Detailed explanation-1: -As Earth orbits the Sun, its tilted axis always points in the same direction. So, throughout the year, different parts of Earth get the Sun’s direct rays.
Detailed explanation-2: -At the time of the formation of the solar system, all the early forming planets were bombarded with stray material. An asteroid-sized like Mars struck the young earth when it was still forming. In the aftermath, this is how the moon formed and the earth got its axial tilt.
Detailed explanation-3: -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.
