The separation of powers, a political term popularized by Montesquieu but originated from Ancient Greece, is a system of designating each branch of government a specific role and checks and balances they can perform on other branches. This prevents one branch from gaining absolute power or abusing their power. This type of system was used by the American government when the founding fathers were first writing the constitution, this was all done to prevent the new government from becoming a Monarchy.
Ah! Welcome to the Systems of Checks and Balances 101! When the Constitution was being drafted the Founding Fathers knew that systems of government were susceptible to corruption and, in sense, could create another unfair system.
So the founding fathers ran with an idea called the System of Checks and Balances, which delegated powers to three branches to over rule the other branches.
The way majority of this works is between the Legislative and Executive branches (they tend to use the majority of the checks and balances system, however, the Judicial Branch as an extremely important and vital role too.)
When Congress (Senate and the House of Representatives) form a new law, they need to have the bill approved by the President for ratification (goes into law). Now the President has the choice to either ratify and sign the law into effect or veto and reject the bill back into Congress.
Now as you can see, the President could easily; If corrupted - turn over the government by constantly vetoing laws. However the Congress has a power to them that allows them to go over the Presidents Head. This is called the 2/3rd Majority rule.
If the veto'ed bill is sent back and both the houses of Congress vote to pass it by 2/3rd of the people in the house and in the senate, then the bill can become law without the president ever resigning it.
I bet you're wondering where the Supreme Court is in all of this, right? Well the Supreme Court has a vital function. Their job is to make sure your fundamental and constitutional rights are protected.
Example: Congress writes a new law saying "No one shall speak the word of their religion during any group assembly or in the newspaper." and the President of the United States signed it into law.
Now the Supreme Courts powers become active. They review the laws and denote their constitutionality and interpret the laws. Which as you can see in our example, that new law, would violate your 1st Amendment protections completely. The Supreme Court would now say "This law is unconstitutional and therefore is repealed immediately" and the law would be removed.
I've taken the liberty of including a flow chart below to show how the process works.
