Which of the following is false about Africa's watersheds? a. 95% of Egypt's population lives within Africa's major river basin b. Watersheds can be dangerous places to live because of the potential for flooding c. The first developments of African agriculture and urbanization began in great rift valleys d. Countries are often affected by another country's use of a river system because of how these areas may or may not be managed

True or False? If false, correct the statement so that it is true. The approximate location of the center of Africa is 05°N and 020°W.
False: 05°N and 020°E would be more accurate, since 020°W latitude runs through the Atlantic Ocean.

Which of the following is NOT an impact of climate on life forms? a. Dry Tropical - nutrient rich soil, loss in organic matter, rapidly lose nutrients when watered b. Rain Forest - minimum migration, life at many levels of ecosystem, animal pollinators c. Dry - Extreme adaptation to specific regions, insect pollination is common d. Wet/Dry - fosters migration, insect and wind pollination
a. Dry Tropical - nutrient rich soil, loss in organic matter, rapidly lose nutrients when watered This is an example of impact of climate on soils, not life forms
