Characteristics of the Four Seasons
Seasonal change is caused by the axial tilt of the Earth, which creates climatic differences due to greater or lesser exposure to solar radiations. The characteristics of these seasons are briefly examined below.
In the Northern Hemisphere, spring lasts from almost March 20 to effectually June 20. The commencement day of spring is known as the vernal equinox where the hours of day and night are equal. As the flavor progresses, the days abound longer and the air warmer. Plants move out of their winter dormancy, begin to sprout and put along buds and fresh leaves. Animals also, mark the change. Birds brainstorm nesting and migratory species kickoff the trek from winter to summer territory. Hibernating creatures get out their dens and burrows. Humans also recognize leap, with celebrations of fertility and growth. More practically, gardens and fields are tilled and planted, gear up to grow and ripen in the warmth of summer.
The Northern Hemisphere summer begins with the solstice, occurring about June 21, the longest day of the year. The long hot days incite a period of growth and ripening. Plants put along fruit and seeds; young animals grow and learn. Herbivores accept advantage of the abundant food to store fat for the coming winter and carnivores prey upon the institute-eaters for the same purpose. Humans too, savour the flavor, with its greater access to fresh to the fresh fruits and vegetables establish at farmer’due south markets and roadside stands. It’s a time of plenty and preparation for the colder times alee.
The autumnal equinox marks the kickoff of fall in the Northern Hemisphere. Information technology’s the mirror of bound as warmth and affluence tail away to libation temperatures and dwindling resource. Days keep to grow shorter and plants fall into dormancy. Migratory animals begin the journey to winter quarters and hibernating species prepare for torpor. Creatures that don’t migrate may grow thicker coats of fur or down to hold off the looming winter arctic. For humans, information technology’s the season of harvest, frequently marked by feasts. Even with year-circular food available in the modern grocery shop, many people employ this time to store food for the winter by canning, drying or freezing and thus savour the memory of summer in the dark of winter.
Equally in summer, the advent of winter is marked past a solstice. Occurring around December 21, it has the shortest day and longest night of the yr. For much of nature, wintertime is a time of slowing down as temperatures grow colder. Most plants are quiescent and many animals slumber a great bargain or even hide. This conserves energy at a fourth dimension when at that place are fewer resources available. Despite being the showtime of the coldest season, the solstice marks the time when the days starting time to grow longer. Human cultures across the globe and throughout history marker this time with feasts and celebrations. These remind all that jump will come once more.
The dates above refer to the astronomical seasons, adamant by the Earth’s journey around the sun. Meteorological seasons are adamant past weather weather condition and follow a somewhat different schedule. Also, the Southern Hemisphere seasons are opposite those north of the equator.
