Question

1. what effect does sea level rise have on coastal areas?

a. it leads to increased flooding and erosion
b. it enhances coral reef growth near islands
c. it stabilizes saltwater levels in rivers
d. it reduces wave heights during storms

Explanation:

To determine the effect of sea level rise on coastal areas, we analyze each option:

• Option a: Sea level rise causes higher water levels, leading to more frequent and severe flooding and increased erosion of coastlines as waves and tides impact shorelines more intensely.
• Option b: Sea level rise often stresses coral reefs due to increased water depth, temperature changes, and sedimentation, rather than enhancing growth.
• Option c: Sea level rise causes saltwater intrusion into rivers, destabilizing freshwater - saltwater balances, not stabilizing them.
• Option d: Sea level rise does not reduce wave heights during storms; in fact, higher sea levels can exacerbate storm - surge related wave impacts.

Answer:

a. It leads to increased flooding and erosion
