Why do archeologists have to dig into the soil/sediment to find artifacts and archeological sites? Why are older things always deeper in the ground? Why would they not be found on the same level? Can dirt and debris pile up that bad?
In: Geology
Things lay on the ground or crumble. Over time they sink or are buried by the natural build up of sediment.
Think of something you own or have dropped, especially something metal, sturdy, and heavy. A few years later you find it half buried. Or maybe you find it with a metal detector and say “I was wondering what happened to this lock!” Or “I knew i left this shovel out”
