Keisha is writing an essay about living in Hawaii. She includes the following:

Both residents and tourists frequent Hawaii Volcanoes National Park, which is home to two active volcanoes. Mauna Loa, one of the volcanoes found in the park, is taller than Mount Everest. In addition to its mammoth height, its width is even more impressive. Mauna Loa boasts a caldera that is approximately three miles in diameter and 600 feet deep. The caldera of a volcano is the impression or hole that is left after an eruption.
