Will award brainliest wegener observed evidence of the similarity between the type and age of rocks at the edges of continents. which of the following best describes the reason for continents to have the same types and ages of rocks on their edges? 1)glaciers created the edges of the continents as they moved rocks from one continent to another. 2)ocean waves weathered the edges of the continents so they appeared to look like giant puzzle pieces. 3)wind erosion carries pieces of rock away from the continents exposing similar rock types. 4)the continents were part of an ancient, single landmass called pangea that moved apart over millions of years.

Glaciers created the edges of the continents as they moved rocks from one continent to another.

Ocean waves weathered the edges of the continents so they appeared to look like giant puzzle pieces.

Wind erosion carries pieces of rock away from the continents exposing similar rock types.

The continents were part of an ancient, single landmass called Pangea that moved apart over millions of years.

THE FIRST ONE IS CORRECT I THINK. CAN I HAVE BRAINIEST?

Option (4)

Explanation:

The continental drift theory refers to the large scale motion of the continents over the vast ocean body and it was initially discovered by Mr. Alfred Wegener.

He contributed many evidences in support of this theory and determined that the age of the rocks and the types of rock that are found in the continental edges are the same.

It was possible for him to conclude this because he was sure that the present continents were all a part of the ancient large super-continent named Pangaea, which was broken down into Laurasia and Gondwanland and further broken down into different smaller plates over millions of years, due to the mechanism of convection current which was later modified by the theory of plate tectonics.

Thus, the correct answer is option (4).
