The correct conclusion that can be drawn from the evidence of rocks in Africa with scratches made by glaciers is:
B. Parts of Africa were once located farther away from the equator.
Explanation:
1. Glaciers are large, slow-moving masses of ice typically found far away from the Earth's equator.
2. The presence of rocks in Africa with scratches made by glaciers suggests that these rocks were transported and scratched by glaciers.
3. Since glaciers are typically not found near the equator, the rocks with glacial scratches indicate that these parts of Africa were once located in regions where glaciers existed.
4. Therefore, the most reasonable conclusion is that parts of Africa were once situated farther away from the equator where glaciers were present, allowing them to scratch the rocks.
