πŸ“š Quick Study Guide

  • 🌍 Earth's Orbit: Earth follows an elliptical path around the Sun. This means its distance from the Sun varies throughout the year.
  • πŸ—“οΈ Earth's Axial Tilt: Earth is tilted on its axis at approximately 23.5 degrees. This tilt is the primary reason we have seasons.
  • β˜€οΈ Seasons: Seasons are caused by the varying amounts of sunlight that different parts of Earth receive as it orbits the Sun.
  • 🌑️ Solstices and Equinoxes:
    • β˜€οΈ Summer Solstice: Marks the longest day of the year in the Northern Hemisphere (around June 21st).
    • ❄️ Winter Solstice: Marks the shortest day of the year in the Northern Hemisphere (around December 21st).
    • πŸ‚ Autumnal Equinox: Day and night are approximately equal in length (around September 22nd).
    • 🌱 Vernal Equinox: Day and night are approximately equal in length (around March 20th).
  • πŸ“ Angle of Incidence: The angle at which sunlight strikes Earth's surface. A more direct angle (closer to 90 degrees) results in more concentrated energy and warmer temperatures.
  • β˜€οΈ Perihelion and Aphelion:
    • πŸ’« Perihelion: The point in Earth's orbit when it is closest to the Sun (around January 3rd).
    • 🌌 Aphelion: The point in Earth's orbit when it is farthest from the Sun (around July 4th).
