It took more than two years for the scientists to observe how bacteria "eat" stones.
Time of Update: 2020-07-27
rocks form soil through weathering reactions, but this process is difficult to observe for humans.
and organisms that use stone as an electronic source are called chemoautotrophs, which can eat rocks for a living.
therefore, bacteria can indeed initiate and accelerate the process of rock weathering into soil.
