Sources of energy in hot desert environments: insolation, winds, runoff
Hot deserts get their energy from three sources: intense sunlight, wind, and occasional fast-moving water. These three forces drive every process that shapes desert landscapes.
Real World
In Wadi Rum, Jordan, flash floods carrying abrasive sediment carved narrow slot canyons in sandstone within hours, demonstrating how episodic runoff energy can reshape desert landscapes far more than months of steady wind.
Exam Focus
Rank energy sources by geomorphic impact for the specific landform asked about — avoid listing all three without linking each to a process.
