which of the following was evidence cited by alfred wegener that the continents were once one large land mass he called pangaea?
question 2 options:
similar fossils were found around the world
the ages, layers, and types of rocks on mountains in separated continents were the same
the shapes of the continents looked like they could fit together
all of the above

Option (4)

Explanation:

Some of the evidences put forwarded by Alfred Wegener supporting the continental drift theory are as follows-

(a) the coastlines of most of the continents were perfectly matched with one another, suggesting that the continents were earlier once all together.

(b) Similar fossils such as plant fossils glossopteris, gangamopteris and animal fossils marsupials were found in different continents which were separated in the geological history.

(c) Similar rock types were also found along the boundaries of the plates, whose ages are almost the same and are calculated by the use of co-relation method.

Thus, these evidences were helpful later in understanding the universally accepted plate tectonic movement that explains the mechanism behind the drifting of the continents. It was due to the convection current that generates in the mantle, is responsible for the motion of these plates.

Hence, the correct answer is option (4).
