πŸ“š Quick Study Guide

  • 🌍 Earth's Rotation: The Earth rotates on its axis, causing day and night. One rotation takes approximately 24 hours.
  • πŸŒ• Moon's Orbit: The Moon orbits the Earth in an elliptical path. One orbit takes approximately 27.3 days.
  • β˜€οΈ Earth's Orbit: The Earth orbits the Sun in an elliptical path. One orbit takes approximately 365.25 days (one year).
  • πŸŒ— Lunar Phases: The Moon's phases (new moon, first quarter, full moon, last quarter) are due to the changing angles at which we see the Moon's illuminated surface.
  • πŸŒ‘ Eclipses: Solar eclipses occur when the Moon passes between the Sun and Earth, blocking the Sun's light. Lunar eclipses occur when the Earth passes between the Sun and Moon, casting a shadow on the Moon.
  • πŸ“ Tilt of the Earth: The Earth's axis is tilted at approximately 23.5 degrees, causing seasons.
  • πŸ“ Scale Models: When creating models, it's crucial to represent the relative sizes and distances as accurately as possible to understand the true scale of the Earth-Moon-Sun system.
