← GeographyWhich global precipitation effect is caused by the intertropical convergence zone (ITCZ)?
A)Seasonal arid land expansion
B)Equatorial rainforest development✓
C)Polar desert intensification
D)Temperate grassland decline
💡 Explanation
When insolation reaches the equator, intense solar heating warms the air, causing strong convection and uplift which forms the persistent low pressure of the ITCZ. Therefore equatorial rainforest development results due to consistent high precipitation, rather than arid lands, polar deserts, or declining grasslands influenced by other latitude-dependent climate dynamics.
