Concept:Rotation means an object spinning on its own axis, while revolution means an object travelling around another object.
The planets revolve around the sun, so any statement that mixes these two terms is false.
Explanation:The sun gives off heat and light, so its rays provide energy to the whole solar system.
Therefore, option A is a correct statement.
The sun is at the centre of the solar system, and the planets move in fixed orbits around it.
This movement around the sun is known as revolution, not rotation.
Each planet also rotates on its own axis to cause day and night, but no planet rotates round the sun.
Hence, option B is the false statement.
Option C is correct because the planets do revolve around the sun.
Option D is correct because the sun is at the centre of the system.
Answer:The statement that is not true is
B: "all the planets rotate round the sun."
The correct description is that the planets revolve around the sun.
