Just like a hot-air balloon lifting off the ground, blobs or "parcels" of hot air rise from the ground, carrying hot air skyward. This transfer of heat energy away from the ground by the vertical movement of air is called "free convection" or "natural convection." A hot air balloon rises because warmer air is less dense than cool air. Convection is the transfer of heat by movement of a fluid such as air. Convection happens in the atmosphere when air near the Earth's surface is heated. This heating causes the air to expand, become less dense than the surrounding air, and rise. The heated air is buoyant and transports heat energy upward. Convection in the atmosphere. Convection currents play a crucial role in weather patterns. They are responsible for the transfer of heat from the Earth's surface to the atmosphere, leading to the formation of clouds and precipitation. When the sun heats the Earth's surface, the air above it warms up and rises, creating a low-pressure area. Cooler air from surrounding areas rushes in to fill …Share this article. Earthquakes are the result of sudden movement along faults within the Earth.
