Question

22 why does a sea breeze occur on the coast during a summer afternoon? the temperature of the land and sea are identical, so no breeze occurs. the sea heats up faster than land, causing air to move from land to sea. the sea retains heat longer into the night, causing air to move from the sea to land. land heats up faster than the sea, causing air to move from the sea to land.

Explanation:

To determine why a sea breeze occurs in summer afternoons, we analyze the heat - capacity differences between land and sea. Land has a lower heat capacity than the sea, meaning it heats up faster during the day (like a summer afternoon). When the land heats up, the air above it warms, becomes less dense, and rises. This creates a low - pressure area over the land. Meanwhile, the sea heats up more slowly, so the air above the sea is relatively cooler and denser, creating a high - pressure area. Air moves from high - pressure (sea) to low - pressure (land) areas, which is the sea breeze.

Let's analyze each option:

• Option 1 (Land heats up faster than the sea, causing air to move from the sea to land): This matches our understanding. The land's faster heating creates a pressure difference that makes air move from sea (high pressure) to land (low pressure).
• Option 2 (The sea retains heat longer into the night, causing air to move from the sea to land): This describes a land - breeze situation (which occurs at night), not a sea - breeze (which occurs during the day), so it's incorrect.
• Option 3 (The sea heats up faster than land, causing air to move from land to sea): This is the opposite of the actual heat - up rates (land heats up faster), so it's wrong.
• Option 4 (The temperature of the land and sea are identical, so no breeze occurs): Since land and sea have different heat capacities, their temperatures aren't identical during the day, and a breeze does occur, so this is incorrect.

Answer:

A. Land heats up faster than the sea, causing air to move from the sea to land
