- Q1
If volcano's magma is high in silica, the volcano will probably
erupt quietly
erupt explosively
remain inactive
produce dark color lava
30s - Q2
Which is not a factor affecting volcanoes eruptive style?
amount of dissolved gases
age of magma
temperature of magma
chemical composition of magma
30s - Q3
Which statement is correct?
Magma with more silica content is relatively fluid and travels far before solidifying
The higher the temperature of magma is, the lower is its viscosity
All of the above
Magma with high silica content are less viscous than with low silica content

30s - Q8
What is the most explosive type of eruption?
Plinian
Vulcanian
Strombolian
Phreatomagmatic
30s - Q9
How do geothermal power stations work?
Cold water is heated up and water power turbines under the water and turns it into electricity
Cold water is pumped down and cold water meets the hot water from inside the Earth to produce steam to power turbines then creating electricity
The hot water from inside the earth meets cold air and produces condensation which powers the turbines and turns it into electricity
30s - Q10
Why are precautionary measures observed on volcanic eruptions?
A. To protect properties
B. To prevent the loss of lives
C.To pinpoint volcanic danger zone
D. Both A and B
