What makes a valcano errupt?
If the rocks below the volcano melt, the liquid rock will gather in a chamber underground. As the pressure in this chamber increases the magma may be forced out. This is an eruption. Eruptions are more likely to be explosive if the magma contains a large amount of water or gas, as the expansion of the water or gas makes the magma explode as it is released.
What is volcanic acid?
Volcanic acid is acid that forms as a result of volcanic gasses reacting with water. The primary cause of this is sulfur dioxide, which reacts with water and oxygen to form sulfuric acid. Other contributors may include hydrogen fluoride, hydrogen chloride, and nitrogen oxides, which will form hydrofluoric, hydrochloric, and nitric acids respectively. Some volcanoes hold acidic lakes in their craters. The term may also refer to a proprietary oil/gas well stimulation treatment product provided by Halliburton.
Does a volcano has both quiet and explosive eruptions?
A volcanic eruption is more explosive if the magma or lava has a high viscosity, which means it is thick. A volcano like MT Kilauea in Hawaii has thinner magma which flows more freely from the volcano. If it's thicker more gas is created and it can also cause blockages which make for a larger explosion.
Does Mount St Helens lava flow violently or quietly?
Lava can't flow violently. Highly explosive eruptions such as the 1980 eruption of Mount St. Helens do not produce lava flows: they produce clouds of ash, gas, and pumice. Mount St. Helens has produced "quiet" lava flows at times.
What are the side effects associated with using senna?
Stomach cramps, diarrhea, gas, which can be severe if the herb is over used. Overdose: fainting, dehydration, electrolyte disorders leading to cardiac disorders. Take the lowest effective dosage and more . . .
Which gas is not produced by volcanic eruptions?
oxygen
Do all volcanic eruptions emit a large amount of gas?
I am currently in Earth Science and according to the "Pearson Earth Science" book, YES, all volcanic eruptions emit a large amount of gas. The quantity of emitted gas can exceed thousands of tons each day
What was the next form of pollution after volcanic eruptions and forest fires?
air pollution and molten gas
Is the one thing all volcanic eruptions have in common is that they emit large amounts of gas?
Yes
Why is silica rich magma associated with explosive eruptions?
silica rich magma associated with explosive eruptions because it tends to trap water and gas bubbles :)
Is ash the gas of lava?
No. Volcanic ash is not gas. It is made of tiny solid particles of rock or glass formed either when molten rock is fragmented or when solid rock is pulverized by explosive eruptions. Gas from a volcano is simply called volcanic gas.
Is magma a explosive eruption and why?
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.
Why do volcanic eruptions differ?
The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.
Is there anything that warns us that a volcano is going to erupt?
Yes. Volcanic eruptions are often preceded by earthquakes, venting of steam and gas, and very slight change to the shape of the volcano. Large eruptions are often preceded by smaller eruptions.
Where does the heat from inside the earth escapes through?
Mostly volcanic eruptions, and the release of heated gas in hotsprings, geysers, and underwater gasbeds.
Is ash the same thing as gas from a volcano?
No. Volcanic ash consists of tiny solid particles of rock and glass that get blasted out during explosive eruptions.
What is a pumice source?
Pumice is produced in the lava from certain volcanic eruptions. It forms from gas-rich andesitic or rhyolitic lava and has so many gas bubbles that some pumice can float on water.
