How did rain start?
Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air.
This vapour rises, cools, and changes into tiny water droplets, which form clouds.
When the water droplets get too large and heavy, they fall as rain..
Is it ever not raining in the world?
Yes. Thanks to the Earth’s water cycle, it is always raining in some part of the world every day. … This water cycle is constantly working in the Earth’s atmosphere, all over the world. So at any given point, it is raining somewhere on the Earth due to the water cycle.
What would happen if it never rained again?
Rivers would dry up, crops would fail and our green and pleasant land would start to look pretty desperate. In fact after just a year without rain, desert conditions would start to occur. Land could be irrigated, but that would mean tapping precious underground reserves.
Where does it rain the most?
1. Mawsynram, Meghalaya, India. The place that records the highest rainfall on the Earth is Maysynram, located in Meghalaya, India. Located only 15 kms from Cherrapunji, villagers in Mawsynram use grass to soundproof their huts from the deafening rain that pelts their homes during the rainy season.
Where is the driest place on Earth?
Atacama DesertThe Atacama Desert in Chile, known as the driest place on Earth, is awash with color after a year’s worth of extreme rainfall. In an average year, this desert is a very dry place.
What’s the rainiest state in America?
Hawaii overall is the rainiest state in the US, with a state-wide average of 63.7 inches (1618 millimetres) of rain a year.
Who discovered how clouds are formed?
– First physical theory (no water dissolution in air) by Deluc (1787), – First cloud classification by Lamarck (1802) and Howard (1803), – Water condenses only on particles by Aitken (1881), – Final evidence that clouds consist of droplets and not vesicles by Aßmann (1885).
What does 10mm of rain mean?
10 mm rainfall means that if rainfall fell on a flat land surface , with no slope ,no evaporation, and no percolation of water I.e. water does not go underground, then the amount of rainfall would be 10 mm measured from the ground.
What is the longest it has ever rained?
In the Lower 48, the longest stretch any location has seen measurable precipitation (rain/snow) is 79 days near Otis, Oregon, in the winter of 1997-98. Alaska’s record of 88 consecutive days with measurable precipitation was set in Ketchikan in 1920.
What would happen if it rained forever?
If we had continuous rain, we would initially have major problems with floods. But eventually things would settle down to a new equilibrium. Existing rivers will swell, and would not reduce back in size, as the rains do not stop. New rivers may form, as all the excess water seeks new channels to flow back to the sea.
Did it rain 2 million years?
Something strange happened in the Late Triassic — and not just in Somerset. About 232 million years ago, during a span known as the Carnian age, it rained almost everywhere. After millions of years of dry climates, Earth entered a wet period lasting one million to two million years.
Is rain water clean?
Most rain is perfectly safe to drink and may be even cleaner than the public water supply. Rainwater is only as clean as its container. Only rain that has fallen directly from the sky should be collected for drinking. … Boiling and filtering rainwater will make it even safer to drink.
When was the first rain on Earth?
3.8 billion years agoAt this time, about 3.8 billion years ago, the water condensed into rain which filled the basins that are now our oceans. Most scientists agree that the atmosphere and the oceans accumulated gradually over millions and millions of years with the continual ‘degassing’ of the Earth’s interior.
What country has no rain?
Chile’sBut the driest non-polar spot on Earth is even more remarkable. There are places in Chile’s Atacama Desert where rain has never been recorded—and yet, there are hundreds of species of vascular plants growing there.
Does rain clean the air?
As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, and organic particles.
