Final answer:
To determine if you are in an area affected by glaciation from a castle window, look for an end moraine, drumlin, fjord, or glacial till, as each feature is indicative of past glacial activity.
Step-by-step explanation:
If you are being held captive in a castle and can view the landscape from a tower window, certain erosional features could indicate that you are in an area that was subjected to glaciation. The presence of an end moraine, a drumlin, a fjord, or widespread glacial till would tell you that glaciers have shaped the landscape. An end moraine is a ridge of debris deposited at the terminus of a glacier, indicating a pause or stop in its advance. A drumlin is a streamlined hill composed of glacial till that indicates the direction of glacial movement, with its tapered end pointing in the direction the ice flowed. A fjord is a deep, narrow sea inlet with steep sides or cliffs, created by a glacier scouring a valley and then being inundated by ocean water. Glacial till is unsorted sediment left behind after a glacier has melted.
