Final answer:
Constitutions are mostly changed through the process of amendment, which involves proposing and ratifying an amendment.
Step-by-step explanation:
In most cases, constitutions are changed through the process of amendment.
To amend the constitution, there are typically two steps involved:
- Proposing an Amendment: Two-thirds of both chambers of Congress or two-thirds of the states may call a convention to propose an amendment.
- Ratifying an Amendment: Three-fourths of the state legislatures must agree to adopt the amendment.
Amending constitutions is a difficult process and has only been done twenty-seven times in the history of the United States.
