why do the northern and southern hemispheres experience opposite seasons

Throughout the course of the, most places on Earth goes through four noticeable
: summer, autumn (fall), winter and spring, each lasting for about 3 months. The seasons experienced by the northern and southern hemisphere always differ by six months when it is summer in the northern hemisphere, it is winter in the southern hemisphere, and so on. Seasons are a direct consequence of the Earth s tilted rotation, which makes an of about 23. 5 degrees to a line drawn perpendicular to the plane of the. The direction of the Earth s axis stays nearly fixed throughout one, so that at different parts of the orbit one hemisphere leans towards the (summer), while the other leans away (winter). Six months later, the Earth is leaning in the opposite direction. For locations north or south of the, the main feature accompanying each season is a change in temperature caused by the varying amount of sunlight that falls on each hemisphere of the Earth throughout its annual orbit.


The hemisphere tilted towards the Sun will experience longer hours of sunlight, and more direct sunlight. As the Sun is higher in the sky during summer, the sunlight reaching the surface is more concentrated. In winter, the Sun is lower in the sky, and sunlight is spread out over a larger. During spring and autumn, both hemispheres receive about the same amount of sunlight. At the equator, the temperature variation is much smaller throughout the year, and it is common to consider just two seasons: dry and wet (or monsoon). For observers right at the north pole and the south pole, there are only two seasons an almost six-month long winter night followed by an almost six-month long summer! Within the and the (latitudes 66. 5 degrees north and south), there will be at least one polar day (24 hours of continuous daylight, sometime called the midnight sun ) and one polar night (24 continuous hours of darkness).


The date of the start of the seasons is often chosen to start on the dates of the solstices (summer and winter) and equinoxes (autumn and spring). Alternatively, the start of a new season may be associated with the first day of the month (December, March, June and September) in which a or equinox occurs. The Earth s changing from the Sun due to the Earth s orbit is sometimes thought to cause the seasons. This is incorrect! The Earth s distance from the Sun varies by about 3% from closest ( distance = 147. 09 million km) to furthest approach ( distance = 152. 10 million km). This small change in distance cannot account for the temperature differences between summer and winter, and cannot explain how it can be winter in one hemisphere and summer in the other hemisphere.


The Northern and Southern hemispheres of Earth have an opposite cycle of seasons. For example, when the Northern Hemisphere is experiencing summer, the Southern Hemisphere is enjoying the winter. Seasons take place due to the tilt of Earth's axis of rotation (an imaginary line passing through the north and south poles). In essence, whatever hemisphere is tilted towards the sun has more sunlight hours and thus warmer weather. P Based on the attached illustration, here is the listing of seasons: The tilt of the hemisphere decides what season there is in that particular hemisphere. For example, in case (9), the Northern Hemisphere is tilted more towards the sun and hence gets longer sunlight hours and thus has the summer season. In comparison, the Southern Hemisphere is tilted away from the sun at that time and gets less sunlight and hence experiences winter. Hope this helps. P
