How are balances of power reflected in political boundaries and government power structures?

The balance of power is the system by which the public entities of the government, and even the nations among themselves, control their power so that no one obtains excessive prerogatives over the others. Thus, political limits are established for the exercise of power by the different bodies, such as the system of checks and balances through which Congress, for example, must authorize certain acts of the President so that they acquire full validity.
