The continental drift theory put forward by the Alfred Wegner stare that the continental land got separate by the drifting of the plates that the oceans mas as they were close together in the form of a supercontinent, and are now separated by the large ocean bodies like that of the Jigsaw fit.
The tropical species that were found in the equatorial belt s are now found in the island that is near to the place the dominance of the movement of the tectonic forces and the flight to poles explained in his theory.
<u>The coalfields that found in North America are similar to that of the European landmass that got separated and drifts away. Thus the S shape of the atlantic oceans is characteristic of this.</u>
Potassium argon dating is a method used in determining the origin of a rock. I is done by comparing the ratio of radioactive argon to radioactive potassium in the rock. This method is used to date rocks that are thousands of million years old.
the assumptions made when using the Potassium argon dating include :
no argon was left after formation of the rock
no argon has either entered or escaped the sample since it was formed.
