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 axis of rotation of the Earth is tilted at an angle of 23.5 degrees away from vertical, perpendicular to the plane of our planet’s orbit around the sun. The tilt of the Earth’s axis is important, in that it governs the warming strength of the sun’s energy.
Detailed explanation-3: -More tilt means more severe seasons-warmer summers and colder winters; less tilt means less severe seasons-cooler summers and milder winters. It’s the cool summers that are thought to allow snow and ice to last from year-to-year in high latitudes, eventually building up into massive ice sheets.
Detailed explanation-4: -Earth revolves around an enormous source of energy: the Sun. It orbits the Sun every 365 and one-quarter days. It spins on an axis that is tilted 23 and a half degrees to the plane of its orbit. This axial tilt remains steady throughout the year.
