BIO NMDCAT Biological Importance of Water
nmdcat.online June 27, 2026

The property of water that explains why coastal areas have milder climates than inland areas is its

A. Low thermal conductivity, trapping heat at the coast
B. High specific heat, which moderates temperature swings
C. High transparency, reflecting solar radiation back into the atmosphere
D. Low density, causing cool air to sink over the ocean

📝 Explanation

The ocean absorbs vast amounts of solar heat during the day/summer with a small temperature rise and releases it slowly at night/winter. This large thermal inertia moderates the temperature of the adjacent land, keeping coastal areas cooler in summer and warmer in winter.
