Exploring the Dynamics of Convection

The video explains convection, a heat transfer process involving fluid movement. It starts with boiling water as an example, then expands to atmospheric convection, highlighting Hadley cells and the Earth's tilt. Oceanic convection is discussed, focusing on equatorial and polar water movement. The video also covers mantle convection, proposing it as a driving force for plate tectonics. The conclusion encourages viewers to engage with the channel.

What is convection?

• Heat transfer through radiation
