Feb 11, 2022 · Seasons are periods of the year with distinct weather conditions and day lengths. Earth's four seasons are spring, summer, autumn (fall) and winter.

Sep 22, 2023 · Tomorrow’s September equinox signals the change of season, from summer to fall in the Northern Hemisphere and from winter to spring in the Southern Hemisphere. But why do Earth’s seasons change?...

Mar 17, 2025 · Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Seasons are caused by the fact that the Earth is tilted on its axis by 23.5°. The tilt's orientation with respect to space does not change during the year; thus, the Northern Hemisphere is tilted toward the sun in June and away from the sun in December, as illustrated in the graphic below.

Seasons happen because Earth's axis is tilted at an angle of about 23.4 degrees and different parts of Earth receive more solar energy than others. Earth's orbit around the Sun is elliptical. …

Dec 9, 2024 · The four seasons— spring, summer, fall, and winter —follow one another regularly. Each has its own light, temperature, and weather patterns that repeat yearly.

Nov 22, 2019 · Four seasons -- autumn, winter, spring and summer -- occur throughout the year. Each hemisphere experiences an opposite season. For example, the winter season in the northern hemisphere is summer in the southern hemisphere. The seasons are caused by the tilt of the Earth's axis as it orbits the sun.

Feb 18, 2025 · The four seasons—spring, summer, fall (or autumn), and winter—are the distinct periods of the year characterized by recurring patterns of weather, temperature, and daylight hours.

Mar 14, 2024 · The Earth’s four seasons are a complex yet elegant consequence of our planet’s axial tilt and its orbit around the Sun. Understanding that it is the tilt, rather than the distance to the sun, that drives these changes is vital for comprehending Earth’s climate patterns.

Many folks assume the four seasons happen because the Earth is closer to the Sun in the summer (so it’s hotter) and then farther from the Sun in the winter (so it’s colder). This is incorrect. Learn what causes the seasons.
