|
Earth’s tilt has no measurable effect on its seasons.

The tilt of the Earth causes equinoxes on December 21 and June 21.

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: -As Earth rotates, the Sun’s appears higher in the sky, and the shadows get shorter. At noon, with the Sun overhead, objects cast short shadows or no shadow at all. As Earth continues to rotate and the Sun appears lower in the sky toward evening, the shadows get longer again.
Detailed explanation-3: -The first major contributor to the Sun’s apparent motion is the fact that Earth orbits the Sun while tilted on its axis. The Earth’s axial tilt of approximately 23.5° ensures that observers at different locations will see the Sun reach higher-or-lower positions above the horizon throughout the year.
Detailed explanation-4: -The tilt of Earth’s axis relative to its orbit around the sun results in predictable changes in the duration of daylight and the amount of sunlight received at any latitude throughout a year. These changes cause the annual cycle of seasons and associated temperature changes.
