The correct Answer is:
To solve the question, "The four planets in the outer system are made of rock and metal," we need to analyze the characteristics of the planets in both the inner and outer solar systems. ### Step-by-Step Solution: 1. **Identify the Inner and Outer Planets**: - The solar system is divided into two main groups of planets: the inner planets and the outer planets. - The inner planets are Mercury, Venus, Earth, and Mars. - The outer planets are Jupiter, Saturn, Uranus, and Neptune. 2. **Composition of Inner Planets**: - The inner planets (Mercury, Venus, Earth, Mars) are primarily composed of rock and metal. - They are smaller in size compared to the outer planets and have solid surfaces. 3. **Composition of Outer Planets**: - The outer planets (Jupiter, Saturn, Uranus, Neptune) are primarily composed of gases. - They are much larger than the inner planets and are often referred to as "Gas Giants." - Jupiter and Saturn are mainly made of hydrogen and helium, while Uranus and Neptune have more ices in their composition. 4. **Conclusion**: - The statement "The four planets in the outer system are made of rock and metal" is false. - The correct information is that the four planets in the outer solar system are primarily made of gases, not rock and metal. ### Final Answer: The statement is false. The four planets in the outer solar system (Jupiter, Saturn, Uranus, and Neptune) are not made of rock and metal; they are mostly composed of gases. ---
