Why are Hawaiian volcanoes shield volcanoes?
Hawaiian volcanoes are shield volcanoes because they are characterized by their broad, gently sloping shape resembling a warrior's shield. This is due to the low viscosity of the basaltic lava they erupt, allowing it to flow easily and travel long distances before solidifying. As a result, shield volcanoes tend to build up gradually over time with successive eruptions, creating their distinctive shape.
What is the difference between Hawaiian volcanoes and those of the Ring of Fire?
The Pacific Ring of Fire literally surrounds the basin of the Pacific Ocean, whereas the Hawaiian volcanoes are the result of the Hawaiian hotspot.See the related Wikipedia links for pictures and more information:
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.
Rock formed in volcanoes?
Igneous rock is a result of cooled lava or magma.
The US received a number of islands as a result of the Spanish-American War Which of the following is not one of them?
The Hawaiian Islands.
What forms the islands of Hawaii?
The islands of Hawaii were formed from volcanic activity over millions of years. The islands are the result of magma rising from hot spots in the Earth's mantle, creating shield volcanoes that eventually emerged from the ocean. The movement of the Pacific tectonic plate over these hot spots has led to the formation of the Hawaiian island chain.
When are island arc volcanoes formed?
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
What are four states that are part of the ring of fire?
The four states that are part of the Ring of Fire are Alaska, Washington, Oregon, and California. The Ring of Fire is, in general, where the Pacific Plate is subducting underneath some other plate. The result is a line of volcanoes along the subduction boundary. Hawaii, which was mentioned as an answer, is not part of the Ring of Fire because its volcanoes were formed by a hot spot.
What type of volcano is formed at a weak spot in the middle of a plate?
A hotspot volcano is formed at a weak spot in the middle of a plate. This type of volcano is not located near tectonic plate boundaries and is usually the result of a plume of hot mantle material rising towards the surface, creating a volcanic hotspot. Examples of hotspot volcanoes include the Hawaiian Islands and Yellowstone National Park.
What were the Hawaiian formed as a result of?
The Hawaiian Islands were formed as a result of volcanic activity, specifically a hotspot that has been active for millions of years. As the Pacific tectonic plate moved over the hotspot, it created a chain of volcanic islands. The most active volcano in Hawaii, Kilauea, continues to add new land to the Big Island today.
What mountains did not form as a result of collision between two continents?
Some mountains, like volcanoes or hotspot mountains, form due to volcanic activity, not from the collision of continents. Examples include the Hawaiian Islands, formed by the movement of the Pacific Plate over a hot spot in the Earth's mantle, and Mount Kilimanjaro in Africa, which is a volcanic mountain formed independently of continental collisions.
Can volcanoes form because of an earthquake?
Not really. Earthquakes can and do occur when a volcano is forming, but the volcano is not a result of an earthquake. Volcanoes are formed when magma (molten rock) within the earth's crust reaches the surface.
