WORLD CIVILIZATION

Detailed explanation-1: -The materials used to build a Mesopotamian house were similar but not exact as those used today: reeds, stone, wood, ashlar, mud brick, mud plaster and wooden doors, which were all naturally available around the city, although wood was not common in some cities of Sumer.

Detailed explanation-2: -Because the area lacked wood from forests, minerals, or natural stone, the Mesopotamians made mud bricks from the soil in the fertile valley. Some of the massive ziggurats made from mud bricks still stand today, 5, 000 years old.

Detailed explanation-3: -The walls were made of mud bricks that were baked in the sun until they were hard. The Sumerians also dug moats outside the city walls to prevent enemies from entering the city.
