What type of volcanoes make up the Hawaiian islands and why is it easy to determine?
Shield volcanoes make up the Hawaiian islands. These volcanoes have low, broad profiles and are typically formed by the eruption of low-viscosity basaltic lava. It is easy to determine the type of volcanoes because of their distinctive shape and the lava flows they produce.
The Hawaiian islands has what type of plate boundary?
The Hawaiian Islands are located over a hotspot, where a tectonic plate moves over a stationary mantle plume. This is not a plate boundary, but rather a volcanic hotspot chain that has formed the Hawaiian Islands as the Pacific Plate moves slowly over it.
How where the hawaiian islands formed?
The Hawaiian Islands are volcanic in origin. Each island is made up of at least one primary volcano, although many islands are composites of more than one. The Big Island, for instance, is constructed of 5 major volcanoes: Kilauea, Mauna Loa, Mauna Kea, Hualalai and Kohala. Mauna Loa is the largest active volcano on Earth. Kilauea is presently one of the most productive volcanoes on Earth (in terms of how much lava it erupts each year). The primary volcanoes on each of the islands are known as a shield volcanoes, which are gently sloping mountains produced from a large number of generally very fluid lava flows. Hawaiian volcanoes primarily erupt a type of rock known as basalt. When molten, basalt produces liquids of relatively high fluidity, compared to volcanoes that erupt more silica rich magma types such as andesite, dacite or rhyolite. The fluidity of molten basalt favors the formation of lava flows, which is why the Hawaiian volcanoes generally have gentle sloping sides. By contrast, lavas with higher silica content are more viscous and commonly produce either thicker, shorter lava flows, thick blocky deposits and/or thick beds of ash that fall from the sky following explosive eruptions. These other types of volcanoes (common outside of Hawaii) are typically steeper sided. The Hawaiian volcanoes were produced by the Hawaiian hot spot, which is presently under the Big Island of Hawaii. The image below shows the islands of the Hawaiian chain and the intervening shallows, banks and reefs along a line from southeast to northwest. Note that the islands of Lanai and Kahoolawe are not shown because they would "overlap" with Molokai and Maui, respectively (see the map of the Islands on the Hawaiian Volcanoes page) In general, when you move along the island chain from southeast (Hawaii) to northwest, (Kure), the volcanoes become older and older.
Volcanic islands in the deep ocean are composed primarily of what igneous rock type?
Volcanic islands in the deep ocean are primarily composed of basaltic igneous rocks. Basalt is formed from the rapid cooling of lava erupted from underwater volcanoes, resulting in a fine-grained, dark-colored rock. It is the most common rock type found on volcanic islands like Hawaii and Iceland.
Many of the Caribbean islands were formed by what type of tectonic activity?
Many of the Caribbean islands were formed by volcanic activity along tectonic plate boundaries, particularly where the North American Plate and the Caribbean Plate interact. This activity has led to the creation of volcanic islands and underwater mountain chains in the region.
Which type of volcanoes formed the hawaiian islands?
Shield Volcano
How were the Hawaiian islands formed and which type of rock is probably most common in Hawaii?
they were formed by underwater volcanoes
What type of volcanoes are on the Hawaiian Islands?
Shield volcanoes
What type of a volcanoes are in the Hawaiian Islands?
They are shield volcanoes
What type of volcanoes make up the Hawaiian islands and why is it easy to determine?
Shield volcanoes make up the Hawaiian islands. These volcanoes have low, broad profiles and are typically formed by the eruption of low-viscosity basaltic lava. It is easy to determine the type of volcanoes because of their distinctive shape and the lava flows they produce.
What type of volcanoes are the hawiian islands?
The Hawaiian islands are made of two types of volcanoes, shield volcanoes and cinder cone volcanoes. Shield volcanoes have broad bases with gentle slopes. Cinder cone volcanoes have steeper sides, are made from fragments of lava, and are usually located at the base of shield volcanoes.
The Indonesian islands have volcanoes with a reputation for violent eruptions The volcanoes in the Hawaiian Islands seldom erupt violently What is the most likely explanation for the difference betw?
the type of lava
Are hawaiian islands cinder cone volcanoes?
The Hawaiian volcanoes can form cinder cones, however the type of volcano they are classified as is shield volcano due to their broad sloping sides and the ability for their lava to flow.No. The Hawaiian islands are shield volcanoes.
Which type of volcano is an island volcano?
Stratovolcanoes, shield volcanoes, and complex volcanoes have all formed islands.
What type of mountain is not formed do to plate collision?
hot spot volcanoes such as the Hawaiian island chain.
What volcano in Hawaii is a shield volcano?
All of the active and inactive volcanoes that are part of the Hawaiian-Emperor Seamount chain are shield volcanoes. Shield volcanoes are the result of Hot Spot volcanism which is the type of volcanic force that created the Hawaiian islands.
Will the Hawaiian islands be destroyed by a volcano?
While Hawaii is prone to volcanic activity due to the presence of active volcanoes, it is unlikely that the entire Hawaiian islands will be destroyed by a volcano. The islands have formed over millions of years through volcanic activity and erosion processes, and while volcanic eruptions can cause localized destruction, it is not expected to completely destroy the islands.
