Answer:
Maps and globes are drawn to scale and use symbols to represent topography and other features on Earth's surface. Grid lines on maps and globes are often used, with lines curving because the Earth is a sphere. The baselines for measuring distance on Earth are the equator and the Prime Meridian. Satellites are also often used as a mean to graph.
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
