Cradles of Civilization: Why Rivers?

CASE BRIEF: Mesopotamia, Egypt, the Indus Valley, and China all rose along major rivers. That is not a coincidence.

TASK: Compare the four river-valley civilizations using maps and irrigation evidence to explain why rivers were essential to early civilization.

EVIDENCE: Map of the Fertile Crescent and Nile floodplain - Description of Indus Valley drainage/sewage systems - Diagram of Chinese Yellow River flood cycles

ANALYZE: What specific problem did each river solve for early farmers? What risks did rivers also create? Why didn't civilization arise first in resource-poor deserts?

BUILD A CLAIM: Explain why river valleys — rather than other geographies — produced the world's first civilizations.

RUBRIC: Compares at least 3 of the 4 civilizations - Cites specific geographic evidence - Addresses both benefits and risks of river life
