Answer:
Glaciers that once covered South Africa have melted and can no longer form.
Step-by-step explanation:
About 300 million years ago, Present day South Africa was lying very close to the south pole. The result was that the high lands were covered by a vast expanse of glacial sheets. Over millions of years, tectonic activities and movement gradually moved South Africa up northwards until the region came to be in its present warmer location. The movement into warmer latitudes caused the ice sheets to melt, causing the water stored as ice to move into the oceans around the coastline of South Africa.
