Answer:
Mesopotamia is a historic region located in West Asia within the Tigris-Euphrates river system. The word Mesopotamia means "between rivers" in Greek. The region was home to the ancient civilizations of Sumer, Assyria, and Babylonia.
The raw material that epitomizes Mesopotamian civilization is clay. The region bears the stamp of clay in its almost exclusively mud-brick architecture and in the number and variety of clay figurines and pottery artifacts. The earliest cities of southern Mesopotamia developed on the margins of a great marsh that provided an abundance of natural resources for construction (reed) and food (wild game and fish).
