Detailed explanation-1: -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.
Detailed explanation-2: -The tilt of the Earth’s axis as it rotates and orbits around the sun causes these changes in daylight hours through the seasons.
Detailed explanation-3: -The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth’s axis points towards the sun, it is summer for that hemisphere. When the earth’s axis points away, winter can be expected.
Detailed explanation-4: -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.
