The passing of a year can bring a marked change in the weather and the surrounding environment. The four seasons — winter, spring, summer, autumn — can vary significantly in characteristics, and can prompt changes in the world around them. Let's take an overview of these four separate periods.
The annual cycle
Attributes of the seasons may vary by location, but there are still broad definitions that cross most of the boundaries.In the spring, seeds take root and vegetation begins to grow. The weather is warmer, and often wetter. Animals wake or return from warmer climates, often with newborns. Melting snow from the previous season, along with increased rainfall, can cause flooding along waterways, according to the Federal Emergency Management Agency (FEMA).
n the summer, temperatures may increase to their hottest of the year. If they spike too high, heat waves or droughts may cause trouble for people, animals, and plants. For example, in the summer of 2003, the high temperatures claimed more than 30,000 lives, according to Encyclopedia Britannica. Rainfall may increase in some areas, as well. Others may receive less water, and forest fires may become more frequent.
In the autumn, or fall, temperatures cool again. Plants may begin to grow dormant. Animals might prepare themselves for the upcoming cold weather, storing food or traveling to warmer regions. Various cultures have celebrated bountiful harvests with annual festivals. Thanksgiving is a good example. "Thanksgiving in the United States is a historical commemoration but it has a spiritual dimension strongly associated with homecoming and giving praise for what has been bestowed upon us," Cristina De Rossi, an anthropologist at Barnet and Southgate College in London, told Live Science.
Winter often brings a chill. Some areas may experience snow or ice, while others see only cold rain. Animals find ways to warm themselves, and may have changed their appearance to adapt. "In a similar way to the Autumnal theme, Winter festivals celebrate the return of the light during a time of deepest physical darkness," said De Rossi. The Indian festival of Diwali, for example, which takes place between October and November, celebrates the triumph of righteousness, and of light over darkness.
Respuesta:The four seasons of the year are: spring, summer, fall and winter. Each season lasts 3 months, with summer being the warmest season, winter the coldest, and spring and fall in between.
Spring begins around March 21 in the Northern Hemisphere and September 21 in the Southern Hemisphere. At this time of year, the flowers start to come out and the leaves grow on the trees. During this season the young of many animals are born.
Summer is the hottest season, the days are longer because the Sun provides direct light to the Earth. It begins around June 21 in the Northern Hemisphere and December 21 in the Southern Hemisphere. Corn crops are often harvested in late summer.
Autumn is the season of the year when the temperature drops, the leaves of the trees lose their green color and begin to fall. This season begins around September 21 in the Northern Hemisphere and March 21 in the Southern Hemisphere. Some birds migrate to warmer climates.
Winter begins around December 21 in the Northern Hemisphere and June 21 in the Southern Hemisphere. It is a season where it is colder, even snow falls in some regions. The days are shorter as the Sun provides indirect light to the Earth. The cold affects the behavior of animals, some animals like bears hibernate in the winter.
