Some meteorites, such as Stannern, have tiny bumpy lines—called flow lines—running down their sides, like wax drippings on a candle. Flow lines form on meteorites that hold a fairly stable orientation as they pass through the atmosphere. Air pressure melts the surface and pushes the droplets backward. As the rock cools, the last flowing drips freeze into flow lines.
