What phrase describes the process by which the Constitution can be amended?

The phrase that describes the process by which the Constitution can be amended is "the amendment process." This process is specifically outlined in Article V of the Constitution. It provides two methods for proposing amendments: either by a two-thirds majority vote in both houses of Congress or by a constitutional convention called for by two-thirds of state legislatures. Furthermore, to ratify an amendment, approval from three-fourths of the state legislatures or conventions in three-fourths of the states is required. This structure ensures that any changes to the Constitution reflect a broad consensus among both federal and state representatives, highlighting the importance of stability and careful consideration when modifying the foundational document of the United States. The other options, while they represent important concepts related to government operations and constitutional interpretation, do not pertain specifically to the process of amending the Constitution itself.
