Final answer:
The incorrect statement about Haleakala is an option(c) Another name for it is Mauna Kahalawai, as this is not the correct name for Haleakala. The volcano is located on Maui and it is in a post-shield stage of volcanic activity.
Step-by-step explanation:
The question 'All of the following are true about Haleakala, except:' presents four statements about Haleakala, a volcano in Hawaii, and asks which one is incorrect. After evaluating the statements given, it is clear that statement c) Another name for it is Mauna Kahalawai is the incorrect option.
Haleakalā is the name of a different volcano, located on the island of Maui and is indeed known to be an active volcano in a post-shield stage, as mentioned in statement d).
It's important to distinguish between the different volcanoes in the Hawaiian Islands. For example, Mount Kilauea and Mauna Loa are distinct active volcanoes found on the island of Hawaii.
They represent some of the most active volcanic areas on Earth due to the hot spot located underneath the island, which has been producing volcanic activity for at least 100 million years. This activity has created a long chain of volcanic islands, forming the Hawaiian archipelago.
Mauna Kea, another volcano on the island, is currently dormant and is celebrated as an exceptional location for astronomical observation due to its high altitude and clear skies.
