Geography. Iraq, a triangle of mountains, desert, and fertile river valley, is bounded on the east by Iran, on the north by Turkey, on the west by Syria and Jordan, and on the south by Saudi Arabia and Kuwait.rom earliest times Iraq was known as Mesopotamiaâthe land between the riversâfor it embraces a large part of the alluvial plains of the Tigris and Euphrates rivers.
The main rivers in the Fertile Crescent are  the Euphrates River, the Tigris River, and the Jordan River. The Fertile Crescent included the arable river valleys that ran from Africa to the Persian Gulf in Western Asia. The Fertile Crescent begins in what is now southern Iraq where the Tigris and Euphrates rivers empty into the Persian Gulf. It extends north along with the rivers, turns â¦ westward in what was ancient Assyria, and then turns back south in what is modern Syria.
