Eli5 How did ancient drawings in caves survive thousands of years without wearing away completely?
In: Earth Science
Think of writing something on paper. Inside your house that paper is going to be fine. It’ll sit on the table and just kinda be looked at. But bring it to the beach and leave it on the sand without touching it. It’ll get dirty buried in the sand by the wind, maybe even taken out to ocean if the tide comes in.
The difference is inside away from the elements that paper is protected, but outside many things can happen that would destroy it or cause you to lose it.
