However, relative methods are , which is that if there are layers of deposits, those laid down first will be on the bottom and those laid down last will be on the top. However, geological strata are not always found to be in a neat chronological order.Wind and water erode strata and some areas are uplifted or even tilted.
Geologists have used this method to date rocks as much as 4 billion years old.based on the fact that amino acids progressively change to mirror image forms following the death of an organism--i.e., from L-amino acid to D-amino acid forms.Aspartic acid in organic samples is commonly used for this dating technique.things that are intentionally made according to a cultural pattern or inadvertently modified as a result of culturally patterned behavior.Archaeology has undoubtedly enriched mankind’s history like no other science.There is a greater part of man’s unwritten past that archaeology has managed to unravel.Potassium (K) is one of the most abundant elements in the Earth's crust (2.4% by mass).
