Why is convection more important than conduction in the troposphere? halp lol

The faster the particles are moving, the more energy they have. Why is convection more important than conduction in the troposphere? The air doesn't conduct heat well so only the first few meters of the troposphere are heated with conduction

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
