What are the strengths and weaknesses of continental drift theory?

Answer 1

Strengths are the fact that the continents all fit like a puzzle. Also, there are many evidences that support the theory.

One, coal deposits (usually found in tropical climates) were found in the North Pole. Alfred Wegener concluded that NP could have been located near the equator when it was part of Pangaea.

Two, fossils of the same species were found in South America and South Africa. These organisms could not have travelled over the vast seas of present day. The only way to explain it was that these two pieces of land were connected.

Three, there were signs of glaciation at South America and Africa and the patterns of the striae left behind are similar in both continents, leading Alfred to believe they were connected.

Weakness was that people could not explain the forces or mechanism that caused these continents to move such great distances, until the 1960s, when plate tectonics was introduced.

I can't find/think of any more weaknesses but I hope this has helped brother. Peace.

Answer 2

Continental drift is the movement of the earth's continents across the ocean's bed relative to one another. There is no disadvantage as such of this theory however it has certain weaknesses. One of the weakness is that people could not explain the forces that caused these continents to move such great distances.

Answer 3

Because it cannot actually be proved, you only have a bit of evidence that hints towards it.
