Take a moment to think about how the Colorado River has evolved through time. Focus on how changing base level and stream incision created landforms, such as incised meanders and rincons, and arrange these events accordingly. Rank from oldest to youngest.

Explanation:

1. A stream moves parallel across its floodplain forming meanders, it ends at a lake which is also its base level.

2. Through crustal uplift, the base level of the stream becomes lowered and then the river starts to incise downwards.

3. This leads to the formation of incised meanders.

4. The cutoff of an incised meander leads to the formation of a rincon, this rincon shortens the river.

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.
