Where do scientists begin the story of Earths history?One place to start is by looking at the age of the materials that make up the Earth itself.

It fails to qualify as a science because it lacks empirical support, supplies no tentative hypotheses, and resolves to describe natural history in terms of scientifically untestable supernatural causes.Cliffs, road cuts, and non-vegetated landscapes allow us glimpses into geology which is often hidden from view.Cliffs and road cuts are "side views" or "geologic cross-sections" of the topography which show the relative positions of various rock layers and structures at a given spot.Just as Sherlock Holmes used his power of observation to decipher the clues to a suspect's past actions, we will let the blemishes and behaviors of the rocks tell us their past story. ) Remember that relative dating involves determining "which came first" rather than "exactly when did this happen." The first step to untangling the geologic history of an area is often to figure out what happened first, second and third, etc.without knowing the absolute ages at which the rocks themselves formed.
