Final answer:
The query involves analyzing topographic maps to determine glacier flow direction and understanding the impacts of glacier and iceberg melting on water levels. It incorporates topics like drumlins, the Little Ice Age, and the principles governing the displacement of water.
Step-by-step explanation:
The question posed appears to be related to geography, more specifically, it is about the study of glaciers, their movement, and the influence they have on landscapes. Students are being asked to determine the direction a glacier was traveling based on a topographic map and the landmarks left by such a glacier, like drumlins. Furthermore, the question explores the impact of glaciers melting and how this affects water levels in a lake nearby. Geographical tools used include topographical maps, scale understanding, and landscape interpretation.
For example, drumlins are oval-shaped mounds that are formed under glacial ice sheets due to glaciation. They can tell us the direction of glacier movement, as glaciers move towards the shallower side of these mounds. When considering the melting ice, typically the glacier on land would contribute more to the lake's water level, given that the iceberg floating in the water has already displaced its own volume, according to Archimedes' principle.
Regarding the historical aspect:
The Little Ice Age and its impact on glacier formation and moraine creation in places like Glacier National Park are also mentioned. This historical context is essential to understanding current glacier sizes and conditions.
