This book describes how cities in the ancient world became buried under layers of earth and the elements that helped them get buried. Elements such as winds, water, earthquakes, tsunamis, volcano eruptions, the sun Ultra Violet rays, and the misdeeds of Man that participated in their burial. With the passage of time those cities were forgotten and disappeared from view. Later on, archaeologists, through research or by chance, dig them up and try to restore as much as possible what was left of those cities to find out how people lived in the past and what caused the destruction and disappearance of their cities.
