What part of the earth is affected by the moon?

The entire earth is affected by the moon. The earth is influenced in several ways by the moon, the most important being: - Attraction between masses; - Reflection of light. - The attraction between the earth and the moon has a direct influence on earth's water resulting in the tides; - This attraction also result in small oscillations on the otherwise ecliptic path around the sun. The center of gravity of the earth and its moon combined follows this 'perfect' ecliptic path; - Finally, the reflection of the sun on the moon influences the amount of natural light available - essentially at night.
