Which of the following describes how air moves in a convection current? (6.4c)
Air in the atmosphere is heated by the Sun and sinks to the ground.
Ground is heated by Sun & then heats the air, causing warm air to rise.
Air loses heat to the ground and then rises upward to get more energy.
The sun heats the clouds which forces the cooler air to move away and sink.
