SCIENCE Flashcards
It is a vent, hill or mountain that erupts releasing molten rocks.
Volcano
Made by Pyroclastic fragments and Volcanic ashes
Cinder Cone
Also known as Stratosvolcanoes are typically symmetrical cones
Composite Volcanoes
It is the simplest volcano
Cinder Cone
Is formed from non - acidic basaltic lava
Sheild Volcano
It has erupted during historical times
Active Volcano
It is active but not erupting
Dormant Volcano
They have not had any eruption in the past 10,000 years
Extinct Volcanoes
What are the Phases of Volcanic eruptions?
Preparation Phase
Eruption Phase
Ending Phase
It involves the outpouring of balsaltic lava
Effusive Eruptions
Involves magma of high viscosity
Explosive Eruptions
Fluid Basaltic lava is thrown into the air
Hawaiian type
Identify what part of the Phases of Volcanic Eruption is it.
It is after the eruption, the magma chamber is now empty
Ending phase
Identify what part of the Phases of Volcanic Eruption is it.
The pressure will start to build up inside the magma chamber.
eruption phase
Identify what part of the Phases of Volcanic Eruption is it.
The magma chamber is being filled with magma.
preparation phase
Glowing Lava
Strombolian
The eruption is short, explosive and violent.
Vulcanian
The * most violent* eruption
Plinian
Steam driven explosion
phreatic
Reacts to external water
phreatomagmatic
GOOD EFFECTS OR BAD EFFECTS
OF VOLCANIC ERUPTIONS
The high levels of heat can provide an alternative source of energy
GOOD EFFECTS
GOOD EFFECTS OR BAD EFFECTS
OF VOLCANIC ERUPTIONS
Volcanic Ashes and gases ejected into the air may cause breathing problems when inhaled.
BAD EFFECTS
It is the energy derived from the center of earth
Geothermal Energy
