No, the seasons are due to the wobble in Earth's spin - axis of rotation of the earth is about 13 degrees off the perpendicular to Earth's revolving around the sun. when the top of the earth points towards the sun we have summer (and the southern hemisphere has winter. As the earth progresses on its trip around the sun so also do we progress through the seasons (from solstice to equinox to solstice to equinox and we have a year)
