See the explanation down below.
Step-by-step explanation:
Populations may use rivers and lakes for a variety of resources that they may provide, such as food, materials, or even hygiene. Also, rivers and lakes were occasionally used for trade, so parts of a population may decide to live near a river to access those types of resources. Meanwhile, mountains can be used based on topography depending on where a population plans to live. Additionally, mountains are great for agriculture usage, as individuals can apply the method of contour plowing on their land. Deserts can be useful for other resources--cacti, animals--and can also be used as land for trade.
