Final answer:

Glaciers leave scratches on rocks known as glacial erratics, indicating past locations of glaciers different from their current positions.


Explanation:

Glaciers leave scratches on rocks as they move over the land, carrying rocks of various sizes for many miles. These rocks, known as glacial erratics, are left behind when the glacier melts, often far from their origin. The presence of rocks in Africa with scratches made by glaciers suggests that at some point, parts of Africa were once located farther away from the equator where glaciers existed.
