What is the main cause of global convection currents: Deforestation O Uneven heating of the Earth by the Sun O The greenhouse effect O The increase in the number of cities

The main cause of global convection currents      is the uneven heating of the Earth by the sun.

Temperature difference between poles and equator create global convection current. Warm air in the equator become lighter and the pressure in the area drop while the cold air become heavier and sink results in the high pressure.

So, air moves from high pressure to low pressure.

Therefore, the main cause of global convection currents      is the uneven heating of the Earth by the sun.

♡ The Answer(s)! ♡  

✦ || The answer is, Uneven heating of the Earth by the sun!  

I apologize in advance if the answer is incorrect! ♡

♡ The Explanation(s)/Step-By-Step! ♡  

✦ || The light, warm pressure increases and the heavy, cold air sinks. The pressure differences causes air to move in the atmosphere. Eventually, the cold air sinks at the poles, and the air moves away while the temperature becomes warm, and the pressure drops!
