Earth's axial tilt is responsible for the four seasons that occur during the year. When a hemisphere is tilted towards the sun, that region receives more sunlight and becomes warmer, while the hemisphere that is tilted away receives less solar energy and is cooler. Keep Learning.
Earth view from Apollo 11. Have you ever why the Earth is tilted instead of just perpendicular with its plane of orbit. Scientists have taken a crack at answering that question.The main consensus is that it has to do with Earthâs formation along with the rest of the planets in the Solar system.ll the same the Earthâs tilt is very important. It is perfectly positioned so that it gives us the seasons and on top of that the seasons are near perfectly calibrated for life. When compared with other planets Earthâs tilt allows for season that are not two extreme in temperature but are pretty well balanced.
