Where can convection currents be found in real-world examples, such as in the atmosphere, in the ocean, and in the Earth's mantle?

Convection currents can be found in real-world examples such as in the atmosphere, where they drive weather patterns and wind movements. In the ocean, convection currents play a role in the circulation of water and nutrient distribution. In the Earth's mantle, convection currents are responsible for the movement of tectonic plates and the formation of volcanic activity.
