According to Wegener's theory of continental drift, what happened to the continents?

• The continents were once joined together in a single landmass and have slowly moved.

• The continents have always been in their current positions.

• The continents were formed by volcanic activity.

• The continents are constantly expanding due to tectonic activity.
