As we know, Indonesia is a tropical country, the general characteristics of the so-called tropical region is to have a lot of rainfall. In this article we will discuss about the unique phenomenon of rain and the fact that we might have missed from.
1. The average rain fall speed is 8-10 km / h.
2. Water falls to the earth with a low speed because of rain has a special form that enhances the effects of atmospheric friction and helps it fall to earth with kecepat's lower. Suppose different forms of rain, or the atmosphere does not have the properties of friction (imagine if rain occurs as a large bubble of water that fell from the sky), the earth will face the destruction of any rain.
3. Minimum altitude of rain clouds is 1,200 meters.
4. Effect caused by a drop of rain falling from a height is equal to 1 kg object falling from a height of 15 cm.
5. Rain clouds can be found at an altitude of 10,000 feet.
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 fell to earth in one second. In one year, this number is expected to reach 505 × 1012 tons. Water continuously circulates in a balanced cycle according to "measure".
8. Rain droplets change shape hundreds of times each second.
9. If it rains the water droplets frozen crystals will form beautiful pieces, unlike in ordinary water freeze in freezer / refrigerator.
10. After it rains, soil, weeds, grasses will issue a fragrant smell that distinctive, this compound is called 'Petrichor'.
11. And the last fact that most mysterious and surprising scientists. Rain has the ability to hypnotize people for me-resonance-kan memories of the past. And without access to scientific evidence, scientists can only conclude "In the rain, there is a song that can only be heard by those who missed".
And at this point, scientists believe that humans usually get inspired ..
