Explain the concept of manifest destiny and how that contributed to america's expansion?

by I tell you what -

Manifest Destiny was a 19th-century belief that the expansion of the US throughout the American continents was both justified and inevitable.

They got all hyped up on coca cola and jolly ranchers and began moving out west fast as all heck. Firstly many believed God himself approved of their decision to expend westward ( you know how fierce religious beliefs were). Then you have to remember the impact gold can have on a mans mind, they heard bout gold in California and well the reasons added up to make it seem nearly criminal not to go. Those are just some of my reasons of how the belief in manifest destiny compounded the influence upon much of the american people. ( pardon some non-factual events )

1) checks and balances- this idea is implemented in the constitution to ensure that no one branch of the federal government gains too much power. for example, the legislative branch(congress) can approve a bill that will then be sent to the executive branch (president). if the president does not like the bill or thinks that it violates the rights of citizens, he/she can veto the bill. vetoing the bill stops the bill from becoming a law. this check on power ensures that congress makes laws that do not violate the rights of citizens.

2) anti-federalists do not want to ratify the constitution unless it includes a bill of rights. the anti-federalists are worried that the constitution gives too much power to the federal government. having a strong central government caused problems when the us was still part of great britain. this is why the anti-federalists are fearful of this type of system.

3) federalists want a new constitution passed because it will fix america's weak political structure. before the us constitution is implemented, the constitution being used is known as the articles of confederation. this constitution has an extremely weak central government, allowing for disunity among the states.

can't do the whole thing, hope this
