Nora was on a vacation in Hawaii and decided to study some rocks. What type of rock is Nora most likely to find while on an Island in Hawaii?

• She will find mainly igneous rock, because Hawaii has and was formed by active volcanoes.

• She will find mainly metamorphic rock, because Hawaii always has high temperatures.

• She will find mainly sedimentary rock, because Hawaii has a large amount of organic plant matter.

• She will find mainly sedimentary rock, because Hawaii has high winds and ocean currents.
