  1. Chapter 21: Harsh and Arid Lands Section 2 Climate and Vegetation

  2. Variety in Arid Lands • Southwest Asia is extremely arid. The vegetation and animals living in the desert can survive on little water and in extreme temperatures. A camel caravan in Afghanistan

  3. Variety in Arid Lands • In other parts of the region, a Mediterranean climate prevails, making the land green and lush for at least part of the year. Coast of Lebanon

  4. Deserts Limit Movement • The most famous desert in the region is the Rub al-Khali, also known as the Empty Quarter. During the summer, the temperature on the surface of the sand often exceeds 186°F.

  5. Deserts Limit Movement • Next to this desert is the An-Nafud Desert. Severe sandstorms and brutal heat make this desert a barrier to travel across the Arabian Peninsula.

  6. Salt Deserts • In Iran, the high mountains block rain, and dry winds increase evaporation. So when winds evaporate the moisture in the soil, chemical salts remain, creating a salt flat. A hiker resting on a salt flat in Iran

  7. Semiarid Lands • On the fringes of the desert are regions with a semiarid climate. These regions offer good pasture lands for grazing animals. In Turkey, large herds of mohair goats graze on these lands. Their hair, and fabrics made from it, are among Turkey’s exports. Angora goats in Turkey

  8. Well-Watered Coast Lands • Southwest Asia does have some areas with adequate rainfall. Along the Mediterranean coast and across most of Turkey, hot summers and rainy winters create a good climate for growing citrus fruits, olives, and vegetables.
