Which 2 inner planets have thick atmospheres?
There are four inner planets, which starting with the closest to the sun are Mercury, Venus, Earth, and Mars. Of these, Venus and Earth have thick atmospheres, whereas Mercury and Mars don't.
How are planets closest to the sun different from the planets that are farther away?
The planets that are closest to the sun get more heat than the ones more farther away. The four inner planets are dense and rocky. The four other planets have small solid cores surrounded by vast atmospheres. The four inner planets have one significant satellite among them (the moon), while each of the outer planets has many satellites. The four inner planets are small, while the outer planets are massive.
What are the 3 features that the outer planets have in common?
These are the four outer gas giant planets; Jupiter, Saturn, Uranus and Neptune. They are all much larger than the inner planets, they all have a similar composition (gaseous atmospheres, mainly of Hydrogen and Helium) and they each have many moons and a ring system. None of the inner planets have a ring system and there are only three moons in total for the four inner planets (one for Earth and two in orbit around Mars).
What is the outermost terrestrial planet?
Of the four inner terrestrial planets, Mars is the furthest from the sun. This is the outermost of the four inner planets.
What are 3 ways inner planets are alike?
The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. The inner planets all have a clear solid surface, unlike gaseous planets. The inner planets do not have a ring system. The inner planets are of similar densities.
What are the atmospheres of the four inner planets?
all have 1 moon
Do inner planets have atmospheres?
Yes, all four do, except for Mercury.
How do the sizes of the four inner planets compare?
they are small

What describes the four inner planets?
Rockey and hotter .1. These planets have gaseous atmospheres.2. The inner planets all have one moon each.3. These terrestrial planets have surfaces that are rocky hard.4. The inner planets were formed differently than the outer planets.Those are the choices.. Thankks for your help, if you decide to help.
Why are the four closest planets to the sun are of terrestrial nature and the last four are of gaseous-icy nature?
The gas giants and the terrestrial planets initially formed in similar ways, however, the powerful solar wind of the young sun stripped away the first atmospheres of the inner planets. The outer planets were less affected by this and so retained their thick atmospheres of hydrogen and helium. Today, the outer planets recieve much less heat from the sun than do the inner planets, allowing various ices to form.
Which inner planets have rings?
None of the four inner planets have inner rings, while each of the four outer gas planets have a ring system.

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 are the similarities of the four inner planet's atmospheres?
all have 1 moon
Do any inner planets have rings?
No. None of the inner four planets have rings.
