A geographer wants to learn more about the movement of people around the world. She starts by gathering data on
the number of people who relocated from one country to
another over the past 30 years. She then begins searching
for patterns that might explain why people chose to find
new homes during that period.
The geographer in the passage is focused on
A. human-environment interaction
B. meteorology
C. cartography
D. human geography

The geographer in the passage is focused on human geography.

Explanation:

Human geography is part of geography that focuses on humans, their activities in the environment (both natural and anthropogenic), their characteristics, movements, as well as the reasons for any of them. Not to be mistaken though, despite humans being in the center of this part of geography, everything is connected with physical geography in one way or another, thus there are a lot of connections between the two major branches of geography.

In this case, the geographer is gathering data about the migration of people from one country to another in a given time period, as well as looking for patterns in that time period to find out why is that the case. Basically, the geographer is researching human activity, from one human-based creation to another, but all of that happening in the physical sphere, thus it is of interest to human geography, but as mentioned it is easy to see that there is a connection with the other part of geography as well.

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.
