Final answer:
Boomtowns show that physical characteristics of the environment influence population distribution, settlement patterns, and economic activities.
Step-by-step explanation:
Boomtowns are characterized by their rapid and significant population growth, settlement patterns, and economic activities. These characteristics are influenced by the physical characteristics of the environment.
For example, the discovery of gold or other valuable resources in a specific location can lead to a boomtown, as people flock to the area in search of wealth and economic opportunities.
The physical geography of the area, such as the presence of rivers or mountains, can also impact the distribution and size of settlements in a boomtown.
