What landform do you want after a large stratovolcano erodes away, leaving behind an intrusive igenous magma body exposed at the surface

volcanic neck

Explanation:

The volcanic neck is formed when lava solidifies inside the volcano. just the same way clay or cement solidifies inside a mold.

When the large external surface of the volcano erodes away, the volcanic neck will be left standing because it is a harder rock that the volcanic body. This can be seen as the "intrusive igneous magma" that is left behind after the surface is removed

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.

the climate of each region is different from one another.
