The deserts stretching across northern Africa and Eurasia lie beneath the descending branch of the Hadley cell (20°–30° N), where high-pressure, dry air suppresses cloud formation and rainfall—explaining their aridity (statement 1). These coasts are influenced by cold, not warm, currents such as the Canary and Benguela, so statement 2 is incorrect.
