Which set of magma conditions produces the most explosive eruptions?
Magma is a hot fluid from deep within the Earth's crust. The set of magma conditions that produce the most explosive eruptions are high viscosity and the presence of dissolved gases.
What type of magma that tends to cause explosive eruptions has a what?
High temperature
What type of eruption does MtFuji produce?
It is a composite volcano, so the kind of eruptions it has is explosive.
Why are eruptions deep in the ocean calmer than eruptions on land?
Eruptions in the deep ocean differ from eruptions on land for several reasons. The deep ocean eruptions are often tmes and depending on cause as well as location from basaltic magma. This type of magma is not known for its explosivity. The magma is the type that build the hawaiian volcanoes and more or less when erupting flows (Although it is capable of explosive eruptions). The other major factor is for an explosive eruption to be generated the magma must be very viscous to allow the build up of gas bubbles. The second half and what actually causes the explosive eruption is the explosive release of this gas. When an eruption occurs in the deep ocean it is not explosive due to the fact that the gas cannot decompress from the magma explosively due to the extreme pressures exerted by the water at such depth. Even if it were the right type of volcano that could generate explosive eruptions with the pressure it would be unable to do such a thing.
A volcano with a magma supply which is felsic and has a high viscosity will tend to have what type of eruption?
A volcano fed by felsic magma will tend to have explosive eruptions.

What kind of magma produce violent volcanoes eruptions?
Rhyolitic magma. This type of magma is found where the gases can't escape like in volcanic eruptions. Because the gas can not escape, the magma becomes viscous, resulting in the explosions being violent and unpredictable. The other type of magma is Basaltic magma. This can be found where continent plates are pulling away from each other and the magma is nearer the surface. This allows the gas to escape and therefore the magma is less viscous and doesn't result in explosive volcanoes, here eruptions are gentle and 'rifts' are more likely, where lava is persistent. I hope this helps! :)
What are the different type of eruptions?
Non-explosive and Explosive
What type of eruptions do mafic magmas cause?
Basaltic magmas are associated with fissure eruptions creating lava flows spilling out from cracks in the crust. This is because basaltic magmas are more viscous and contain a lower concentration of gases than rhyolitic magma and therefore are unable to build up sufficient pressure to produce explosive eruptions.
What type of eruptions cause a cinder cone?
Explosive
