3 answers

During the time it takes for the Earth to complete one revolution around the Sun, several significant phenomena occur, including:

  1. Four Seasons Occur on Earth: The tilt of the Earth's axis relative to its orbit around the Sun causes the changing seasons. As the Earth orbits, different parts of it receive varying amounts of sunlight throughout the year, leading to the four seasons: spring, summer, autumn, and winter.

  2. Earth Experiences a Complete Day: The rotation of the Earth on its axis takes approximately 24 hours, which defines the length of a day. Therefore, during one complete revolution around the Sun, the Earth experiences many full days and nights.

  3. Day Turns to Night: As the Earth rotates on its axis, different parts of the planet are illuminated by the Sun, resulting in daytime, while the parts facing away from the Sun experience nighttime. This cycle occurs continuously, independent of the Earth's revolution around the Sun.

  4. The Moon Makes One Complete Phase Change: While it does not take exactly one revolution of the Earth around the Sun for the Moon to complete its phases, it is worth noting that the Moon completes its lunar phases approximately every 29.5 days. During the year, the Moon will go through its complete cycle of phases multiple times.

In summary, while the Earth revolves around the Sun, the four seasons change, multiple days and nights occur, and the Moon undergoes several phase changes. However, the Moon does not complete a full phase cycle in precisely one year, but it does experience several during that time.

The most accurate and comprehensive answer from your options regarding what happens during the Earth's complete revolution around the Sun is:

Four seasons occur on Earth.

This encapsulates the main result of the Earth's orbit in relation to its axial tilt and sunlight exposure.
