How did mining lead to the establishment of new towns in the west?

Mining settlements sometimes developed into permanent towns and cities.

Explanation:

Beginning with the California Gold Rush of 1849, several other mining areas were discovered in the West.

These new boomtowns provided the crucial material for the eastern Industrial Revolution: gold, silver, zinc, copper, and lead.

Each mining area needed a town. Although most of them would disappear after the mines were emptied, leaving behind ghost towns, some of them prospered into big cities.

the correct answer option is: weapons.

explanation:

tensions rose as the two opposing superpowers competed for 'weapons'.

referring to the cold war (1945-1991), the two superpowers, usa and ussr, experienced a phase of struggle and conflict with each other. these two superpowers considered each other as a threat to their survival and thus opted for policies to strengthen their positions.

the two superpowers never went to war with each other directly but competed for weapons to preserve their positions.
