The Three Branches of Government
How Power is Shared and Checked
The U.S. government divides its powers among three branches: legislative, executive, and judicial. Each branch has its own roles, but they also interact and check each other.
Legislative Branch (Congress)
Congress makes the laws. It consists of the House of Representatives and the Senate. Members are elected by the people and represent districts or states.
Executive Branch
The President leads the executive branch, enforcing laws, conducting diplomacy, and acting as Commander-in-Chief of the military.
Judicial Branch
The courts, topped by the Supreme Court, interpret laws and settle disputes.
Checks and Balances in Action
- The President can veto bills, but Congress can override vetoes.
- Courts can declare laws unconstitutional.
- The Senate confirms Supreme Court justices.
Why it Matters
This system keeps government fair, prevents tyranny, and encourages cooperation.
Everyday Example
If Congress passes a law, the President must sign it, and courts may later review it if it's challenged.
Examples
The Senate rejects a presidential appointment to the Supreme Court.
The Supreme Court strikes down a law as unconstitutional.
In a Nutshell
U.S. government power is divided among three branches that check and balance each other.
