HELP PLEASE!! Wegner was not the first scientist to present the idea of continental drift. What did Wegner add to his theory to convince scientists that continents were once connected together?

Explanation:

Wegener found that large-scale geological features on separated continents often matched very closely when the continents were brought together. ... Wegener was not the first to suggest that the continents had once been connected, but he was the first to present extensive evidence from several fields.

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )
