Seasons Overview
- Each hemisphere experiences opposite seasons; summer in the north corresponds to winter in the south.
- Key dates demarcate the seasons, influencing climate and daylight hours.
Northern Hemisphere Seasons
- Summer: June 21st marks the longest daylight hours.
- Winter Solstice: December 21st is the first day of winter, with the shortest daylight.
- Spring/Vernal Equinox: March 20th, equal day and night hours.
- Fall/Autumnal Equinox: September 22nd, also equal day and night hours.
Southern Hemisphere Seasons
- Summer: December 21st has the most daylight hours.
- Winter Solstice: June 21st marks the shortest daylight hours.
- Spring: Starts on September 22nd, coinciding with the autumn equinox in the north.
- Fall: Corresponds to northern hemisphere spring, from March 1st to May 31st.
Equinoxes and Solstices
- Equinoxes: Occur when day and night are equal; significant dates are March 20th and September 22nd for both hemispheres.
- Solstices: June 21st (summer) and December 21st (winter) indicate the extremes of daylight hours.
Earth Dynamics
- Orbit/Revolution: Earth takes 365.25 days to complete its revolution around the sun.
- Axis: An imaginary line around which Earth rotates, creating day and night.
- Equator: An imaginary line that divides the Earth into northern and southern hemispheres.
Other Key Concepts
- Daytime: Represented by the lit portions of a seasonal diagram.
- Nighttime: Shaded areas signify periods of darkness.
- Leap Year: Occurs every four years, adding an extra day to maintain calendar accuracy.
Seasonal Duration
