The following statements correctly describe how geography has affected settlement patterns in North Africa:
- Settlement is concentrated along the Mediterranean coast and Nile River Valley.
- Densely populated areas are found near water sources or areas with regular precipitation.
- Areas with a good climate for farming attract higher populations.
These responses reflect the significant influence of geography, including the availability of water resources, favorable climates, and fertile land, on population distribution and settlement patterns in North Africa.
The other options about populations being highest near tropical wet climate zones and rain forests supporting the largest populations do not accurately represent North Africa, as the region is characterized by arid and semi-arid climates rather than tropical wet climates or rain forests.
