Answer: Water retains more heat than other materials, making coastal ecosystems warmer year-round.
Step-by-step explanation:
The water retains more heat than any other material because it has high specific heat. The specific heat can be define as the amount of heat required to raise the temperature of the substance of 1 gram to 1 degree Celsius. The water has high specific heat which indicates that it takes more heat energy to increase the temperature of water as compared to other substance.
It takes several hours to lower down the temperature of the water. The retain heat in water keeps the coastal ecosystem warm year round which favors the survival of the marine animals even in winters.
