Which of the following statements is true regarding day and night?a)Th...
Explanation:
Day and night occur due to the rotation of the Earth. As the Earth rotates on its axis, different parts of the Earth are exposed to or away from the Sun's light, resulting in the occurrence of day and night.
Rotation of the Earth:
- The Earth rotates on its axis from west to east. This rotation takes approximately 24 hours to complete, resulting in one day and one night cycle.
- As the Earth rotates, the part facing the Sun experiences daylight, while the part facing away from the Sun experiences darkness.
Day and Night:
- When a specific region of the Earth is facing towards the Sun, it experiences daylight, and this period is known as daytime.
- Conversely, when a particular region is facing away from the Sun, it experiences darkness, and this period is known as nighttime.
- Day and night occur simultaneously worldwide, but the specific regions experiencing day and night change as the Earth rotates.
Simultaneous Day and Night:
- Different parts of the Earth experience day and night at the same time.
- For example, when it is daytime in one part of the Earth, it is nighttime in the other part.
- This is because the Earth's rotation allows for simultaneous occurrence of day and night in different regions.
- As the Earth rotates, the regions that were previously in daylight move into darkness, while the regions that were in darkness move into daylight.
Incorrect Statements:
- Option a) "The Sun moves around the Earth" is incorrect. The Earth revolves around the Sun, causing the apparent movement of the Sun across the sky.
- Option b) "Day and night occur simultaneously worldwide" is incorrect. Day and night occur at different times in different parts of the world due to the Earth's rotation.
- Option c) "Day and night occur due to the rotation of the Moon" is incorrect. The Moon does not cause day and night; it only affects the Earth's tides and has no direct impact on the occurrence of day and night.
Therefore, the correct statement is option d) "Different parts of the Earth experience day and night at the same time."

Different parts of the Earth experience day and night at the same time because the rotation of the Earth occurs uniformly. However, the time of day may vary due to time zones.
