Earth's surface area is about 510,000,000 km2 or 510,000,000,000,000 m2.
1 mm = 0,001 meter, so the volume is 510,000,000,000,000 m2 * 0,001 m = 510,000,000,000 m3.
1 m3 = 1000 liter so 510,000,000,000 m3 = 510,000,000,000,000 liters or 510 trillion liters (or teralitres).
Another way to put it is that 1 mm per m2 is 1 liter per m2 and you have the area above.
510 teralitres is 510 km3 and that is a little bit more than Lake Erie (480 km3).
1 litre will be collected per square meter of surface area from one millimeter of rain
Absolutely.
There are 19 liters of water in 19 liters.
they get water when it rains
mm is a measurement of length - millimeters - while liter is a measure of volume. However, the conversion for water is that one cubic millimeter equals one milliliter. Therefore, for pure water, there are 1000 cubic millimeters in one liter.
is the amount of water on earth added to every time it rains
Something like 326,000,000,000,000,000,000 gallons (326 million trillion gallons) of water (roughly 1,260,000,000,000,000,000,000 liters) can be found on our planet. This water is in a constant cycle -- it evaporates from the ocean, travels through the air, rains down on the land and then flows back to the ocean.
it rains
No
it rains
the liters of water in a bag of potato chip is 2 liters
The precipitation is much higher in that climate. So, when all the water evaporates, it goes up into the clouds. When the clouds are full of water, they release the water so it rains. And since there's a large amount of water, it rains much more frequently
