Answer:
It took climate change, fertile river valleys, domestication of crops and animals so that the hunter-gatherers became sedentary farmers.
Explanation:
Initially, all humans were hunter-gatherers. This was due to multiple reasons, with one the biggest one probably being the climate which was not enabling good conditions for the hunter-gatherers to transform their lifestyle. All other conditions needed were stopped because of the climate conditions, so humans had to do what they could to survive in those conditions.
About 10 years ago though the bad climate conditions ended, or rather the Ice Age ended. This resulted in a much warmer climate, which in turn created much more water bodies like rivers and lakes, much more vegetation, and they contributed to the creation of much more fertile soil.
With these conditions in place, the humans quickly saw that there is huge potential in some plants and animals, so they started to farm them, select the ones with the best characteristics, and gradually producing enough food for themselves. With the food problem solved, humans didn't have the need to wonder around all the time, so they started abandoning the hunter-gatherer lifestyle and started settling in one place.
Could you please put a picture of the text? But i’m pretty sure they had a big hurricane and because the city is basically bowl- shaped, the water couldn’t really get out. There was so much water coming in that the levees broke and that’s why there was so much flooding.
Oceanic and continental plates are colliding.
Explanation:
On the image, we can see an oceanic plate on the left, and a continental plate on the right, moving toward each other and colliding. Because the two plates have different densities, thickness, and elevation, one of the subducts below the other, that being the oceanic plate. As the oceanic plate subducts below the continental plate, it gradually moves down in the mantle layer, getting melted, recycled, and maybe the same material be pushed toward the surface again.
On the plate boundary, convergent in this case, there is intense geological activity. Magma manages to rise through the cracks and gaps, and it forms volcanoes, creating a continental volcanic arc. Also, there are lot of earthquakes at such boundaries, as there is constant adjustment of the crust.
Such boundaries can be found between the:
- Pacific and North American plates
- Pacific and Eurasian plates
- Pacific and Australian plates
- Pacific and Philippine plates
- Nazca and South American plates
- Cocos and North American plate
