Wegener observed that that coastlines of continents in the southern hemisphere had similar grooves. which of the following supports coastlines far away from one another having similar grooves? animal extinction glacial movement rock formation human interactionc

B, glacial movement.

Wegener observed similar grooves along the coastlines of continents in the Southern Hemisphere. These grooves were created by the movement of glaciers. Glaciers generally move in one direction. This movement creates large scratches in rock structures.
