the capital of iran is Tehran or Teheran.
Surface of the Earth: Most of the Earth's surface (70%) is covered with water, and the remaining 30% is taken up by the seven continental landmasses. However, underneath the water that fills the oceans, and the dirt and plants that cover the continents, the Earth's surface layer is made of rock.
The air masses that would be associated with cold, wet conditions would have to be A and D.
Hope this helps!!
