What evidence did glaciers leave in the bedrock in equatorial latitudes?

In equatorial latitudes, glaciers have left distinct marks on the bedrock known as scars and striations. These are physical features resulting from the movement of glaciers over the terrain. As glaciers advance and retreat, they can scrape and scratch the underlying rock, effectively carving out grooves known as striations. These linear marks provide valuable evidence of the direction of glacier movement, showcasing the immense forces exerted by the ice over geological time.

The presence of scars, which can appear as polished and smoothed areas, further indicates the abrasive action of moving glaciers. Glacial erosion is a transformative process, reshaping landscapes in various latitudes, including those that are currently tropical or equatorial. This evidence contributes to our understanding of past climatic conditions and glacial activity, even in regions where glaciers are not present today.

Other options, while relevant to geological formations, do not specifically pertain to the direct impact of glaciers on the bedrock in these latitudes. Fossils and remains, for example, relate more to biological activity and not to glacial processes. Mineral deposits could result from a variety of geological processes unrelated to glaciers. Soil layers represent more stable, long-term geological conditions rather than the immediate effects of glacial movement. Thus, only
