Final answer:
A change in the sun's pull of gravity would affect Earth's orbit.
Step-by-step explanation:
A change in the sun's pull of gravity would affect Earth's orbit. The gravitational force exerted by the sun keeps the Earth in its orbit. If there is a change in the sun's pull of gravity, it would alter the force acting on Earth, potentially leading to a change in its orbit.
For example, if the sun's pull of gravity increased, Earth would experience a stronger gravitational force. This could cause Earth to be pulled closer to the sun, resulting in a smaller orbit. On the other hand, if the sun's pull of gravity decreased, the gravitational force acting on Earth would weaken, potentially leading to a larger orbit.
