Which statement is true in a convection cell? A. Air at the equator rises. B. Air at the poles rises. C. Air at the equator sinks. D. Air rises at both the poles and the equator.
The correct option is A. In the convection cell, cold air sinks at the poles because of their high pressure. As the air moves away from the poles along the earth surface, it begins to get warm and its pressure reduces. Convection cells are circular pattern of wind which are caused by the rising and sinking of wind.
