Final answer:
Glaciers are capable of forming lakes and valleys through their movements and erosive power, but not oceans or deserts.
Step-by-step explanation:
The movements of a glacier can lead to the formation of various landforms. When glaciers move, they erode the underlying rock and soil, carving out landforms as they go. Lakes and valleys are two such features that can be created by glacial movements. Glacial valleys, also known as U-shaped valleys, are formed as glaciers flow downhill and erode the surrounding landscape. Meanwhile, some types of glacial lakes, such as those formed when a glacial valley or trough along the coast becomes filled with water, can be a mixture of freshwater and seawater.
However, glaciers are not responsible for the formation of oceans or deserts, which are generated by various other geological and climatic processes. While glaciers do contribute to the formation of lakes, icebergs, and deserts in certain cases, these options are not directly formed by the movement of a glacier.
