What were the differences between the natural conditions in Egypt and Greece?

Ancient Egypt was located on a flat area where the great Nile River flowed. The climate was hot, although the floods of the river made it possible to develop agriculture and harvest crops: wheat, barley, etc. Also, the Egyptians were engaged in the withdrawal of cattle. If we take Greece, then the climate there was milder, however, the mountainous terrain did not make it possible to sow large fields. Most often, the Greek economy was located in small valleys, where vineyards grew and sheep were grazed.
