WebMar 14, 2024 · Examples of Convection Currents. Let us discuss a few examples of a convection current. Campfires– The convection currents heat our hands. That’s why we feel hot around the campfire. Convection currents are present in the air– A typical example of a convection current is the warm air that rises towards the ceiling of a house since the ... WebMar 1, 2024 · Earth's heat budget, which measures the flow of thermal energy from the core to the atmosphere, is dominated by mantle convection. Earth’s heat budget drives most …
WebConvection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid … WebConvection can be observed in many ways. This article will focus on how convection currents are created in the Earth's atmosphere and describe three distinct atmospheric convection cells.
