Convection Currents Explained - Visual Science Demonstration #3683805 (License: Personal Use)

This educational illustration depicts a beaker of water heated from below by a Bunsen burner, generating visible convection currents-warm water rises (red arrow), cools at the surface, then descends (blue arrow). Bubbles indicate boiling onset, and the setup includes a clamp stand for stability. The labeled arrows and color coding clarify the cyclical motion driven by density differences due to temperature gradients.

Used in physics and earth science curricula to demonstrate heat transfer mechanisms; commonly appears in textbooks, online lessons, and classroom slides for teaching fluid dynamics and atmospheric/oceanic circulation.
