What is the viscosity of rangitoto volcano?
The viscosity of lava from Rangitoto volcano, which primarily consists of basalt, is relatively low compared to more silica-rich lavas. This low viscosity allows the lava to flow easily and form broad, gently sloping shield volcanoes. The typical viscosity of basaltic lava ranges from about 10 to 100 Pa·s, depending on temperature and gas content. As a result, Rangitoto's eruptions tend to be less explosive and more effusive, producing fluid lava flows.
The magma of shield volcanoes is rich in?
The magma of shield volcanoes is rich in basalt. Basalt magma is low in viscosity and gas content, allowing it to flow easily and lead to the broad, gently sloping shape characteristic of shield volcanoes.
What type of volcano is characterized by low silica magma and relatively nonviolent eruptions?
flood basalt, lava dome, and shield volcanoes do.
What is A type of volcano with broad and gentle slopes and built by the eruption of fluid basalt lave?
The type of volcano is the shield volcano. Shield volcanoes can be found in Hawai'i.
What kind of rock is found in a shield volcano?
Shield volcanoes are primarily composed of basaltic rock, which is a type of volcanic rock that is low in silica content and high in iron and magnesium. This type of rock creates gently sloping shield volcanoes due to its low viscosity and ability to flow easily during eruptions.
What type of volcano is Rangitoto Island?
It is a shield volcano.
What type of volcano is rangitoto?
It is a shield volcano
Why is rangitoto a shield volcano?
because it has a dome shape

Where is the closest volcano to Auckland?
The closest volcano to Auckland is Rangitoto Island, located about 8 kilometers (5 miles) to the northeast of the city. Rangitoto is a dormant shield volcano that last erupted approximately 600 years ago. It's a popular destination for hiking and offers panoramic views of Auckland and the surrounding Hauraki Gulf. The island is easily accessible by ferry from downtown Auckland.
How old is Mt Ruapehu?
Assuming you mean Rangitoto Island in the Hauraki region (there is another one in the Marlborough Sounds) . This last erupted as a pair of eruptions about 550 and 600 years ago. Human footprints have been found preserved in the ash deposits on the adjacent Motutapu Island. Rangitoto is a classic shield volcano, with a widespread, shallow angle, lava flow. Though there are some scoria cones.
The magma of shield volcanoes is rich in?
The magma of shield volcanoes is rich in basalt. Basalt magma is low in viscosity and gas content, allowing it to flow easily and lead to the broad, gently sloping shape characteristic of shield volcanoes.
Is basalt mountain a volcano in basalt Colorado?
Yes, Basalt Mountain is an ancient shield volcano and is no longer active. The cliffs facing town are evidence of a post-tertiary age collapse of the dome and expose the many layered flows indicative of shield volcanos.
Very broad volcano with gentle slopes formed from basalt lava?
