During a complete revolution of the Earth around the sun, four seasons occur on Earth. Additionally, Earth experiences a complete day and the moon makes one complete phase change. Day also turns to night during this time.
To determine what happens during a complete revolution of the Earth around the sun, we need to understand the concept of a year and the Earth's movement.
The Earth takes approximately 365.25 days to complete one revolution around the sun, which is called a year. During this time, several things happen:
1. Four seasons occur on Earth: As the Earth orbits the sun, its axis is tilted, causing different parts of the Earth to receive varying amounts of sunlight throughout the year. This variation in sunlight leads to the changing of seasons, including spring, summer, autumn, and winter.
2. Earth experiences a complete day: The Earth rotates on its axis, which takes approximately 24 hours, resulting in a complete day. As the Earth orbits the sun, different parts of the planet are exposed to sunlight, leading to day and night.
3. The moon makes one complete phase change: While the Earth is orbiting the sun, the moon continues to orbit the Earth. The moon's phases, which range from new moon to full moon and back to new moon, occur roughly every 29.5 days. So, during a complete revolution of the Earth around the sun, the moon would go through approximately 12-13 phase changes.
4. Day turns to night: As the Earth orbits the sun, the rotation of the planet causes day and night to alternate. When a specific part of the Earth is facing the sun, it experiences daylight, while the opposite side experiences darkness and nighttime.
Therefore, during a complete revolution of the Earth around the sun, all of these events occur: Four seasons, a complete day-night cycle, multiple phase changes of the moon, and the transition between day and night.
