Answer:
High heat capacity of large water bodies
Step-by-step explanation:
The water plays a significant role in maintaining a moderate type of climate near the coastal areas or around the large water bodies. This water bodies includes oceans, seas, large rivers and streams.
The water in these large water bodies has the high heat capacity, which means that the water in the oceans and seas undergoes heating and cooling at a much slower rate in comparison to the land areas. This is why it is able to maintain a moderate climate in the coastal areas.
