Detailed explanation-1: -The greater Earth’s axial tilt angle, the more extreme our seasons are, as each hemisphere receives more solar radiation during its summer, when the hemisphere is tilted toward the Sun, and less during winter, when it is tilted away.
Detailed explanation-2: -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-3: -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-4: -The tilt of the Earth’s axis also defines the length of daylight. Daylight hours are shortest in each hemisphere’s winter. Between summer and winter solstice, the number of daylight hours decreases, and the rate of decrease is larger the higher the latitude. The fewer sunlight hours the colder the nights.
Detailed explanation-5: -Angle of Separation The higher the angle, the more intense the solar radiation. Because of the curvature of the Earth, sunlight strikes the poles at a low angle. Rays striking Earth at a low angle must pass through more atmosphere. Earth’s atmosphere absorbs and reflects solar energy.
