Very tall mountains
For years geologists have wondered exactly why the Himalayan Mountains are so impressively tall. Recently they have discovered the reason. It is because of a massive plate that slid off of them so that they would rebound dramatically. OK, so maybe it is more complicated than that, with some controversy sprinkled in. The point is, geologists are still making discoveries about things as seemingly simple as why the biggest mountains in the world are big.
