Answer:
North Africa is mostly desert. But the ancient Egyptians found that they could grow crops by irrigation ditches from the Nile River
Explanation:
The correct answer is oceanic; subduction
The lithosphere layer is above the asthenosphere, a layer that presents the rocks in a more pasty state, due to the high temperatures present inside the planet. The meeting zone between the lithosphere and the asthenosphere has an isotherm, that is, a constant temperature, which is approximately 1,200ºC. Thus, everything above this point of contact has sufficient temperatures to make the rocks remain rigid.
(not 100% sure) but the first thing that comes to mind for me is the Egyptian religion.
C. who should be Muhammad's successor
Explanation:
The two sects disagree over who should be the Khalifa and by extension the ruler of the caliphate after the death of prophet Muhammad. T<u>he Sunnis were the ones that lobbied for the four consecutive Khalifas starting with Abu Bakr while the Shias firmly advocated for Ali ibn e Talib.</u>
This case was the real divide that formed the two most important sects of Islam which is the Sunni and the shia.
