Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
Moderate to violent eruptions throwing volcanic ash cinders and lava high in to the air?
Cinder Cone Volcano
What type of magma that tends to cause explosive eruptions has a what?
High temperature
Can volcanic eruptions send ash 30km in the air?
Yes. Eruption columns nearly 45 km high have been recorded.
During a hurricanes water usually causes more destruction than high winds do?
High winds do cause more damage
Does low silica magma cause explosive volcanic eruptions?
Not usually. Explosive eruptions are more often to magma with high or moderate silica levels.
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.
What type of magma causes violent erpuptions?
Highly viscous felsic magma causes the most violent volcanic eruptions.
Is diorite a volcanic rock?
Yes. Diorite is a high-silica volcanic rock often associated with highly explosive eruptions.
Moderate to violent eruptions throwing volcanic ash cinders and lava high in to the air?
Cinder Cone Volcano
Do other planets have volcano eruptions?
There is some evidence of volcanic activity on Venus, but no conclusive evidence of any recent eruptions. In addition, Io, a moon of Jupiter has an extremely high rate of volcanic activity. Titan, a moon of Saturn, is believed to have volcanoes as well.
What type of magma that tends to cause explosive eruptions has a what?
High temperature
How can people prepare them selves for volcanic eruptions?
the lava goes on low ground so you have to go on high ground like Tacoma

Yes. Eruption columns nearly 45 km high have been recorded.
Do Hurricane water usually causes more destruction than high winds do?
High winds do cause more damage
How might volcanic activity affect changes in the climate?
Large volcanic eruptions blast millions of tons of dust and grit into the stratosphere, where the high-altitude winds carry it literally around the world. The dust reflects some tiny portion of the Sun's light back into space. This can cause substantially reduced temperatures, causing unseasonably cold summers and vicious winters for a year or two afterward. On April 5, 1815, Mount Tambora in Indonesia began a cataclysmic series of eruptions. The year of 1816 was sometimes called "The Year Without a Summer", causing crop failures worldwide,
