What is Jupiter? Gas, or liquid, or rock?

To determine the correct answer for question 5, we can analyze the characteristics of the outer planets. The outer planets, also known as gas giants, include Jupiter, Saturn, Uranus, and Neptune. These planets are not small and rocky like the inner planets (Mercury, Venus, Earth, and Mars). Instead, they are primarily composed of gases such as hydrogen and helium. Additionally, they have thick atmospheres and lack a solid surface. Therefore, the statement that the outer planets are small, rocky planets with iron cores is false.
To find the correct answer for question 6, we can consider the formation of the sun. The prevailing scientific theory is that the sun and other stars form from the collapse of giant molecular clouds, which contain gas and dust. These clouds can give rise to multiple stars, forming star clusters. Therefore, it is likely that the sun formed within a cluster of stars similar to itself. Hence, the statement that it is unlikely the sun formed alone and probably formed with a cluster of stars like the sun is true.
Therefore, the correct answers are:
5. False
6. True
i think its
false
true
