets differ from inner planets?
Responses
They are smaller than the inner planets.
They consist of a mixture of gases and liquid.
They have very large solid surfaces.
They are not different from inner planets.
The correct response is: They consist of a mixture of gases and liquid.
Outer planets differ from inner planets in several ways.
1. Size: Outer planets are generally much larger in size compared to inner planets. Inner planets, such as Mercury, Venus, Earth, and Mars, are relatively small and compact, while outer planets, such as Jupiter, Saturn, Uranus, and Neptune, are significantly larger in size.
2. Composition: Outer planets consist mainly of gases and liquids. They are classified as gas giants or ice giants due to their primarily gaseous composition. They have thick atmospheres composed of hydrogen, helium, and other gases, along with potential layers of water, ammonia, and methane. In contrast, inner planets have solid surfaces, which are made up of rocks and metals.
3. Solid Surfaces: Unlike inner planets, outer planets do not have clearly defined solid surfaces. Instead, their atmospheres extend for thousands of kilometers and gradually transition into denser layers. The materials within the outer planets are compressed into states of high pressure and are thought to exist as a dense core at their center.
Therefore, outer planets differ significantly from inner planets in terms of their size, composition, and lack of solid surfaces.
Outer planets differ from inner planets in several ways. First, outer planets are larger in size compared to inner planets. They consist of gas giants like Jupiter and Saturn, as well as ice giants like Uranus and Neptune. In contrast, inner planets are smaller and predominantly made up of solid surfaces.
Second, outer planets have thick atmospheres made up of a mixture of gases and liquids. These atmospheres are composed mainly of hydrogen and helium, along with traces of other elements. Inner planets, on the other hand, have thinner atmospheres that are often made up of gases such as nitrogen, oxygen, and carbon dioxide.
Third, outer planets do not have solid surfaces like inner planets. Instead, they have a core made up of rock and metal, which is surrounded by layers of gas and liquid. In contrast, inner planets have solid and rocky surfaces, with some having atmospheres and others being completely airless, like the Moon.
Therefore, the statement "They are not different from inner planets" is incorrect. Outer planets differ from inner planets in terms of size, composition, and the presence of solid surfaces.
