Question

1. a forest fire is burning near a cold lake. which image correctly shows the convection cell that would develop? image with a, b, c, d ⓒ image a ⓒ image b ⓒ image c ⓒ image d

Explanation:

To solve this, we analyze convection cell formation near a fire (heat source):

Step 1: Recall Convection Principles

Convection cells involve warm air rising (near the fire, air is heated), then moving horizontally away from the heat, cooling, and sinking, before moving back toward the heat source.

Step 2: Analyze Each Image

• Image A: Arrows show air moving toward the fire at the bottom, rising, moving away, then sinking. But the bottom arrow (toward fire) and top arrow (away) should align with rising at the fire. Wait, no—let’s re-examine.
• Image B: Air rises at the fire (upward arrow), moves horizontally away from the fire (right arrow), then sinks (downward arrow), and moves back toward the fire (left arrow). This matches the convection cycle: warm air rises, moves away, cools/sinks, then returns to the heat source.
• Image C: Arrows are reversed (sinking at the fire, which is incorrect—fire heats air, so air should rise there).
• Image D: Arrows are chaotic (e.g., downward at the fire, which contradicts rising warm air).

Only Image B follows the convection cell pattern: warm air rises at the fire, moves horizontally away, cools and sinks, then flows back toward the fire to be heated again.

Answer:

Image B
