- All outer planets are made up of gases and hence called gaseous planets or Jovian planets while inner planets are made up of rocks mostly and hence called terrestrial planets.
- All outer planets rotate faster than the Sun as they are farther away from the Sun and experience the weaker gravitational force of the Sun.

Consider the following statements: 1. All outer planets are made up o...
Explanation:
Statement 1: All outer planets are made up of gases and liquids.
This statement is true. The outer planets in our solar system, also known as the gas giants, are composed primarily of gases and liquids. These planets include Jupiter, Saturn, Uranus, and Neptune. They have a relatively small solid core surrounded by thick atmospheres of hydrogen and helium, with various layers of gases and liquids. The presence of these gases and liquids gives these planets their characteristic appearance and behavior, such as the presence of colorful bands and storms on their surfaces.
Statement 2: All outer planets rotate faster than all inner planets.
This statement is false. The rotation speeds of planets vary, and there is no strict rule that states that all outer planets rotate faster than all inner planets. For example, Venus, which is an inner planet, has a very slow rotation speed, taking about 243 Earth days to complete one rotation. On the other hand, Jupiter, which is an outer planet, has a fast rotation speed, completing one rotation in about 10 hours. Similarly, other outer planets like Saturn, Uranus, and Neptune also have different rotation speeds.
Conclusion:
Based on the above analysis, we can conclude that statement 1 is true, as all outer planets are indeed made up of gases and liquids. However, statement 2 is false, as the rotation speeds of planets are not solely determined by their location (inner or outer) but can vary from planet to planet. Therefore, the correct answer is option 'C' - Both 1 and 2.
