Let’s learn about rain

Precipitation might ruin your picnic, but life can’t go on without it

Rain, rain, go away. Many people aren’t very happy when a rainy day ruins their outdoor plans. Even worse, rain can fall in extreme amounts, especially during hurricanes and cyclones. Too much rain can result in floods that destroy homes and lives.  

Climate change has changed where rain falls, and how much. For instance, more water now gets dumped on cities during hurricanes. Climate change also moves where rain falls, so some areas that previously received plenty of rain have since been left high and dry.

But rainfall is also crucial to our life on Earth. It’s one part of the water cycle that allows life on land to exist. Farmers need rain for their crops. We also need rain to fill the reservoirs that provide drinking water.

Sometimes there’s too much rain. Sometimes there’s too little. Sometimes it’s just right. No matter what, we can’t live without it. So scientists spend a lot of time studying rain, where it falls and when. They’ve even found that rain might fall on other planets.
