प्रश्न
Why are there seasons on earth?
उत्तर
The axis of the earth is inclined at an angle of 66 1 °/2 to its orbital plane or 21 1 °/2 between the equator and orbital plane. While earth swings around the Sun. Different parts of its surface are exposed to sunlight for different lengths of time each day. Some regions bask in the warmth of the sunlight while others remain cold. Earth’s tilt while spreading the light over a larger area causes changes in the altitudes of the sun in different latitudes. This causes slow changes in temperature at a place. The changing weather conditions in an annual cycle of revolution is called Season. If the earth did not tilt on its axis there would be no seasons.
