Branches of the Government

Chile is a Democratic Republic. There are three branches of power in Chile: 

Legislative Branch:

The Legislative Branch is the part of the government that writes up and votes on laws, also called legislation. It is represented by the Congress. There are two parts that make up the Congress: the House of Representatives and the Senate. 

Executive Branch: 

Its function is to administer the state. The leader of the Executive Branch is the President of the nation. The President holds all the power for this branch of the government and the other members report to the President. The President is chosen by the people. Presidential elections are held every four years. 

Judicial Branch: 

It is in charge of making sure people respect laws and judges whoever breaks it. The institution that represents the Judicial Branch is the Supreme Court. The Judicial Branch of the government is made up of judges and courts. The job of the courts is to interpret the laws of the Congress. Federal judges are not elected by the people. They are appointed by the president and then confirmed by the Senate.
