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.
How are the inner planets different 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 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 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 is true about the inner planets?
Of course, the inner planets have shorter orbits around the Sun, and they all spin more slowly. Geologically, the inner planets are all made of cooled igneous rock with iron cores, and all have been geologically active, at least early in their history. None of the inner planets has rings.
What are 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 of the following describes the four inner planets?
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 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.
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 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 not a characteristic of 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.
Which of the following is an inner planet?
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.

Which of the following is a characteristic of all planets?
It says a planet must do three things: It must orbit a star (in our cosmic neighborhood, the Sun). It must be big enough to have enough gravity to force it into a spherical shape. It must be big enough that its gravity cleared away any other objects of a similar size near its orbit around the Sun.
How are inner planets different from 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.
Why are inner planets rocky?
The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K.
