Premise: The Arikok National Park takes up approximately 18 percent of the island of Aruba and includes three primary geological formations: the Aruba lava formation, a quartz diorite formation, and a limestone formation that extends inward from the coast. These formations have directly influenced Aruba's human settlement, as well as its natural wonders.
Hypothesis: The island of Aruba is completely formed of a lava, quartz diorite and limestone formations.
