Does lava build up the land when a volcano erupts?
Yes Yes
How does a volcano interrupt?
A volcano erupts when gases build to an inescapable high pressure. The gas pushes magma and ash through the cone of the volcano causing an eruption.
Why does a mountain build around a volcano when a volcano erupts many times?
because the cynder, ashes and lava build around the volcano.and when the lava cools around it, it becomes a hard crust
How does a volcano AFFECT the environment?
When a volcano erupts, it then could build up more land, due to the lava drying up. Also it can damage the land, crops, vegetation, vice-versa. -TheBestAnswers.
How does volcanoes make island?
When a volcano erupts and the lava hardens it can build up under water and over time, if enough builds up, the result will be an island
What are the steps of the volcanic eruption?
1. Magma in the magma chamber begins to build up 2. Magma goes up into the pipe 3. The volcano erupts
How can you tell an vocano is about to erupt?
Before a Volcano "erupts" the mountain and surrounding areas will experience seismic activity (Earthquakes) for hours, days, weeks and even months before the initial eruption. Also Vulcanologist monitor gas emissions from the volcano to see if there is a build up gas. And of course there many be some steam/smoke coming from the volcano (Does not have to be from the cone of the volcano, can be from vents on the side or further down the volcano!) In the case of Mt St Helens - A "DOME" appeared on the side of the mountain, this was a build up of Magma further down the mountain slope in which grew larger by the day until the initial and catastrophic eruption.
Show the steps of erupting volcano?
steps to a volcano 1. an intense rumbling activates or awakens the volcano 2. eventually the volcano will start to shake or rumble 3. ash and molten rock will start to billow out 4. in an explosive eruption volcanic ash and molten rocks and magma/lava will fly into the air most likely destroying the volcano it self such as mt. st. Helens. In an non-explosive eruption lava will flow heavily down the side of the volcano with little to no ash. 5. anything in its destructive path will be destroyed! 6. people will die
Does lava erupt because of the heat?
NO, it erupts because of the build-up of pressure in the magma containment. When the pressure becomes so strong that there is no other way to release it, the lava rushes up and blows off the top of the volcano.
Why is it that the volcano which erupted last 600 years is more destructive or the probability of future eruption is higher?
If a volcano has not erupted in 600 years that probably means magma has been building up for all that time. If it erupts, it could eject all 600 years worth of material, which could amount to several cubic miles. Such and eruption would be very violent, producing enormous clouds of ash and pyroclastic flows. By contrast a volcano that erupts frequently has less of an opportunity tu build up a large volume of magma.
Do volcanoes do any good?
When a volcano erupts plants grow really quickly due to the ash produced by the volcano during the eruption, as it is good for the soil. Also the steep sides of a volcano once erupted are great habitats for rare animals or plants to stay protected.
How does a volcano build into a mountain?
A volcano forms a mountain as ash and/or lava build up over time from successive eruptions.
