Planets are round because of their orbits.

The correct Answer is:
To determine whether the statement "Planets are round because of their orbits" is true or false, we can break down the reasoning step by step. ### Step-by-Step Solution: 1. **Understanding the Statement**: The statement suggests that the shape of planets (being round) is a result of their orbits. 2. **Identifying the Key Concept**: The shape of planets is primarily influenced by gravitational forces rather than their orbital paths. 3. **Role of Gravity**: Gravity pulls matter towards the center of a planet. As a planet forms, gravity causes it to pull all its mass into a shape that minimizes potential energy, which is a sphere. 4. **Orbital Motion**: While planets do have orbits around stars (like the Earth around the Sun), these orbits do not influence the shape of the planets themselves. Instead, orbits are a result of gravitational interactions between the planet and the star. 5. **Conclusion**: Since the round shape of planets is due to gravity and not their orbits, the statement "Planets are round because of their orbits" is false. ### Final Answer: The statement is **false**. Planets are round because of their gravity, not because of their orbits. ---
