Final answer:
The latent heat of fusion of water helps to moderate air temperatures near large bodies of water, preventing rapid temperature drops below 0°C due to water releasing heat as it freezes. Water's high specific heat allows it to absorb and release significant amounts of heat, impacting coastal climates. Ocean currents also distribute this heat globally, contributing to milder maritime climates.
Step-by-step explanation:
The role of the latent heat of fusion of water is crucial in moderating air temperatures, particularly near large bodies of water. When water freezes, it releases a significant amount of heat, which can prevent air temperatures from falling rapidly below 0°C. This property is one reason why coastal areas generally have milder climates compared to inland areas. Additionally, water's high specific heat means that it can absorb a lot of heat before its temperature rises significantly, which also aids in cooling the surrounding air on hot days and warming it on cool days.
Ocean currents further play a vital role in distributing this heat across different parts of the world. This is because oceans collect vast amounts of solar energy, especially around the equator, and transport it through currents over thousands of miles, affecting the climate of different regions. Coastal areas, therefore, experience less extreme temperature variations both throughout the day and across seasons, compared to inland areas.
