millions of years ago ( i dont know the axact date) there was a supervolcano in africa, a believe. this eruption sent tonnes of ash into the upper atmosphere. this ash gradually settled out and fell to earth. the ash is obviously thickest nearer the volcano and then gets gradually thinner. in the round earth model, the thinnest layer of ash is on the opposite side of the earth, but in the FE model, it just gets thinner and thinner until it reaches the edge of the earth. if we were to look at the FE with this data on it , the we would see that the ash gets thinner but then as it gets close to the edge of the map, it starts to get thicker again.
can you explain this
