The evidence of climate change that supports the theory of continental drift is best indicated by glacial evidence found in South Africa.
This is because glacial deposits and striations found in currently warm regions, such as Africa, suggest that these areas were once located near the South Pole when the continents were arranged differently, supporting the notion that continents drifted over geological time. The presence of coal fields in several continents, while indicative of past climates, does not directly relate to continental drift in the same way as glacial evidence does.
