Final answer:
The Guantanamo Bay naval base is the U.S. base located in the Caribbean and granted to the U.S. under the 1903 Cuban-American Treaty.
Step-by-step explanation:
The U.S. naval base in the Caribbean Sea that is on land granted to the U.S. under the 1903 Cuban-American Treaty is Guantanamo Bay. The United States ended up occupying these areas post the Spanish-American War in 1898, turning itself into a global power.
Guantanamo Bay in Cuba was ceded to the United States through the Platt Amendment, which allowed the United States to interfere in Cuban affairs and secured its right to have a naval and coaling station in Cuba.
After the war, Cuba technically became a free country and adopted a constitution based on the U.S. Constitution. While the Teller Amendment prohibited the United States from annexing Cuba
The subsequent Platt Amendment secured the right of the United States to interfere in Cuban affairs. This amendment also guaranteed the United States its own naval station on the southern Guantanamo Bay.
