About Rain

As we know, Indonesia is a tropical country, the general characteristics of the so called tropical, is having a lot of rainfall. In this thread we will discuss about the unique phenomenon of rain and the fact that may be overlooked by us.

1. Average rain fall velocity was 80-10 km / hr.
2. Water falls to earth with a low speed, because raindrops have a special form which enhance the effects of atmospheric friction, and help the rain come down to earth with the velocity is lower. Suppose a different form of raindrops, or suppose that the atmosphere does not have friction properties (imagine if rain occurs, such as large water bubbles that descend from the sky), the Earth would face destruction, each drop of rain.


3. The minimum altitude of rain clouds is 1,200 meters.
4. Effects caused by a drop of rain falling from a height, the same as the object weighing 1 kg falling from a height of 15 cm.
5. Rain clouds can be found at an altitude of 10 000 meters.
6. In one second, approximately 16 million tons of water evaporates from the earth.


7. This amount is equal to the amount of water that came down to earth in one second. Within one year, is expected this number will reach 505x1012 tons. Water continues to turn in a balanced cycle according to "measure".
8. Rain droplets change shape hundreds of times each second.


9. If rain water were frozen, will form a beautiful piece of crystal, not like ordinary water in the freeze in freezer / refrigerator.
10. After rain, soil, weeds, grass fragrance will issue an ax, this compound is called 'petrichor'.
11. And the last fact that most mysterious and surprising scientists......

Rain has the ability to hypnotize humans, to the resonance of past memories. And without being able to get the scientific evidence, scientists can only conclude that "In the rain, there was a song that could only be heard by those who miss".And at this point, scientists believed that humans usually get inspiration ..
