What are three pieces of evidence Alfred Wegener used to support the continental drift theory?

Coastline fits between different continents, similar rocks and fossils on different continents.

Three evidences used by Alfred Wegener to support the continental drift theory were: 1) the shapes of the continents, 2) the distribution of geological formations and 3) the movement of the continents.

Explanation:

Evidence 1:

The shapes of the continents on each side of the Atlantic Ocean seem to fit. It is very visible in the form of Africa and South America.

Evidence 2:

The distribution of some geological formations and the fossil record of the northern continents showing that they shared flora and fauna in past geological times.

Evidence 3: The movement of the continents inferring that they move over another denser layer of the Earth, which formed the ocean floor. This evidence has been debated and is currently considered only one hypothesis.

These data allowed Wegener to calculate that the current continents were united in a remote past of the Earth, forming a supercontinent called "Pangea".
