The correct answer is: U – shaped valley


    The correct option is c) U – shaped valley.
    • U-shaped valleys, also called trough valleys or glacial valleys, are the result of the freezing process. They are especially characteristic of mountain glaciers.
    • It has a characteristic U-shape in cross section, with steep, straight sides and a flat or rounded bottom.
    • Valley glaciers sometimes flow into the sea through narrow inlets (fjords). Steepen the surrounding walls as you would when carving a U-shaped valley.
    • For example, fjords have high, steep walls like glacial valleys, but their floors are below sea level and therefore flooded with seawater.
