Final answer:
The Moon revolves around the Earth approximately every 27.3 days, causing the Moon's phases while the Earth revolves around the Sun every 365.25 days, resulting in the change of seasons. Both movements are a result of gravitational forces.
Step-by-step explanation:
The relationship between the Earth and Moon, and the Sun and Earth regards their orbits or revolutions around each other. Firstly, the Moon revolves around the Earth approximately every 27.3 days, a movement known as a sidereal month. This revolution is the reason we perceive the Moon's phases.
Similarly, the Earth revolves around the Sun, completing one full orbit approximately every 365.25 days (our year). This revolution leads to variances in sunlight, leading to our seasons. Both of these systems operate based on the gravitational pull between bodies.
