Here are facts about the rain based on analysis of competent experts.

• The average speed of rain water fall is just 80-10 km/hour.  
• Water falls to earth with a low speed because raindrops have a special shape that increases the effects of atmospheric friction and help the rain come down to earth with a lower speed. Suppose a different form of raindrops, or assume the atmosphere does not have friction properties (imagine if rain occurs as a large bubble of water that fell from the sky), the earth will face the destruction of every drop of rain.
• Minimum altitude of rain clouds is 1,200 meters.
• Effect is caused by a drop of rain falling from a height is equal to 1 kg object falling from a height of 15 cm.
• Rain clouds can be found at an altitude of 10,000 meters.
• Within one second, approximately 16 million tons of water evaporates from the earth.
• This amount is equal to the amount of water that fell to earth in one second. Within one year, is expected this number will reach 505 × 1012 tons. Water continues to spin in a balanced cycle based on the "dose".
• Pellets of rain change shape hundreds of times per second.
• If it was frozen water droplets rain will form a beautiful crystal pieces, unlike ordinary water is frozen in the freezer/refrigerator.
• After rain, soil, weeds, grasses will issue a distinctive fragrance, these compounds are called 'petrichor'.
