Which mechanism causes the intertropical convergence zone (ITCZ) shift seasonally?

💡 Explanation

Seasonal shifts in the ITCZ are caused by changes in the Earth's axial tilt changing solar radiation received at different latitudes which subsequently affects the Hadley cells circulation patterns. Therefore, axial tilt results in this shift, rather than salinity volcanic activity or CO2 concentration influences, which exert different global mechanisms.
