2) Nomads also called Bedouins migrate through the desert raising sheep, goats, and camels and build tents and move on when their animals eat all the vegitation and then they move on to new land that contains new vegitation.

Oases

-Enviornment-

1) They occur were water has been trapped under ground.


2) Very in size, range from a few acres to large areas of land.


-Adaptations-

1) Nomads for a while have traveled from one oases to another in-search of water and vegitations.


2) Some Nomads gave up their wandering lifestyle to become sedentary, people that settle in one place, because they realized they could grow cropes at the oases.

The Coastal Plains

-Enviornment-

1) Range from 5 to 40 miles inland, it ends at a series of rocky cliffs.


2) The air is damp and moist and falls regulary and has a few natural harbors.


-Adaptations-

1) It is used for farming, farming communities thrived in Southern Arabia and people built deep wells, dams, and systems to irrigate the land.

Mountains

-Enviornment-

1) Arabia's mountains can range from 1,000 to 12,000 feet high and have a very different climate from the rest of the peninsula.


2) Moist winds from the Indian Ocean can bring as much as 20 inches of rain a year to the mountains and the rain and elevation help keep temperatures in the mountains cool.


-Adaptations-

1) People that live in the mountains in the Arabian region today live in a type of building or place of shelter.


2) The people that lived in the mountains would farm on the steep slopes by creating these step like terraces, or flat areas. Farmers also constructed dams and irrigation systems and stored extra rainfall in underground storage containers, leather bags, and hollowed-out trees.
