Detailed explanation-1: -The tilt of the Earth’s axis is the most important reason why seasons occur. The Earth’s movement around the Sun causes seasons. The Earth is always tilted to one side as it orbits the Sun. So, when the North pole tilts towards Sun, it’s summer in the Northern hemisphere and winter in the Southern hemisphere.
Detailed explanation-2: -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. Seasons are caused by Earth’s axial tilt and temperatures and nature’s processes are affected.
Detailed explanation-3: -Earth’s axis is currently tilted 23.4 degrees, or about half way between its extremes, and this angle is very slowly decreasing in a cycle that spans about 41, 000 years. It was last at its maximum tilt about 10, 700 years ago and will reach its minimum tilt about 9, 800 years from now.
