What Are The Most Significant Changes To The Tilt

Since the seasons are caused by the tilt of the Earth's axis, any change to the tilt will have a significant impact in the seasons. If the tilt was in the opposite direction, the northern hemisphere will have winter and summer when the southern hemisphere had them, and the southern hemisphere will have winter and summer when the northern hemisphere had them. The vernal and autumnal equinox will be opposite as well. If the tilt of the earth's axis had no tilt(straight up and down), every hemisphere would remain in the same season it's in all year around. That means that every place that is being hit by indirect sunlight will remain winter all year, and every place that is being hit by direct sunlight will remain summer all year, etc.

The earth's seasons mainly depend on the tilt of …show more content…
During the summer, the sun hits at less of an angle, which makes the days hotter and longer. On the contrary, the sun hits at a greater angle during the winter, making days shorter and colder. If the angle of the sunlight becomes more direct(less angle), at a certain time, the summer solstice will come sooner, the first day of spring might also come sooner. If the angle of the sunlight hits at a much greater angle, the winter solstice will come sooner, as well as the first day of fall.

The earth's tilt and the angle that the sun hits the earth work together to make the seasons. During the summer the sun hits the earth more directly, and during the winter the sun hits the earth more indirectly. The reason why direct or indirect light causes the seasons is because the light of the sun is more concentrated when it's direct, but when it hits indirectly it's more spread out. Therefore, if the angle of the sun changes and hits more directly to a certain place on earth it will most likely be warmer (summer), and if changes to an indirect angle, that place will most likely be colder
