Final answer:
Coastal regions experience moderate temperatures because of the presence of the ocean, which acts as a moderator. Water in lakes or oceans has a high specific heat capacity, meaning it can absorb large quantities of heat without significantly changing its own temperature.
Step-by-step explanation:
Coastal regions experience moderate temperatures because of the presence of the ocean, which acts as a moderator. Water in lakes or oceans has a high specific heat capacity, meaning it can absorb large quantities of heat without significantly changing its own temperature. During hot days, the water absorbs heat from the air, preventing extreme temperatures in coastal areas. At night, the water releases the absorbed heat back into the air, further moderating the temperatures. Additionally, sea breezes contribute to the moderation of temperatures along coastlines. During the day, sea breezes occur when cool air moves from the ocean towards the land, providing a cooling effect. At night, the direction of the breezes reverses, with the air moving from the land towards the ocean.
