How much rain falls per year?

The amount of rainfall varies significantly across the world, with some areas receiving very little rain and others receiving several meters per year. On average, the Earth receives about 1,000 millimeters (39 inches) of rain per year. However, this amount varies greatly from region to region, with some places receiving less than 25 millimeters (1 inch) per year and others receiving more than 10,000 millimeters (393 inches) per year.

The wettest places on Earth are typically located near the equator, where warm, moist air rises and condenses to form clouds and rain. The wettest place on Earth is the town of Mawsynram in India, which receives an average of 11,872 millimeters (467 inches) of rain per year.

The driest places on Earth are typically located in the desert regions of the world, where the air is very dry and there is very little rainfall. The driest place on Earth is the Atacama Desert in Chile, which receives an average of less than 1 millimeter (0.04 inches) of rain per year.
