Rangitoto Island
The type of volcano is the shield volcano. Shield volcanoes can be found in Hawai'i.
A shield volcano is low and wide.
Basaltic, like Hawaii
Rangitoto Island
Basalt magma is low in viscosity, which allows it to flow more easily and spread out over a large area. As the magma rises to the surface and erupts, it creates layers of lava that build up and spread outwards, forming a broad shield shape characteristic of shield volcanoes like Rangitoto Island. The gentle slopes of the shield volcano are a result of the basaltic lava flowing long distances before solidifying.
