Explain how land and sea breeze modify temperature.

If the area you are in is warm then the breeze is light wind, so it wouldn't be cold.
If you were by the beach in a warm area, sea breeze is colder than a normal breeze so it would be between warm and cold. Hope this helps

Land breeze: During the evening hours, a land breeze occurs because the ground cools rapidly during this time but the ocean remains warm.  At night, warm air rises over the sea, creating a low - pressure area.  The air sinks over the land creating a high - pressure area. The land breeze then flows from land to sea.

Sea Breeze: During the daytime, the land heats up faster then the ocean. Rising warm air moves out over the sea, cools, and sinks toward the sea surface. The cooling, sinking air mass creates a high - pressure area. The air flows from high - to low - pressure areas.
