VOLCANO
What is the name of the tube-like structure in a volcano that allows magma to move from beneath the Earth's surface to the vent?
CONDUIT
The process by which molten rock and gases escape from beneath the Earth's surface.
VOLCANISM
A volcano is a vent in the Earth's crust through which molten rock, gases, and ash are released, whereas a mountain is created by tectonic movements without any magma activity.
TRUE
Give positive outcomes of a volcanic eruptions.
GEOTHERMAL ENERGY, FERTILE SOILS, TOURISM
What is the term for the region beneath the Earth's crust where magma is stored?
MAGMA CHAMBER
It is the nature’s way of releasing an excessive amount of pressure that has built up inside of Earth.
VOLCANIC ERUPTION
In the spreading center volcanism, two separating oceanic plates create an oceanic rift or a mid-ocean ridge from which magma rising from Earth’s mantle escapes.
TRUE
Give negative outcomes of a volcanic eruptions.
DEVASTATED LAND, LOSS OF LIFE, LOW AIR QUALITY
Where are the majority of volcanoes located?
PACIFIC RING OF FIRE
Which stage of a volcano is marked by an extended period of inactivity, yet retains the possibility of erupting again in the future?
Subduction zone volcanism primarily associated with mantle plumes.
FALSE
Give the three types of volcanism.
SPREADING CENTER VOLCANISM
SUBDUCTION ZONE VOLCANISM
INTRAPLATE OR HOTSPOT VOLCANISM
The opening in the volcano where lava comes out.
VENT
Volcanoes can occur between tectonic plates due to?
INTRAPLATE OR HOTSPOT VOLCANISM
A volcano results from the release of pressure between tectonic plates, while an earthquake is caused by the release of pressure from within the Earth.
FALSE
Why do Earth needs volcanoes?
