Why are there four seasons in a year?

Answer 1

Aseason is one of the major divisions of the year, generally based on yearly periodic changes in weather. Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant. During June, July, and August; the northern hemisphere is exposed to more direct sunlight because the northern hemisphere faces the sun. The same is true of the southern hemisphere in December, January, and February. Contrary to what some people believe, the seasons do not result from the varying distance between the Earth and the Sun. Instead the tilt of the Earth causes the Sun to be higher in the sky during the summer months which increases the solar flux. In temperate and polar regions generally four seasons are recognized: spring, summer, autumn, winter. In some tropical and subtropical regions it is more common to speak of the rainy (or wet, or monsoon) season versus the dry season, because the amount of precipitation may vary more dramatically than the average temperature. For example, in Nicaragua, the dry season is called Summer(Nov to Apr) and the rainy season is called Winter(May to Oct) even though it is located in the northern hemisphere. In other tropical areas a three-way division into hot, rainy and cool season is used. In some parts of the world, special "seasons" are loosely defined based upon important events such as a hurricane season, tornado season or a wildfire season.
