During a land breeze, which of the following best describes the movement of air?

• A. Warm air moves from the sea toward the land during the day.
• B. Cool air rises over the sea and sinks over the land.
• C. Warm air moves from the land toward the sea during the day.
• D. Cool air moves from the land toward the sea at night.

Answer: (D)

Verified step by step guidance

1. Understand the concept of land breeze: A land breeze occurs at night when the land cools down faster than the sea due to differences in heat capacity between land and water.
2. Recognize the temperature differences: At night, the land becomes cooler than the sea, while the sea retains more heat and remains relatively warmer.
3. Analyze air movement: Warm air over the sea rises because it is less dense, creating a low-pressure area. Cooler air from the land, which is denser, moves toward the sea to replace the rising warm air.
4. Identify the correct description: The movement of air during a land breeze is characterized by cool air moving from the land toward the sea at night.
5. Relate this to convection: This process is driven by convection currents, where warm air rises and cooler air sinks, creating a cycle of air movement between the land and sea.
