Question 5

The major islands of the state of Hawaii are formed from a line of separate volcanoes emerging from the ocean floor of the Pacific Plate. The line extends from Kauai in the northwest, to Hawai'i in the southeast over a range of hundreds of miles. Kauai was formed from volcanoes that formed about 5 million years ago; on Hawai'i the volcanoes are currently active. ​ Explain the process that formed the Hawaiian Islands and what information a geophysicist could determine about the motion of Earth's parts from observing them.

Accepted Answer

In the deep layers of the mantle, a hot
