How a convection current can enable a hawk to soar upward without flapping its wings?

A hawk can soar upward without flapping its wings by utilizing convection currents, which are upward streams of warm air. As the sun heats the Earth's surface, the warm air rises, creating these currents. By gliding into these rising columns of warm air, the hawk can gain altitude effortlessly, conserving energy while maintaining flight. This technique allows it to travel long distances while searching for prey.
