What is the relationship between upwelling zones and sediment composition?

• A. Upwelling zones contain only inorganic sediments
• B. Upwelling zones often have high nutrient availability, leading to diverse and productive sediments
• C. Upwelling zones suppress sediment formation
• D. Upwelling zones are generally low in biodiversity

Answer: (B)

Upwelling zones are areas in the ocean where cold, nutrient-rich water rises to the surface. This process enhances nutrient availability, which fuels primary productivity and leads to the growth of phytoplankton and other marine organisms. As these organisms die, their remains contribute to the sediment composition in these regions. Consequently, upwelling zones typically feature a diverse array of organic sediments, reflecting the high levels of biological activity and productivity. This rich nutrient environment not only supports a wide variety of marine life but also results in distinct sediment types that are different from those found in downwelling or nutrient-poor areas. This dynamic interaction between nutrient availability and sediment composition is why the relationship in question is accurately depicted by the chosen answer.
