The Principle of Popular Sovereignty posits that the power that the Government wields is granted to it by the will of the people.
This power is given to the Government through the election of representatives who then have to make sure that the interests of the people are taken care of. This shows that political authority rests with the people.
Ideally speaking, when the principle of Popular Sovereignty is followed, leaders are elected to serve the people and this they must do. In reality however, this is not always the case.
The low pressure helps us predict that there is going to be precipitation; however, since the temperature is above that of the freezing point of water, there will be no snow. Therefore, we can predict a rain shower.<span />
