The natural environment affected travel west because of a number of land masses that had to be traversed in order to reach the West Coast of the United States. The Mississippi River along with other major rivers like the Colorado (depending on the route taken) had to be crossed. In addition the Rocky Mountains posed a serious challenge in order to reach the Western United States. Beyond the Rockies there are also the Sierra Nevada mountains and deserts in Nevada, California, and Arizona that must be crossed to reach the West Coast. Therefore, there are a number of challenging environmental features that had to be crossed to reach the Western United States.
At its core, the field of economics tries to uncover basic universal facts. Like many sciences, economics has a strong foundation in mathematics, and it is developed by testing hypotheses. In many ways, economics can be viewed as a field of applied psychology. Understanding how humans behave in certain situations and respond to changes is essential for the field's development.
Unlike the so-called "hard sciences," however, many economic hypotheses are difficult to test. Economic systems are run by governments, and it is immoral to cause economic harm to individuals and populations. With its strong mathematical foundation and its reliance on human behavior, economics straddles the gap between more basic types of science and so-called "soft sciences" such as anthropology and sociology.
In the media and in politics, however, the scientific aspects of the field are often ignored. Politicians might discuss the morality of different economic policies, and they might make promises based on faulty economic premises. Because economic policies have such a dramatic effect on the lives of voters, politicians spend a considerable amount of time developing a message that influences voters.

In the Co-operative federalism, the state and federal governments are seen to have equal share of power for them to collectively resolve common challenges they encountered. This system of government, also known as the marble cake federalism was seen around 1930 to 1960, when there was great depression and Second World War. During these periods, the united states needed the two levels of government to work collectively.
