8 They built a majority of their settlements on the floodplain, while they usually buried their dead in the desert margins beyond the a result of these decisions, most settlement sites have been covered by silt or washed away. There are few settlement sites for archaeologists to study, but there are many burial sites. Also, the river valley was narrower in ancient times (more than 7,000 years ago), consequently some burial sites dating to those times have been lost. 10. Why do you think the people of ancient Upper Egypt built settlements where they did? Explain your answer. 11. Why do you think the people of ancient Upper Egypt buried their dead where they did? Explain your answer. 12. Why do you think there are many burial sites of ancient Upper Egypt for archaeologists to study? Explain your answer.

A stream s load, discharge, and speed will determine whether or not it eventually becomes a river. 15. The Mississippi River Delta is sediment deposited on land at the mouth of the river. 16. Evaporation and transpiration are part of the water cycle.
