30 POINTS HELP ASAP PLEASE Air in the atmosphere continuously moves by convection. At the equator, air rises; at the poles, air sinks. This occurs because— the air at the equator is warmer and less dense and the air at the poles is cooler and more dense
the air at the equator is warmer and less dense and the air at the poles is cooler and more dense

the air at the equator is cooler and more dense and the air at the poles is warmer and less dense
the air at the equator is cooler and more dense and the air at the poles is warmer and less dense
