Spring 2021 Google Doodle : Spring is one of the four seasons where the days get longer and the weather gets warmer, especially in the temperate zone. This is due to the fact that the earth tilts relative to its orbital plane around the sun.
It is also the season where animals breed and flowers bloom. Spring is also the period where many educational institutions and universities have a vacation around the world.
Google Celebrates the beginning od Spring 2021 with a Doodle.
In 2021, the spring equinox occurs on Saturday, March 20. This event marks the astronomical first day of spring in the Northern Hemisphere. What does equinox mean? What happens on the equinox? What determines the first day of spring
In the Northern Hemisphere, the March equinox (aka spring equinox or vernal equinox) occurs when the Sun crosses the equator line, heading north. This event marks the start of spring in the northern half of the globe. After this date, the Northern Hemisphere begins to be tilted more toward the Sun, resulting in increasing daylight hours and warming temperatures. (In the Southern Hemisphere, it’s the opposite: the March equinox marks the start of autumn, as the Southern Hemisphere begins to be tilted away from the Sun.)
In 2021, the March equinox happens on Saturday, March 20, at 5:37 A.M. EDT. In the Northern Hemisphere, this date marks the start of the spring season.
In the Southern Hemisphere, the March equinox marks the start of autumn, while the September equinox marks the start of spring.
From an ecological perspective, the spring season is not always determined by prefixed calendar dates. Instead, spring is marked by various biological indicators such as blooming flowers and breeding activities of animals. Even the soil has a characteristic smell, and it becomes warm enough for microorganisms in the soil to flourish. Ecologists have even divided the year into six seasons, with spring season being classified into “prevernal spring” (early spring) and “vernal spring”.
To sum up, the spring season is the season where flowers bloom and animals breed, it is also the season where days get longer and the weather gets warmer compared to other seasons.
On the March equinox, the Sun crosses the celestial equator going south to north. It’s called the “celestial equator” because it’s an imaginary line in the sky above the Earth’s equator.
If you were standing on the equator, the Sun would pass directly overhead on its way north.
