Hawaiian Island Formation By:

The Hawaiian Islands How old are the Hawaiian Islands? Where were the Hawaiian Islands formed? How did the Hawaiian Islands form? What is a hotspot? What kind of rock are the Hawaiian Islands made from? What kind of volcanoes are on the Hawaiian Islands? What is the eruption history of the Hawaiian islands?

Where did it happen?

How did it happen? Volcanic Ridge is underwater. Volcanoes are pushed up above water, to form shield volcanoes.

Hot Spot Volcanoes can form in the center of the plate, like Hawaii in the Pacific plate, when magma rises until it comes out the sea floor, forming a fixed hot spot. The plate moved, while the hotspot did not, so the new Hawaiian islands were formed.

How did it happen p.2

What is the Hawaiian Islands made of? BASALT: volcanic, igneous rock that the Hawaiian islands are made of mostly.

Inside the volcano

eruption history Lava Flows from Mauna Loa volcano. Flows date ranges: 1780-1984ad Recorded by: Hawaiian Natives

Conclusion Facts: Volcanos formed on Pacific Plate. Fixed hotspot on moving plate. Made of Basalt.

Resources http://www.hawaii.edu/environment/ainakumuwai/html/ainakumuwaiisland formation.htm, a website on the Nawiliwili Bay under the Kaua’l Historical Society. Credibility Score: 7/10, .edu website that looks professional, but I’ve never heard about it before. http://volcano.oregonstate.edu/shield-volcanoes, a website that is run and edited by Oregon State University. Credibility Score: 6/10, seems credible, because it is from a college website. Doesn’t state author though.

Resources http://volcanoes.usgs.gov/images/pglossary/basalt.php, a geological survey website,in the US. Credibility score: 10/10, because it is a well-known credible website. https://www.soest.hawaii.edu/GG/HCV/mloa-eruptions.html, the Hawaii Center for Volcanology Credibility score: 9/10, states editor and information was updated a year ago, so fairly recent. http://loki.stockton.edu/~hozikm/geol/Courses/The%20Earth/Content%20Web% 20Pages/Mason/shield_volcanoes.htm, the University of New Jersey Credibility score: 6/10, public New Jersey University edited, but I don’t know the credibility of the website. States the author though, and seems pretty credible.

Thanks for listening!
