At What Altitude Do Clouds Stop Forming?

At What Altitude Do Clouds Stop Forming?

Clouds are formed when air contains as much water vapor it can hold, reaching what is called the saturation point. There are three classifications for clouds: Low are 50 feet to 6,500 feet; middle are 6,500 feet to 20,000 feet; and high are 20,000 feet and above. Hurricanes arise from cumulonimbus clouds which can grow to heights of 65,000 feet. Beyond this height, the atmosphere does not hold water and clouds do not form.

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1910, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
