REAL LIFE NEWS: RAINDROP HAZARD

by Hazed

This just in: raindrops can damage the Earth. No, not massive rainstorms or floods or deluges or water, but individual raindrops. We're all doomed!

Scientists have discovered that when a raindrop hits the ground, it results in a violent collision. It may happen on a microscopic scale, but the impact has the force of a hammer. The researchers from Arizona State University and Vanderbilt University conducted several experiments simulating raindrops hitting sand on flat surfaces and said their findings might have a big impact on research into soil erosion.

In arid and semi-arid regions where the hills don't have much vegetation, raindrops directly and dramatically affect soil as they hit. This new research will add to the knowledge engineers use to devise systems which prevent erosion of hills and mountains.
