When it is summer in the Northern Hemisphere which season does the Southern Hemisphere experience?

Answer

Verified

Hint:> When the northern hemisphere has spring, the southern hemisphere experiences autumn.> As the duration of day increases in the northern hemisphere, the duration of the day decreases in the southern hemisphere.

Complete answer:

No matter what time of the year it is, the northern and the southern hemisphere will always experience a season opposite to the other. Therefore, if the northern hemisphere has the summer season, then the southern hemisphere will experience the winter season. When we say opposite we also mean that when it is spring season in the northern hemisphere, then it is autumn season in the southern hemisphere.The main reason for this phenomenon is the tilt of the earth on its axis. With respect to its orbital plane, the earth is tilted at an angle of 23.4 degrees. Since the earth is tilted slightly, one of the hemispheres will always receive more and direct rays from the sun. It means that when the earth is tilted towards the sun, then the northern hemisphere receives direct sun rays which are experienced by us as the summer season. During this time the southern hemisphere experiences the winter season. This phenomenon keeps alternating as the planet revolves around the sun. This summer season lasts for half a year, or rather half a revolution.In the second half of the revolution, the earth tilts away from the sun, thus exposing the southern hemisphere to the direct sun rays. This is the time when the northern hemisphere is experiencing winter season, the southern hemisphere is enjoying the summers. It is often said, ‘If you want to celebrate Christmas in summer, then go to Australia’. Well, this is because of the phenomenon that is explained above.

Therefore, the correct answer is B

Note:

> The tilt of the earth is also the reason why days are shorter during the winters and longer during the summers.> This difference is felt mildly at the equator and felt very drastically as we move towards higher latitudes.> At the poles this effect is so prominent that it remains daytime for half the year and nighttime for the next half of the year.

A season is a period of the year that is distinguished by special climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each has its own light, temperature, and weather patterns that repeat yearly.

In the Northern Hemisphere, winter generally begins on December 21 or 22. This is the winter solstice, the day of the year with the shortest period of daylight. Summer begins on June 20 or 21, the summer solstice, which has the most daylight of any day in the year. Spring and fall, or autumn, begin on equinoxes, days that have equal amounts of daylight and darkness. The vernal, or spring, equinox falls on March 20 or 21, and the autumnal equinox is on September 22 or 23.

The seasons in the Northern Hemisphere are the opposite of those in the Southern Hemisphere. This means that in Argentina and Australia, winter begins in June. The winter solstice in the Southern Hemisphere is June 20 or 21, while the summer solstice, the longest day of the year, is December 21 or 22.

Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. Earth’s axis is an invisible line that runs through its center, from pole to pole. Earth rotates around its axis.

In June, when the Northern Hemisphere is tilted toward the sun, the sun’s rays hit it for a greater part of the day than in winter. This means it gets more hours of daylight. In December, when the Northern Hemisphere is tilted away from the sun, with fewer hours of daylight.

Seasons have an enormous influence on vegetation and plant growth. Winter typically has cold weather, little daylight, and limited plant growth. In spring, plants sprout, tree leaves unfurl, and flowers blossom. Summer is the warmest time of the year and has the most daylight, so plants grow quickly. In autumn, temperatures drop, and many trees lose their leaves.

The four-season year is typical only in the mid-latitudes. The mid-latitudes are places that are neither near the poles nor near the Equator. The farther north you go, the bigger the differences in the seasons. Helsinki, Finland, sees 18.5 hours of daylight in the middle of June. In mid-December, however, it is light for less than 6 hours. Athens, Greece, in southern Europe, has a smaller variation. It has 14.5 hours of daylight in June and 9.5 hours in December.

Places near the Equator experience little seasonal variation. They have about the same amount of daylight and darkness throughout the year. These places remain warm year-round. Near the Equator, regions typically have alternating rainy and dry seasons.

Polar regions experience seasonal variation, although they are generally colder than other places on Earth. Near the poles, the amount of daylight changes dramatically between summer and winter. In Barrow, Alaska, the northernmost city in the U.S., it stays light all day long between mid-May and early August. The city is in total darkness between mid-November and January.
