Why does the volcanic eruption happen ?
When the pressure on magma chamber inside earth increase and push magma to the surface.
When it formes by eruption lava and ash.
when rock underground suddenly breaks along a fault.
A volcano is a mountain that has an opening to allow hot vapor, and gas to escape from the pool of magma below.
True
False
Where is the Ring of Fire located?
Atlantic Plate
Pacific Plate
Japanese Plate
North American Plate
How does water get into the magma of Ring of Fire volcanoes?
There are springs and reservoirs under the volcanic magma.
The water gets into the magma from melting glaciers.
Seawater is carried with the subducting plate into the mantle.
The magma is basaltic and has no water in it.
What geologic hazards are caused by Ring of Fire volcanic eruptions? (Select all that apply)
Earthquakes
Volcanic Eruptions
Mudslides
Tsunamis
What geological features surround the Ring of Fire in the Pacific that aren't found in the Atlantic Ocean?
Mid-ocean ridges
Coral reefs
Subduction trenches
Hot spots
Why are Ring of Fire volcanic eruptions more violent than Hawaiian volcanoes?
The magma is more viscous due to increased silica and holds more gases.
The magma is less viscous due to silica and the gases escape easier.
The lava is more ropey and thin which is more explosive.
Methane in the lava causes it to be explosive.
What percentage of all earthquakes occur around the Ring of Fire?
25%
50%
75%
90%
