Answer 2

Answer:

Explanation:

Wegener contributed 4 tests to formulate his theory of continental drift:

* Geographical: Wegener suspected that the continents  in the past they could have been united by observing  a great coincidence in the form of the coasts of  all of them, especially between South America and Africa.

Which means that if in the past these  continents would have been united forming one  alone (Pangea) it is logical that the fragments fit.

* Paleontological: these are among the most evidence  important to demonstrate the above, that is,  in the past the continents of Africa and South America  they were united; or what is the same, fossils  coincided on both sides of the Atlantic.

This test shows that the continents  were gathered at some past time.

* Geological and tectonic: if the continents join in  one can only observe that the types of rocks, their  chronology and mountain ranges would have  physical continuity, that is to say they would form a belt almost  continuous.

* Paleoclimatic: according to Wegener these were the  most important tests for him.  The scientist discovered that there were areas on Earth  whose current climates did not match those they had  in the past.
