Explain the difference between radiometric and relative dating Webcamcook sex hot chat
we often make reference to fossils to explain the past of living beings. Fossils are remnants (complete or partial) of living beings that have lived in the past (thousands, millions of years) or traces of their activity that are preserved generally in sedimentary rocks.
Have you ever wondered how science knows the age of a fossil? If you think of a fossil, surely the first thing that comes to your mind is a dinosaur bone or a petrified shell that you found in the forest, but a fossil is much more.
The oldes tknown fossils are The magnetic north pole has changed throughout the history of Earth and its geographical coordinates are known in different geological eras.
Some minerals have magnetic properties and are directed towards the north magnetic pole when in aqueous suspension, for example clays.
Because this assignment is linked with your work in Assignment 3, you will have "If Scientists Think. Before scientists had modern technology to assist them in their research, they had to use their power of observation to infer the relative ages of the rocks they were studying.
The process of Relative Dating was established by Nicholaus Steno in the 1600's.
In addition to the "relative" uncertainty that the geological features of an area have retained their historical integrity, there is another problem associated with relative dating.But when laid on the ground, they are fixed to the position that the north magnetic pole was at the time.
