How much water falls back as rain during the water cycle?
During the water cycle, approximately 78 of the water that evaporates falls back as rain.
What is the average miles per hour that a rain drop falls?
The average speed at which a raindrop falls is around 7 to 18 miles per hour. However, this speed can vary depending on the size of the raindrop and the air resistance it encounters.
How can one determine the intensity of rainfall?
The intensity of rainfall can be determined by measuring the amount of rain that falls in a specific area over a certain period of time. This is typically done using a rain gauge, which collects and measures the volume of rainwater. The intensity of rainfall is often expressed in millimeters per hour or inches per hour, indicating how much rain is falling in a given time frame.
What happens if too much rain or snow falls at once?
If too much rain or snow falls at once, it can lead to flooding, landslides, or avalanches. Excessive rainfall can overwhelm drainage systems, causing water to accumulate and flood low-lying areas. Heavy snowfall can increase the risk of avalanches in mountainous regions and cause roofs to collapse under the weight.
How much rain is considered a lot in an hour?
In general, rainfall of more than 0.3 inches in an hour is considered a lot.
