Step 1I'll solve this problem by identifying three distinct situations where convection occurs, explaining the mechanism in each case.
Step 2: Atmospheric Convection
- Mechanism: $$T_{surface} \uparrow \rightarrow \rho_{air} \downarrow \rightarrow \text{Warm air rises}
In the Earth's atmosphere, convection occurs when the sun heats the ground, causing air near the surface to warm up and become less dense. This warm air rises, creating vertical air currents. - Example: Formation of cumulus clouds on a hot day
Final Answer
1. Atmospheric air movement 2. Ocean current circulation 3. Home heating system air circulation
