Convection Currents Diagram - Heat Transfer Visualization #66917 (License: Personal Use)

This schematic illustrates convection in fluids: a flame at the base heats the surrounding medium, causing it to expand, become less dense, and rise (indicated by yellow arrows). As the warm fluid reaches the top, it cools, becomes denser, and sinks (blue arrows), forming two symmetrical convection cells. Red arrows at the center show horizontal flow where rising and sinking streams meet.

Used in educational materials (e.g., middle/high school science, introductory physics) to explain heat transfer via convection; supports lessons on weather systems, ocean currents, or mantle dynamics. Matches user intent for visual learning and conceptual clarity.
