Passat circulation — role?
Drives tropical/subtropical climate patterns.
Desert types — main features?
Sand (erg), gravel (reg), rock (hamada).
Oasis layers — concept?
Vertical vegetation structure (Stockwerkbau).
Salinization — cause?
Improper irrigation leading to salt buildup.
Desert flora adaptations?
Water conservation, drought tolerance.
Trade winds — origin?
From subtropical high-pressure zones.
ITC shift — effect?
Alters rainfall, influences savanna types.
Hadley Cell — function?
Circulates warm air, forms deserts.
Artificial oasis — creation?
By human irrigation efforts.
Desert fauna adaptations?
Behavioral, morphological, physiological for survival.
