What are 4 characteristics of the inner planets?
The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings.
What are 3 facts about inner planets?
The inner planets have no rings circling them and zero to a few moons. Earth has one moon, and Mars has two. Mercury and Venus do not have any moons. Mars, Earth and Venus have atmospheres that are able to generate weather.
What are the inner planets known as?
From top: Mercury, Venus, Earth and Mars. The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth's terra firma. The terrestrial planets are the four innermost planets in the solar system.
What is difference between inner and outer planets?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
Which set of characteristics are unique to the inner planets?
Which set of characteristics is unique to the inner planets? The four inner planets have slower orbits slower spin no rings and they are made of rock and metal.
How are the inner planets different than the outer planets?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
What are the characteristics of inner and outer planets?
Summary. The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
What is the inner planets made of?
Every inner planet has a core. The cores of Mercury, Venus, and Earth are composed of iron-nickel. Mars's core is made of liquid iron sulfide mixed with some nickel….Structure.

Which characteristic is common to all inner planets quizlet?
All the inner planets are dense. The inner planets are less dense than the outer planets.
What is not a characteristic of the inner planets?
None of the inner planets have rings, while all of the outer planets have quite a few (rings are made up of small particles, possibly ice, that circle the outer planets). Inner planets have a paucity of moons, with Mars claiming two and Earth just one. Mercury and Venus have none.

How do the inner planets differ from the outer planets?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
What characteristics do the inner planets have in common What is one unique characteristic of each of these planets explain your answer?
Explain your answer. Inner planets are all terrestrial planets consisting mostly of solid rock with metallic cores. They have from zero to two moons each, and their surfaces are marked with impact craters. Mercury is unique because it has a daily temperature range of about 600 °C.
Why are the inner planets different from the outer planets quizlet?
Inner planets are smaller than the outer planets; gas giants have more gravity; Farther apart, inner planets have a solid surface, Inner planets are hotter, inner planets have a shorter period of revolution. Distance from the sun causes these differences. Inner planets have most of their atmospheres burned away by sun.
What is the difference between inner planet and outer planet?
Inner planets are those which are small in size such as Mercury, Venus, Earth and Mars. Earth is the largest inner planet and Mercury is considered to be the smallest inner planet. On the other hand, outer planets are those which are huge in size, for example – Jupiter, Saturn, Uranus and Neptune.
How are the inner and outer planets different from each other?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
What do all of the inner planets have in common quizlet?
All of the inner planets have in common that they all have a solid, rocky surface.
What are the characteristics of inner planets quizlet?
The inner planets are small and dense and have rocky surfaces. What are the characteristics of the inner planets? Mercury: is the smallest terrestrial planet closest to the sun. Venus: has a thick atmosphere, an unusual pattern of rotation, and the hottest surface of any planet.
What are the characteristics that distinguish the inner planets from the outer planets?
The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
What do the inner planets have in common quizlet?
The common features of the inner/terrestrial planets are that they are all relatively small and dense, are warm, have rocky surfaces dented with impact craters, have little to no moons, no rings, and have a crust, mantle, and an iron core. The four inner planets are Mercury, Venus, Earth, and Mars.
What do inner planets have that outer planets don t?
There are a few important observations: 1) The “inner planets” (Mercury, Venus, Earth, Mars) don't have rings and all of the “outer planets” (Jupiter, Saturn, Uranus, and Neptune) do. 2) The outer planets are much more massive than the inner planets.
Why are the inner planets different from the outer planets?
Outer planets are composed of lighter elements such as gases and inner planets are composed of heavy elements such as iron. Inner planets have fewer moons, small, silicate surface, nickel-iron core, higher density and rotate more slowly compared to outer planets.
