What else can I help you with?
If a volcano contained magma with small proportions of water and silica would you predict a nonexplosive eruption or an explosive one why?
This would result in a non-explosive, "runny" eruption, similar to what you get in Hawaii, where the volcano simply pours out lava. Explosive reactions occur when rocks contain large amounts of water and silica, which flash into steam, resulting in a rapid expansion, and thus a dangerously explosive reaction.
What type of volcano results from alternating explosives and nonexplosives eruptions?
A stratovolcano, also known as a composite volcano, results from alternating explosive and nonexplosive eruptions. These volcanoes are typically tall, steep-sided and are composed of layers of lava flows, ash, and volcanic rocks. Stratovolcanoes are known for their explosive eruptions due to the build up of pressure from the alternating eruptions.
What type of volcano is Tajumulco volcano?
Tajumulco volcano is a stratovolcano, also known as composite volcano. These are tall, steep-sided volcanoes built up by alternating layers of lava flows, ash, and volcanic rocks.
What type of eruptions does the Unzen volcano make?
The Unzen volcano in Japan has mainly produced explosive eruptions, characterized by the ejection of ash, rocks, and pyroclastic flows. These eruptions are caused by the build-up of pressure from magma beneath the surface.
What rock is formed when a volcano explodes?
An andesite rock. it came out of the volcanic eruption of Mt. St. Helens...

What is formed by explosive eruptions by a volcano?
Explosive eruptions will produce pyroclastic rocks such as scoria, pumice, and tuff.
Explain what makes a volcano explosive?
rocks and hot moving plates

What type of lava does an explosive eruption produce?
An explosive eruption typically produces thick and sticky lava known as silica-rich or felsic lava. This type of lava has high viscosity and trapped gas bubbles, causing it to erupt violently. As the lava is very viscous, it can block and build pressure in the volcano, resulting in explosive eruptions.
How would you calculate the age of a volcano?
Scientists usually find the age of volcanoes through radiometric dating of their rocks.
What type of volcano is whakaari?
Whakaari, also known as White Island, is a stratovolcano. It is a conical volcano composed of layers of ash, lava, and volcanic rocks. This type of volcano is known for its explosive eruptions and can be found at subduction zones.
What are the rocks found on Taal volcano?
Taal volcano is mainly composed of basaltic and andesitic rocks, as well as pyroclastic materials such as tephra, ash, and pumice. The rock types suggest a history of explosive eruptions mixed with effusive lava flows. Additionally, the presence of dacitic rocks indicates episodes of more evolved magma compositions.
