Answer:
The floodplains provided fertile soil for growing crops.
Explanation:
In the fertile crescent, the most important floodplain is that of Mesopotamia, between the rivers Tigris and Euphrates.
This area of the world is not only where agriculture was first attested, but also the region where the first human civilization emerged: Sumer.
And the floodplain was crucial for this. The rivers flooded their banks with nutrients that were carried in sediments. These nutrients made the soil more fertile, allowing for easier and more productive agriculture, which produced the necessary food surpluses that are required for the development of early civilization.
California or Idaho, it depends on what states you are calling western states
Well, I am a Muslim, (a person in the religion of Islam), so I could answer this very easily.
Why it's so important to North African countries is because North African Countries are closer to the middle east; the "base" or "home" of Islam.
Why you may ask is it our base/home?
Well that's the area of land our religion was founded in, by our Prophet Muhammad (May peace and blessings be upon him).
So, since North African Countries are very close to the middle east, (they actually used to be part of the middle east; in fact, all countries were actually one full piece of land called "Pangaea" until Earth's tectonic plates divided it into multiple pieces of land), they felt as if they would interpret many of the middle east's customs, religion, tradition, culture, and basically their lifestyle.
This is why it's important :)
