- 1. The average rapidity of the rain drop is only 8-10 km/h.
- 2. The water falls to the earth in low rapidity because rain drops have special shape that increase atmosphere friction’s effect and help rain falls to earth in lower rapidity.
- 3. The minimum height of the rain cloud is 1.200 m.
- 4. The effect of a drop of rain that falls from that height (1.200 m) is equal to a kg thing that falls from 15 cm height.
- 5. The rain cloud also can be found in 10.000 m height.
- 6. In 1 second, around 16 tons water evaporates from earth.
- 7. This quantity (16 tons) is equal to the quantity of the water that falls to earth in 1 second. In a year, it is assumed that this quantity is getting to 505*1012 tons. Water keeps turning within its balanced cycle based on its “dosage.”
- 8. The granules of rain drop change its shape hundreds times per second.
- 9. If the granule of the rainfall is frozen, it will form a piece of beautiful crystal, different from common water that is frozen in freezer.
- 10. After the rainfall, ground, coarse grasses, and weeds will expel special characteristics aroma. This aromatic smell called “Petrichor.”
- 11. Rain has hypnotizing ability that can hypnotize the human to resonate the past memories. And without be able to get the scientific evidences, the scientists only can conclude this; “Within the rain, exist songs that can only be heard by them who are yearning.” And at this rate, the scientists believe that ordinarily human get inspiration.
