Study Notes
Seasons
- Seasons are distinct periods of the year with unique climate conditions, with four seasons being spring, summer, autumn, and winter.
- Seasons significantly influence vegetation and plant growth, with winter having cold weather, limited daylight, and limited plant growth.
- The four-season year is typical only in mid-latitudes, with larger differences in seasons farther north.
- Near the Equator, regions experience little seasonal variation, while pole regions experience significant seasonal variation, with daylight changes dramatically between summer and winter.
How Seasons Occur
- Earth's tilted axis causes the seasons.
- Throughout the year, different parts of Earth receive the Sun's most direct rays.
- When the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
Characteristics of Seasons
- In the Northern Hemisphere, winter generally begins on December 21 or 22, and summer begins on June 20 or 21.
- Spring and autumn begin on equinoxes, days that have equal amounts of daylight and darkness.
- The vernal, or spring, equinox falls on March 20 or 21, and the autumnal equinox is on September 22 or 23.
- The seasons in the Northern Hemisphere are the opposite of those in the Southern Hemisphere.
Earth's Axis and Orbit
- Earth's axis is an invisible line that runs through its center, from pole to pole, and it is tilted relative to the orbital plane.
- Earth rotates around its axis, which is tilted at an angle of about 23.5 degrees.
Variations in Sunlight
- Because of the axial tilt, different parts of the Earth receive varying amounts of sunlight throughout the year.
- When a hemisphere is tilted toward the Sun, it experiences summer. When it is tilted away, it experiences winter.
- The intermediate stages are spring and autumn.
Seasonal Variations by Region
- The four-season year is typical only in mid-latitudes.
- Places near the Equator experience little seasonal variation, with alternating rainy and dry seasons.
- Polar regions experience significant seasonal variation, with daylight changes dramatically between summer and winter.
