Examples of seasonal weather changes

📚 Quick Study Guide

• ☀️ Seasons are caused by Earth's tilt: Earth's axis is tilted at approximately 23.5 degrees. This tilt causes different parts of the Earth to receive more direct sunlight at different times of the year.
• 🗓️ Revolution around the Sun: As Earth orbits the sun, different hemispheres are tilted towards the sun, resulting in changing seasons. One full orbit takes approximately 365.25 days, which is why we have leap years.
• 🌡️ Temperature Variations: Seasonal changes are primarily driven by temperature changes. Higher solar intensity leads to warmer temperatures, and vice versa.
• 🌧️ Precipitation Patterns: Seasonal changes also affect precipitation patterns. Some regions experience more rainfall or snowfall during specific seasons.
• 🧭 Equinoxes and Solstices:
  • Equinoxes (Spring and Autumn): The sun shines equally on both hemispheres. Day and night are approximately equal in length.
  • Solstices (Summer and Winter): One hemisphere is tilted most towards the sun (summer) and the other is tilted away (winter).
