Which coal field location is related to coal fields in the eastern united states and supports the theory of continental drift? eastern india southern africa western australia northern south america

The correct answer is Southern Africa.  

The coal fields witnessed in the Southern part of Africa and the eastern part of the United States are a direct proof, which supports the continental drift theory. The reason is that the coal fields found in both the locations are formed of a similar kind of trees, and are produced in the same period.  

This suggests that the continents were once combined together. The kind of tree, which provided the basic substance for the coal is similar, and the trees, which are entirely similar is almost impossible to be found in separated continents, as they will exhibit certain kind of changes, which will distinguish them. The period and the climate during which the formation of coal took place is also exactly similar, this also leads to the supposition that there was once a huge associated mass of land.  

satellites are frequently used to make observations of the orbit on earth

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
