What causes the circulation of air in the atmosphere?

• Air in the atmosphere is heated by the sun and sinks to the ground.
• The ground is heated by the sun and then heats the air, causing the air to rise.
• Air loses heat to the ground and then rises upward to obtain more energy.
• The sun heats the clouds which forces the cooler air to move away and sink.
