Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
Which of these substances is usually not present in explosive volcanic eruptions?
Pahoehoe is one substance usually not present in explosive volcanic eruptions. Tephra, lava and other gasses are typically present during an eruption.
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
What are the stages of an eruption column?
An eruption column consists of hot volcanic ash emitted during an explosive volcanic eruption. An explosive eruption always begins with some form of blockage in the crater of a volcano When magma flows towards the surface pressure builds, eventually causing the blockage to be blasted out in an explosive eruption. The pressure from the magma and gases are released through the weakest point in the cone, usually the crater. The sudden release of pressure causes the gases in the magma to suddenly froth and create volcanic ash and pumice, which is then ejected through the volcanic vent to create the signature eruption column commonly associated with explosive eruptions.
Where does pyroclastic flow occur?
Pyroclastic flows occur during explosive eruptions of volcanoes.
What usually explosive discharge of steam and volcanic material?
It is usally ash mixed with lava.
Did Hawaiian volcano have the most explosive eruption?
No. Volcanic eruptions in Hawaii are not usually explosive.
Which of these substances is usually not present in explosive volcanic eruptions?
Pahoehoe is one substance usually not present in explosive volcanic eruptions. Tephra, lava and other gasses are typically present during an eruption.
What is the underwater mountain of volcanic material?
Magma is the underwater mountain of volcanic material. The underwater mountain of volcanic material is usually in molten rock.
What is underwater mountain of volcanic material?
Magma is the underwater mountain of volcanic material. The underwater mountain of volcanic material is usually in molten rock.
What is a volcanic discharge?
A volcano erupts because there is mass pressure under it. In a volcano there is hot, melted rock called lava. The hot lava produces gasses that build up underground until there is too much for the rock to contain, that makes the eruption. When there is too much, it bursts the volcano. There are two types of eruptions. Non explosive and explosive. When they are explosive, it is caused by clouds of hot debris and gases.
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
Where is tuff rock found?
Tuff is usually found in and near areas that have experienced explosive volcanic eruptions.
What substances is usually not present in explosive volcanic eruptions?
Pastry is not usually present in explosive volcanic eruptions also you seldom find lettuce leaves or sharks.This answer is absolutely true and you may find it surprising. However, when you ask a question in the negative "not present" then almost everything you can think of would provide a true answer.
Is there a pahoehoe in a volcanic explosive eruption?
Not usually. Pahoehoe refers specifically to a lava flows. These can occur in mildly explosive eruptions, but usually explosive eruptions to not produce lava flows. Instreat they produce clouds of ash with some lapilli and pumice. Pryoclastic flows often result. These are fast-moving avalanches of superheated ash, gas and pumice. These form a kind of volcanic rock called tuff.
What kind of of volcanic eruption occurs when basaltic magma is present?
Basaltic magma usually produces a Hawaiian or Stombolian style of eruption.
