Which outcome relating to arid zones occurs from Hadley cell subsidence?

💡 Explanation

Deserts form around 30 degrees latitude because descending air in Hadley cells is compressed and warms, increasing its capacity to hold moisture via adiabatic compression. This suppresses precipitation therefore creating arid conditions rather than rainfall-dominated biomes expected otherwise.
