Relative dating biology anonymous dating questions
the word biology is composed of two Greek words "bioes" and "logoes".
bioes means "life" and "logoes" means "to discuss" hence biology is the branch of natural science in which we study about all aspects of modes of the life of living organism either present in this world.
Throughout the history of life, different organisms have appeared, flourished and become extinct.
Many of these organisms have left their remains as fossils in sedimentary rocks.
Correlation with them has helped geologists date many New Zealand rocks, including those containing dinosaurs.
The shales were deposited initially in a horizontal position, and then there is an earthquake, which made them all fold.
It sounds like common sense to define you and me, but the geologists have, the assumptions of rocks the principle of Original horizontality, the relative age of the sediment.
So, normally, we use relative Dating to come up with a ballpark and then use the numeric dating for special items such as fossils.
Relative Dating can't give us the actual age of a rock tell; it can only tell us whether a rock is older or younger than another.
The law of Superposition, if we Even assume that all the layers are originally horizontal, we can make a further assumption: that the oldest rock layers, which are furthest to the bottom and the youngest layers closest to the top.
