The video explains convection, a process where heat is transferred through gases or liquids by the movement of matter from warm to cold areas. It provides examples from daily life, such as warming hands over a heater and hot air balloons. The mechanism of convection is detailed, highlighting how heated substances expand and rise due to decreased density. An experiment demonstrates convection currents using smoke. The video also covers convection in Earth's mantle, driving plate tectonics and shaping landforms. Finally, it discusses convection's influence on weather, climate, and ocean currents, emphasizing its vital role in life on Earth.
