Fill in the blank.
1. lava with a higher content of has higher viscosity.
2. if a large explosion causes the magma chamber below a volcano to empty, the volcano can
collapse and form a
3. shield volcanoes can form when less
lava flows quickly away from a vent.
4. during an oceanic plate convergence, the plate will sink.
5. the west coast of the united state has features formed by _
6. during the
of two tectonic plates, magma wills the space between two tectonic plates.
7. the only volcanic activity that is not formed at tectonic plate boundaries is
and volcanoes are linked severe weather events.
respond to the following based on your reading.
9. briefly describe what causes a volcanic eruption to be explosive.

silica

caldera

viscous

denser

subduction

divergence

hot spots

earthquakes

Explosions from composite volcanoes occur as a result of gas buildup within them. Shield volcanoes also may erupt explosively if water accumulates inside their vents.

    The response to all these is earthquakes

9. An explosive eruption is a very violent type of volcanic eruption and can be caused when enough gas has dissolved under pressure in a viscous magma in a way that when the lava is expelled it froths into volcanic ash when pressure is low at its vent
