Four schematic diagrams are shown in Figure 8.1 to depict the direction of sea breeze. Which of them gives the correct direction?

Options

A.
B.
C.
D.

Explanation

To determine which schematic diagram correctly depicts the direction of a sea breeze, we can follow these steps:

### Step 1: Understand the Concept of Sea Breeze
- A sea breeze occurs due to the temperature difference between land and sea. During the day, the land heats up faster than the water, causing the air above the land to warm up, decrease in density, and rise.

### Step 2: Analyze the Behavior of Air
- As the warm air rises over the land, it creates a low-pressure area. To fill this low-pressure area, cooler, denser air from the sea moves in to replace it, creating a breeze from the sea towards the land.

### Step 3: Identify the Correct Diagram
- Look for a diagram that shows:
- Warm air rising from the land.
- Cool air coming in from the sea to replace the rising warm air.

### Step 4: Evaluate the Options
- Among the four options presented, identify which one shows:
- Arrows indicating warm air rising (upward) from the land.
- Arrows indicating cool air moving in (downward) from the sea.

### Step 5: Conclusion
- After analyzing the diagrams, the correct option that represents the sea breeze phenomenon is **Option C**, which shows warm air rising and cool air descending.
