Question

Alfred wegener suggested that earths continents are moving. Which evidence support this theory

Answer 1

As explained below

Step-by-step explanation:

• Alfred Wegener was the first to give the continental plate theory in 1912 and IT gained popularity in 1950 onwards when the publication came from the geologist and other scientists that proved that continent are spreading and as seafloor is itself moving and the evidence that he gave doe the theory are given as below.

1. Drifting away from the continents due to the pole wandering forces.

2. Jigsaw ft puzzle that coasts of South America and those of Africa have the same geologic and tectonic origin.

3. Presence of large and long mountain chains of mountains and ranges present in all the contents that form a chain.

4. Floral and Faunal evidence found in the lands of South America and Africa and the opening of the s-shaped Atlantic ocean that separated them apart.

5. Presence of similar climatic zones over the continents of the Gondwanaland and the northern Laurentia continent.

• The seafloor spreading supports the evidence by the study of paleomagnetism and the age of rocks.

Answer 2

Close geometric correspondence of continental coastlines.

Step-by-step explanation:

• The main supporting clues that Wegener used were the geomorphological shape of the opposing continents across the Atlantic. Further evidence derived from the study of the continental shelf below the sea; the matching geometry is even better than the one of the emerged shoreline.
• Another strong supporting evidence is the presence of rocks of identical geological origin on different continents. It is actually possible to follow the strata limits on landmasses that now are separated by oceans. It is a strong clue that once these masses belonged to the same continent.
