What biological and environmental property does water's high specific heat provide within a water-cycle ecosystem?

Answer and explanation

Correct answer: It provides thermal stability

Correct answer: B, thermal stability. Specific heat is the amount of heat needed to raise the temperature of a unit mass of a substance by one degree. Water has a high specific heat, so it can absorb or release substantial heat while its temperature changes comparatively slowly. This moderates temperature changes in ponds, lakes, oceans, organisms, and nearby environments. A high specific heat does not make water evaporate instantly; evaporation depends on energy, vapour pressure, and other conditions. C water's weight is not reduced by this property. D acidity is determined by chemical composition and hydrogen-ion concentration, not specific heat. Memory cue: high specific heat acts like a thermal buffer.
