Which risk increases when intense rainfall occurs in heavily fertilized agricultural areas?

💡 Explanation

Increased eutrophication arises due to nutrient runoff. Leaching transports excessive nitrates and phosphates into water bodies; because this excess boosts algal blooms and depletes oxygen, therefore aquatic life suffers, rather than localized desertification or increased soil salinity.

• Which landscape outcome prominently features preferential calcium carbonate dissolution?
• Which outcome results when persistent longshore drift encounters a natural coastal indentation?
• Which process initiates island arc formation when oceanic lithosphere converges?
• Which outcome commonly results when a river encounters differential erosion around a meander?
• Which risk increases when prolonged tephra burial inhibits plant growth?
