How many islands does the Hawaiian chain consist of?
The Hawaiian chain consists of 137 islands, but only 6 main islands are typically included in maps and tourist itineraries: Hawaii (also known as the Big Island), Maui, Oahu, Kauai, Molokai, and Lanai.
Is an area where material from deep within the mantle rises and then melts forming magma?
This is known as a hotspot. Examples include the hotspot responsible for the Hawaiian Ridge-Emperor Seamounts chain and the one responsible for the significant volcanism of Iceland.
How many islands incorporate the Hawaiian Islands?
The Hawaiian Islands include eight major islands: Hawaii, Maui, Oahu, Kauai, Molokai, Lanai, Niihau, and Kahoolawe. It also includes many smaller islets, atolls, and underwater seamounts.
How many islands are there in Hawaiian chain?
There are 6 main ones.
What kind of geologic formation is Loihi is it part of the Hawaiian chain?
It is an undersea volcanco. Yes its apart of the hawaiian chain
How can a chain of seamounts be used to tell which way the pacific plate is moving?
Seamounts are submarine volcanoes that form on the ocean floor. They are formed by hotspots (which are hypothesised to be the result of mantle plumes although there is some controversy over this theory in the geophysical community) which cause melting of the crust. These hotspots in the upper mantle are in fixed locations, so as the tectonic plate moves over the hotspot a chain of seamounts forms creating a line in the direction of the plate movement.
How many volcanoes have formed over Hawaii's hotspot?
The Hawaii plume is responsible for the creation of the Hawaiian - Emperor seamount chain, a chain of volcanoes over 5,800 kilometres (3,600 miles) long. Four of these volcanoes are active, two are dormant, and more than 123 are extinct, many having since been ground beneath the waves by erosion as seamounts and atolls.This gives a total of more than 129 volcanoes as the pacific plate slid over this hotshot.
What kind of geologic formation is Loihi Is it a part of the Hawaiian Chain?
Loihi is a seamount; specifically an underwater volcano. It is definitely part of the Hawaiian chain.
What lives in Seamounts?
Sharks tuna and chepalopods all live in seamounts
What is the formation of a Hawaiian island?
The Hawaiian Islands are formed from a chain of volcanoes, some still active.
Why do geologists think that seamounts are extinct volcanoes?
beacuse the seamounts were once formed as volcanoes
What is the area where magma from deep within the mantle melts through the crust?
This is known as a hotspot. Examples include the hotspot responsible for the Hawaiian Ridge-Emperor Seamounts chain and the one responsible for the significant volcanism of Iceland.
