Detailed explanation-1: -As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
Detailed explanation-2: -Earth’s axial tilt is responsible for the formation of seasons. When a hemisphere is tilted towards the sun, that region receives more sunlight and becomes warmer, while the hemisphere that is tilted away receives less solar energy and is cooler.
Detailed explanation-3: -Earth revolves about the Sun, producing the 365-day year.
Detailed explanation-4: -Earth’s axial tilt (also known as the obliquity of the ecliptic) is about 23.5 degrees. Due to this axial tilt, the sun shines on different latitudes at different angles throughout the year. This causes the seasons.
