Frozen water (ice) has less density than liquid water. how does this property of water affect life on earth? ice floats on the surface, sustaining life at the bottom of lakes and oceans. ice floats on the surface, animals migrate over lakes and bays. ice floats on the surface, maintaining sub–zero temperatures at the bottom of lakes and oceans.

How does upwelling affect coastal fisheries? upwelling damages nutrient supplies at coastal fisheries as the warm, nutrient-rich surface water is replaced by nutrient-poor, cold water. upwelling damages nutrient supplies at coastal fisheries as the cold, nutrient-rich surface water is replaced by nutrient-poor, warm water. upwelling improves the nutrient supply at coastal fisheries as the warm, nutrient-rich surface water replaces the nutrient-poor, cold water. upwelling improves the nutrient supply at coastal fisheries as cold, nutrient-rich water replaces the warm, nutrient-poor surface water.
