Final answer:
The tallest active volcano in the world is Ojos del Salado on the Chile-Argentina border, which stands at approximately 22,615 feet. While Hawaii's volcanoes, like Mauna Loa and Kilauea, are significant and active, they do not reach the height of Ojos del Salado. Regions like the Aleutian Islands and Antarctica also have active volcanoes, showcasing Earth's dynamic geology.
Step-by-step explanation:
The tallest active volcano in the world is not Mount Kilauea, although it is one of the most active. Instead, the title of the tallest active volcano belongs to Ojos del Salado on the Chile-Argentina border, which reaches approximately 22,615 feet (6,893 meters) in altitude. While Mount Kilauea, Mauna Loa, and Mauna Kea are significant volcanoes located in Hawaii, with Mauna Kea being the tallest mountain in Hawaii when measured from the base on the ocean floor, they do not surpass Ojos del Salado in height.
Hawaii is known for its volcanic activity, which is driven by a mantle hot spot that has created a chain of volcanic islands. This hot spot has been active for at least 100 million years, carving out a 3,500-kilometer-long chain of volcanic islands, including the world's largest individual mountains rising 9 kilometers above the ocean floor.
Mount Erebus is another significant active volcano, located in Antarctica, and it's the southernmost active volcano. It has a notable and continuous lava lake. Moreover, volcanic activity is not confined to the Hawaiian Islands; other regions such as the Aleutian Islands also demonstrate the dynamic nature of Earth's crust with active volcanoes like Cleveland Volcano.
