Earth & Space Science
The learners are engaged with different types of plate motions and discover which motion resulted in the formation of the Hawaiian Islands.
After completing this tutorial, you will be able to complete the following:
The Hawaiian Islands formed over many millions of years as the Pacific Plate moved over a stationary hot spot. Magma would spurt out of this stationary hot spot and eventually form an island. Approximately every 1,000,000 years, the hot spot under Hawai'i becomes active and makes another island. This island then moves as the Pacific Plate moves. About 3 million years ago, O'ahu was over the hot spot. Today, Mauna Loa and Kilauea volcanoes on the island of Hawai'i are over the hot spot.
The islands to the southeast of O'ahu are younger than O'ahu. These islands are Moloka'i, Lana'i, Maui, and Hawai'i. The island of Hawai'i, also known as the Big Island, is the youngest island in the Hawaiian Island chain. It is still over the hot spot. Below the ocean, and to the southeast of the Big Island, is another volcano erupting over the hot spot. It is called Loihi. In about 6,000 years, if it continues to grow, it might form another island.
