explain the phenomenon of seasons
Answers
Answer:
The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the "ecliptic plane" (the imaginary surface formed by it's almost-cicular path around the sun).
Explanation:
The cycle of seasons is caused by Earth's tilt toward the sun. The planet rotates around an (invisible) axis. At different times during the year, the northern or southern axis is closer to the sun.
Answer:
The phenomenon of the seasons
Contrary to popular belief, the phenomenon of the seasons – or the periodic change of climate over the months – is not a result of Earth approaching or moving away from the Sun. Seasonal climatic variations are due to the slight tilt of the Earth, which spins like a top tilted at an angle of 23.5 degrees in relation to its orbital path. This tilt explains why one hemisphere receives more sun than the other at a given time of year. If the Earth’s axis were not tilted, there would be no seasonal variations in temperature. Our climate in October would more or less resemble our climate in March.

Spring equinox
On March 20 or 21, day and night are of equal duration in the Northern hemisphere, which is why it is referred to as the spring equinox. On that day, the Sun rises exactly in the east and sets exactly in the west.
Summer solstice
In summer in the Northern hemisphere, the Sun is high in the sky and it is hot. The summer solstice, which occurs on June 21, is the longest day of the year.
Autumnal equinox
On September 22 or 23, day and night are of equal duration in the Northern hemisphere, which is why it is referred to as the autumnal equinox. On that day, the Sun rises exactly in the east and sets exactly in the west.
Winter solstice
In winter in the Northern hemisphere, the Sun is low in the sky and it is cold. The winter solstice, which occurs on December 21 or 22, is the shortest day.
