Okay, you've got a cutaway hillside.  Is stuff at the bottom of pile older or newer than stuff at the top of the pile?

whpalmer4 · Answer

The stuff at the bottom of the pile must have evolved before the stuff piled on top of it, right? :-)

older stuff has to be at the bottom.  Look at the symbols along the bottom of the diagram, especially toward the left (which represents the interior of the hillside.
