Question

part c
recall that geographical features __________ to the formation of the earliest known civilization in sumer.
match the causes with the geographical features and effects that led to civilizations developing in
mesopotamia.

feature	cause	effect
semiarid climate		- forced the development of irrigation<br>- created a need for trade and commerce
deserts		- acted as a barrier to intruders<br>- enabled large regions to unite under common goals
mountains		- enabled large regions to unite under common goals<br>- brought more water and fertile soil to the region
seas	- food source<br>- transportation	- provided resources<br>- allowed the exchange of ideas and culture<br>- provided food

Explanation:

Each geographical feature is matched to its logical cause (why it impacted civilization) and effect (the resulting change for Sumerian/Mesopotamian civilization) based on historical and geographic context:

1. Rivers: Their core traits are bringing water/fertile soil, enabling food production and transport; effects are crop water and trade support.
2. Semiarid climate: The lack of consistent rainfall is the root cause, driving irrigation and trade needs.
3. Deserts: Their harsh, uncrossable terrain is the cause, acting as a defense barrier.
4. Mountains: They block rainfall and create isolated areas, forcing regional unity and carrying silt/water to lowlands.
5. Seas: They provide food and transport routes, leading to resource access, cultural exchange, and food supply.

Answer:

Feature	Cause	Effect
semiarid climate	• limited consistent rainfall in the region	• forced the development of irrigation<br>• created a need for trade and commerce
deserts	• harsh, impassible terrain	• acted as a barrier to intruders
mountains	• block consistent rainfall<br>• create isolated sub-regions	• enabled large regions to unite under common goals<br>• brought more water and fertile soil to the region
seas	• food source<br>• transportation	• provided resources<br>• allowed the exchange of ideas and culture<br>• provided food

Additionally, the opening blank: contributed
