Question
The glaciers that filled the Sierra Nevadan valleys carved V-shapes into the rocks.
Solution
This statement seems to be incorrect. Glaciers, when they carve out valleys, typically leave a U-shaped valley rather than a V-shaped one. This is due to the fact that glaciers have the ability to erode the valley sides as well as the floor, leading to a wider and more rounded shape. V-shaped valleys are usually formed by river erosion, where the primary erosion is the valley floor, leading to a more pointed or 'V' shape.
