Final answer:
Convection currents are the movement of fluids as a result of temperature differences. They can be observed in various natural phenomena, such as ocean currents and atmospheric circulation. Convection currents also play a role in heat transfer within the Sun.
Step-by-step explanation:
Convection currents refer to the movement of fluids as a result of temperature differences. In this process, warmer fluids rise while cooler fluids sink, transferring energy in the process.
For example, when you heat soup on a stove, the warmer soup near the bottom rises while the cooler soup near the top sinks. This creates a circular flow of fluids.
In nature, convection currents play a role in various phenomena such as ocean currents, atmospheric circulation, and even the movement of heat within the Sun.
