The correct answer is:<\/p>\n\n\n\n

A. Water has a high specific heat capacity<\/strong><\/p>\n\n\n\n

Explanation:<\/strong><\/p>\n\n\n\n

Water’s high specific heat capacity plays a crucial role in moderating temperatures in coastal areas. Specific heat capacity is a measure of the amount of heat energy required to raise the temperature of a substance by one degree Celsius. Water has a relatively high specific heat capacity of about 4.18 J\/g\u00b0C. This means that water can absorb or release a large amount of heat with only a small change in its own temperature.<\/p>\n\n\n\n

In coastal areas, the ocean or large bodies of water act as a thermal buffer. During the day, when the sun heats up the land, the water absorbs much of the heat without experiencing a significant increase in temperature. This is because the high specific heat capacity of water allows it to store and gradually release heat. Conversely, at night, when temperatures drop, the water releases the heat it stored during the day, which helps to keep the coastal areas warmer than inland regions.<\/p>\n\n\n\n

This moderating effect of water helps to reduce the temperature extremes between day and night. Inland areas, which are not near large bodies of water, do not benefit from this thermal buffering effect. As a result, they experience more pronounced temperature fluctuations, with hotter days and colder nights compared to coastal regions.<\/p>\n\n\n\n
