when the nile river flooded every june, what was left behind when the water receded that allowed the civilization to flourish?\n\n○ an abundance of sea life\n○ stable land suitable for building\n○ vast mineral deposits\n○ a rich layer of soil
Answer
Brief Explanations:
The Nile River's annual flooding in June brought nutrient - rich silt from upstream. When the water receded, this silt formed a rich layer of soil, which was extremely fertile and ideal for agriculture, enabling the civilization to flourish. Sea life is not related to the Nile's flood deposits, the land after flood isn't mainly for building initially (it's for farming), and mineral deposits aren't the main thing left by the Nile's flood.
Answer:
D. a rich layer of soil
