What geographic feature helped Mesopotamia and Egypt expand? Explain why.

Tigris and Euphrates

Explanation:Irrigation enabled Mesopotamia to extend waters of the river into land of farming. This led to progress in engineering such as canals, dams, reservoirs, sewers and aqueducts.

Watered by irrigation, they have become very productive farms, capable of supporting huge populations. Between BCE 6000 and BCE 4000, the population in southern Mesopotamia increased extremely greatly over two thousand years. New inventions appeared at an accelerated rate of development.

Mesopotamia refers to the region flowing from the Taurus Mountains between the Euphrates and the Tigris rivers. The region's climate is semi-arid and the wide desert in the North gives way to a 5,800 square meter marshland, lagoons, mud flats and the southern banks of reed.
