Question

how did the egyptians adapt to their environment, eventually create a fertile area, even though egypt borders the largest desert in the world?

Answer 1

I'd say the Egyptians adapted to their environment and created a fertile area due to The Nile River, unless this is a multiple choice question, in which case please provide those choices.

Answer 2

The Nile River helped make the soil fertile, they adapted to the area because each yearly flood left behind soil and silt, and they organized to plant their crops after the flood receded and eventually had an abundance of food when the flood came again.
Hope this helps!
