How long does a full revolution of the Earth around the Sun take?

• A. 24 hours
• B. 30 days
• C. 365 days
• D. 12 months

Answer: (C)

The duration it takes for the Earth to complete one full revolution around the Sun is known as a year, which is approximately 365 days. This orbital period is the basis for the calendar year we use, and it accounts for the time it takes for the Earth to travel along its elliptical orbit. This period is defined by the Earth's movement in relation to the position of the Sun, leading to the seasonal changes we experience throughout the year. The 365 days figure represents a solar year, and while this value is averaged, it is the most commonly accepted time frame for the Earth's revolution around the Sun. In context, the 24 hours mentioned is the time it takes for the Earth to rotate once on its axis, defining a day. The 30 days option may suggest the lunar cycle, which is separate from the Earth's annual revolution. Lastly, while 12 months typically aligns with a calendar year, it is important to note that this format (12 months) is merely a human-made division of the 365-day year and does not accurately represent the full revolution itself. Thus, the correct answer is clearly understood to be 365 days.
