how were the continents formed
Wegener couldn't explain how or why continents moved.

Wegener's theory of continental drift proved the theory of Pangea (all continents as one land mass).
Wegner hypothesised that the continents 'drifted' into their current positions over time and originally formed one supercontinent.
Wegener believed all continents had once been joined because of the similar shapes of coastlines, matching geological formations across continents, and evidence of past glaciation extending from multiple continents, suggesting they were once connected.
Wegener proposed the theory of continental drift because he noticed how coastlines of continents seemed to fit together like pieces of a puzzle. He also observed similarities in rock formations, fossils, and climate across continents that suggested they were once connected. These observations led him to suggest that the continents had moved over time.
