Answer 1

The shifting of the Rio Grande necessitated the formation of an international group to negotiate border changes.

Step-by-step explanation:

A physical boundary that has necessitated the formation of an international group to negotiate border changes is the Rio Grande boundary between the United States and Mexico.

The shifting of the Rio Grande has led to disputes over the border between the two countries. In 1963, the International Boundary and Water Commission was established to manage and resolve such issues.

For example, in the case of the Chamizal dispute, the boundary was adjusted due to the river's shifting course, and the commission played a crucial role in negotiating the new border.
