The Moon’s Influence on Earth:
- Tides: The moon’s gravitational pull creates bulges in Earth’s Oceans, resulting in high and low tides.
- Earth’s Rotation: The moon’s gravitational influence has slowed down Earth’s rotation over time, increasing the length of our day.
- Stability of Earth’s Axis: The moon’s gravitational pull helps stabilize Earth’s axial tilt, contributing to the stability of our seasons.
The Moon’s Geological history:
- Early Bombardment: The moon’s surface bears the scars of intense bombardment by asteroids and comets during its early formation.
- Volcanic Activity: Early in its history, the moon experienced significant volcanic activity, creating vast plains of solidified lava known as maria.
- Impact Craters: The moon’s surface is pockmarked with impact craters, ranging in size from tiny pits to massive basins.
A Journey to the Moon: From Myth to Reality
The moon has been a source of inspiration and wonder for humanity since the dawn of civilization. Ancient cultures across the globe developed myths and legends about the moon, attributing its phases and eclipses to deities and celestial beings.
Table 2: Lunar Myths and Legends
| Culture | Myth | Description |
