A glacier is a large, slow-moving mass of ice typically found far away from the Earth's equator. However, scientists have found many rocks in Africa with scratches made by glaciers. What conclusion can be drawn from this evidence?
The presence of rocks in Africa with scratches made by glaciers suggests that glaciers were present in Africa at some point in the past. This conclusion indicates that the climate in Africa was colder than it is today, allowing for the existence of glaciers.
