General KnowledgeGeography
- A1 only
- B2 only
- CBoth 1 and 2
- DNeither 1 nor 2
Explanation
Alpine glaciers scour their valleys into broad U-shaped glacial troughs, stripping away soil, regolith and sediment — statement 1 is correct. When sea level stands below the floor of such a trough (or the trough is drowned by the sea), it forms a fjord — statement 2 is correct. Hence both.
