Hi there,
The climate in Saudi Arabia, Iraq, and Iran is mainly Desert.
Those places are located around the Middle East area and the Middle East is covered in dry hot sand so it'll make sense that Saudi Arabia, Iraq and Iran is a desert. 
Hope this helped :)
Have a great day

As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere. Trees provide many benefits to us, every day.
