hi there!

question - how does mountainous terrain affect settlements in a region? choose all answers that are correct.

groups trade with each other regularly.

people travel from settlement to settlement.

why: since they travel to go trade or visit it may be harder to get there because of the mountainous terrain.

hope this : )

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.
