Sunrise and sunset - a truly magnificent picture. In all its beauty, it unfolds in the open space - outside the city, in the field, and especially at sea. That part of the horizon where the sun rises and sets, is painted in crimson colors, as if an invisible artist touches the firmament with a magic brush.
How does the sun rise?
Early in the morning, the horizon in the east begins to slowly blush - it is morning dawn. The night gives way to day, gradually brightens, and the dawn increasingly floods the lower edge of the sky with fiery light.
Then, due to the part of the horizon where the sun rises, the upper edge of its disk slowly appears. Rising, it increases in size until it completely appears before the awakened earth in its royal radiance. At that moment, one gets the impression that it, like a huge ball of fire, hovers above its surface. But this does not last long. The sun, moving from left to right, begins to rise above the horizon. Its color changes from red to orange, and then to yellow. The dimensions of the star are decreasing, having reached the highest point above the horizon, it looks like a small light yellow ball.
How does the sun go down?
Having reached the highest point of its location, the sun begins to go down without changing the direction of movement. The lower it falls, the closer towards evening the picture of his morning ascent is more distinctly repeated in the sky. The part of the horizon where the sun sets is painted in red-fiery colors, and the disk itself is becoming larger. And now the evening dawn is burning violently at the edge of the sky, illuminating it, until the luminary hides beyond the horizon. This spectacle is bewitching and very beautiful. It inspires artists to paint paintings and romantics to seek adventure.
If you ask where the sun sets, everyone will answer - in the west, because, having risen in the east, it circles in the sky, sets again and continues to move on the other side of the earth. In fact, it is motionless, and this is our Earth revolving around it in orbit.
Why does the sky tint at sunrise and sunset?
As you know, the Earth is surrounded by an air shell - an atmosphere that extends upwards by about 1000 km. In the lower layers, it has a high density. The higher the surface of the Earth, the lower this indicator, and the atmosphere more rarefied.
Scientists have determined: the thicker the layer of the air shell, the fewer rays it passes through itself, and this applies mainly to blue and green radiation, which can not be said about red, orange and yellow rays.
Since the place where the sun sets and rises is in the lower layers of the atmosphere, its disk looks red-crimson during this period. Rising then into more rarefied layers, the Sun changes color, becoming lighter and more yellow.
What happens at the poles?
The North and South poles are considered unique places of our Earth. The daily coverage here is divided into a polar day (178 days) and a polar night (187 days). Regarding the poles, it is more appropriate to ask not "where does the sun go down", but "how does this phenomenon occur."
It turns out that only once a year there is sunrise and sunset. At the South Pole, the sun rises in September on the day of the autumnal equinox, and sets in March on the day of the spring equinox. At the North Pole, all of these phenomena are reversed. This is the part of the world where the sun rises and sets in March and September.
How is the sun arranged?
Our planet Earth is insignificant in size in relation to the Sun. Every day we bask in its rays and watch the sunrises and sunsets, but what do we know about this magnificent star?
Having figured out how the sun rises and where the sun sets, let's look at what it consists of.
This is a bunch of hot gas in the form of a huge ball, inside which a plasma consisting of various gases is constantly moving. Mostly it is hydrogen and helium.
Scientists divide the structure of the Sun into 4 parts:
- the core (central part) where the nuclear reaction occurs, namely: hydrogen, burning, turns into helium;
- a radiant zone in which gases move moderately, transferring energy from layer to layer outward;
- convection zone, consisting of rapidly moving gases;
- a region of the atmosphere that extends far beyond the visible part of the star, and during a solar eclipse is visible as a pearl halo - the crown.
Everything in our life is passing away, but the everyday sunrise remains unchanged, moving on its heavenly route for many billions of years.
In this article, we have uncovered many facts about where the sun rises and sets. We hope this information was useful and interesting to you.
