What is the primary geomorphological term for the low-lying, salt-encrusted coastal and inland mudflats widely distributed across Kuwait's shoreline and Bubiyan Island?
Answer and explanation
Correct answer: C. Sabkha
- Step 1: A 'sabkha' is a supratidal or inland flat surface of silt, clay, and sand encrusted with soluble evaporite minerals (halite, gypsum, anhydrite).
- Step 2: Coastal sabkhas dominate the intertidal zones around Bubiyan Island, Warbah Island, and the southern Kuwaiti coastline.
- Step 3: Sabkhas are characterized by high salinity, periodic waterlogging, and specialized halophytic vegetation.
Answer
Sabkha.
Why not the others: 'Erg' is a vast desert sea of shifting sand dunes; 'Wadi' is a dry river valley; 'Barchan' is a crescent-shaped sand dune.
