Volcanoes

Shield volcanoes have low silica magma, which is more fluid and runny compared to magma with higher silica content. This low silica content contributes to the gentle, flowing eruptions characteristic of shield volcanoes.

Rhyolitic lava is extremely viscous. This means it can hold more gas under pressure. The magma travels upward slowly until the gas, which has been held in place, comes out of solution pretty much all at one, resulting in an explosion. The high viscosity also means that the magma can build over time only to be released suddenly. Basaltic lava, which does not resist flow as much, can be extruded more gradually.

Mount Fuji typically has non-explosive eruptions, which are characterized by the slow release of lava and volcanic gases. However, there is also some evidence of explosive eruptions occurring in the past, which have produced ash clouds and pyroclastic flows.

Tuff, which is composed of volcanic ash that has been compacted and cemented together, would be commonly found near a volcano. Ash flows, volcanic breccias, and lahars are other types of sedimentary rocks that may also be found in volcanic regions.

Kimberlite magma originates in the Earth's mantle and can transport diamonds to the surface during explosive volcanic eruptions. These eruptions are fast and violent, creating an environment where diamonds can retain their structure and resist degradation during their journey to the surface within the kimberlite magma.

It is possible for Mount Vesuvius, the volcano that buried Pompeii, to erupt again as it is an active volcano. However, there is currently no imminent threat of an eruption. Scientists monitor the volcano closely to detect any signs of increased activity that could indicate a potential eruption.

Mount Fuji is primarily made of volcanic rock, specifically basaltic lava flows and ash deposits resulting from previous volcanic eruptions. These volcanic rocks contribute to the mountain's iconic conical shape and rugged appearance.

bc of the lava the slowly it dries the more of the composite volcano gets bigger and the faster it dries will get it's layered interior

Shield volcanoes typically form on hot spots. These volcanoes have gentle slopes due to the low-viscosity basaltic lava they produce. Examples of shield volcanoes formed on hot spots include Mauna Loa in Hawaii and Galapagos Islands in Ecuador.

Pliny the Younger witnessed the eruption of Mount Vesuvius in 79 AD, which buried the cities of Pompeii and Herculaneum in ash and pumice. He famously wrote detailed letters describing the event, providing valuable insights into the eruption.

The reason in science demonstrations at schools, vinegar and baking soda are used is that when these two ingredients are mixed, carbon dioxide gas is produced very rapidly. This makes the vinegar and anything else mixed in with it froth up and expand. This causes the "eruption" of the volcano.

An alternative approach may be to use diet cola and the mint candy known as "Mentos" as demonstrated on the US Discovery channel program "Mythbusters".

The mentos are covered in lots of small dimples. When a mento is dropped into diet cola, these dimples act as points of nucleation for the dissolved carbon dioxide in the cola meaning that bubbles form at these points. This causes lots of gas to be released very rapidly (just as if you'd shaken up the bottle of cola and taken the lid off).

Apparently the mint flavoured mentos are required for this to work (as they are covered in the tiny dimples whereas other flavours have different coatings which do not have the dimples).

This may be a suitable method of creating your volcanic eruption demonstration.

The 1631 eruption of Mount Vesuvius lasted for a few days. Reports of time suggest from 2 or 3 days to 4 or 5 days, after which the volcano was only about one third its former altitude. Links can be found below.

Yes, Mt. Sakurajima in Japan is an active stratovolcano, not a cinder cone. Stratovolcanoes are characterized by their steep slopes and explosive eruptions due to the high viscosity of their magma, whereas cinder cones are smaller and simpler in structure.

Some major eruption dates for Mount Rainier include around 5750 BC, 250 BC, and between 1820 and 1854. However, the volcano has had multiple smaller eruptions and periods of volcanic activity throughout its history.

Hekla volcano in Iceland is a classic stratovolcano that formed through a combination of repeated eruptions over thousands of years. It is located along a divergent boundary where the North American and Eurasian tectonic plates are moving apart, allowing magma to rise to the surface and build up the volcano.ูล

Yes, in the positive value sense, volcanoes in the ocean help to create new landmasses such as islands.

In the negative value sense, on the continents they can move tons of earth, destroy or change the landscape, and kill most life forms in their path.

But life bounces back as it did when Mt. Saint Helens blew-up back in 1980 in the state of Washington.

The Ring of Fire, located around the Pacific Ocean basin, is home to the majority of Earth's active volcanoes. Countries such as Indonesia, Japan, the Philippines, and Chile have some of the most active volcanic regions in the world.

An example of a volcano that is currently inactive but has the potential to erupt again in the future is Mount Rainier in Washington, USA. It is considered a dormant stratovolcano with a history of explosive eruptions and is closely monitored for signs of potential activity.

it is estimated to be about 7000 degrees celsius

1000 degrees hotter than the outer core (6000 degrees celsius)

It is difficult to determine the exact volume of Krakatau volcano as it is an active volcanic island with changing topography due to eruptions and collapses. Its volume would vary depending on specific measurements taken at a given point in time.

The cryptodome on the side of Mount St. Helens was approximately 1,300 feet long, 65 feet wide, and 40 feet high. It was a large bulge caused by rising magma beneath the volcano before its 1980 eruption.

Evacuation is the main thing governments can do to reduce loss of life. But for the most part there is no effective way stop the eruption/volcanic activity from happening, as the forces are too large to be countered.

Damage can be reduced by avoiding the known paths of lava from preceding eruptions, or by locating towns on the far side of an intervening hill or deep water body. The latter does, however, present a tsunami risk and does not protect from ashfall or pyroclastic events.

it affects it because any earthquake or different types of events happens an it will affect plate tectonics because it is stronger then plate tectonics for example lava or magma when a volcanos errupts it could burn some plate tectonic when theres a sunami it could also affected especialy if theres a earthquake for example 5.8 or bigger since the streets brake into pieces it could affect it

Hualalai is located on the Big Island of Hawaii, so the people living near Hualalai include residents of the nearby towns of Kailua-Kona, Holualoa, and Waikoloa Village. Additionally, there are resorts and vacation rentals along the Kona coast where visitors stay.

It is not appropriate to label schools as "violent" without proper context or information. School violence can vary widely based on numerous factors and should be addressed through research and interventions rather than stigmatizing particular institutions.
