Final answer:
Article V of the Constitution sets out the amendment process, requiring a proposed amendment to be backed by a two-thirds majority in both houses of Congress or by two-thirds of the state legislatures, followed by ratification from three-fourths of the state legislatures or conventions in the states.
Step-by-step explanation:
The amendment process for the Constitution is outlined in Article V, which establishes a method for modifying the nation's paramount legal document. For an amendment to be adopted, it needs to go through two key stages. Initially, an amendment must be proposed either by a two-thirds majority vote in both the House of Representatives and the Senate, or by a convention called for by two-thirds of the state legislatures. Following the proposal, the amendment must then be ratified by three-fourths of the state legislatures or by conventions in three-fourths of the states. This rigorous process ensures that amendments are carefully considered and have widespread support before becoming part of the Constitution.
