In an explosive eruption, the summit may be blasted away. In large eruptions, so much magma may be erupted that a volcano can collapse into the space left behind, leaving a caldera.

Pyroclasic materials from shield volcanoes?
Pyroclastic flows don't come from shield volcanoes. They come from cinder cone and sometimes composite volcanoes. Shield volcanoes only erupt runny lava.
Is there water around a volcano?
Sometimes. Many volcanoes form islands, but not all do.
Why do the different types of volcanoes have different shapes to them?
Because sometimes they have explosions and change shape.
Do seismologists also study volcanoes?
They do occasionally, and they sometimes help vulcanologists. This is because volcanoes generate earthquakes, and analyzing patterns in these earthquakes can help to tell if a volcano is likely to erupt soon.
How do volcanoes cause acid rain?
Volcanoes cause acid rain because the gas bubbles built up in the molten rock are released and go into the air which can sometimes cause acid rain, the sulfur dioxide and nitrous oxides are burnt and these react with the water in the atmosphere, sulfuric and nitric acids are produced and the rain will have a lower pH level making it acidic to make acidic rain.
Why do volcanoes exisits?
volcanoes are mounds of earth that sometimes spurt molten rock out
Do volcanoes cause earth quakes?
Sometimes they do.
What are sometimes called smoking chimneys?
volcanoes
Do earthquakes and volcanoes alwyas occur at the same time?
sometimes yes, sometimes no.
What are the volcanoes on the sun?
There is no volcanoes on the sun, but sometimes a large energy release known as a solar flare can be mistaken for a volcano.
Pyroclasic materials from shield volcanoes?
Pyroclastic flows don't come from shield volcanoes. They come from cinder cone and sometimes composite volcanoes. Shield volcanoes only erupt runny lava.
What forms when continental plates push together?
Volcanoes or sometimes earthquake!
Do volcanoes erupt in places where two of the earths plates meet?
yes sometimes
Are crystals sometimes made by volcanoes.?
they aren't made BY volcanos but they are made in the volcanos
Is there water around a volcano?
Sometimes. Many volcanoes form islands, but not all do.
What kinds of lava do volcanoes with lower viscosity magma produce?
They produce basaltic lava.
Can radioactive waste be dumped into volcanoes?
This sounds a very bad idea, volcanoes erupt sometimes and would spew it out again. Even volcanoes that have not erupted for many years may do within the lifetime of the nuclear activity of the waste
