Parts of a Volcano
Magma that flows out onto Earth's surface.
What is lava?
These are the three kinds of landforms are created by the eruptions of volcanoes?
What are Cindercone, Shield, and Composite?
This is molten rock beneath the earth's surface.
What is Magma?
This occurs when a crack in the earth's surface allow magma and gases to come to the surface.
What is a volcano?
Volcanoes that erupt constantly.
What are active volcanoes?
This is a combination of volcanic gasses that are released into the air.
What is a vog?
This type of volcanic landform is made up of small rock particles, or cinders. It is characterized by a small cone with steep sides.
What is a cinder cone volcano?
This is a mixture of cinder, ash, and rock that is emitted by a volcano.
What is tephra?
These are pieces of ash and lava that are blown into the air by a volcano.
What are cinders?
These volcanoes have become inactive, but people are not certain that they will not erupt again.
What are dormant volcanoes?
Openings through which volcanic materials erupt that are located near the surface of the mountain.
what is a vent?
This type of volcano is made up of layers of lava rocks. it's not as steep as cinder cone volcano and is created slowly that's why it has gentle and broad sides.
What is a shield volcano?
This is a body of water that is heated by an underground magma pool.
What is a hot spring?
These are three types of thermal eruptions.
What are hot springs, geysers, and mud pots.
These are the three ways to classify a volcano.
What are by shape, frequency of eruption, and type of eruption.
These are bowl-shaped depressions.
What are craters?
This type of volcanic landform is made up of layers of lava flows alternating with layers of ash, cinders, and rocks. it is a combination of cinder cone and shield volcanoes.
What is a composite volcano?
This is a hot spring that periodically blows steam and hot water into the air.
What is a geyser?
This prevents magma from gradually and slowly rising to the peak of the mountain?
What is rocks above magma press down on the magma and create great pressure. When the pressure is released, volcanic materials suddenly erupt and move out to the surface.
These are three different products of volcanoes.
What are enriched soil, gemstones, or igneous rock(types of igneous rock: pumice, obsidian, or granite)
This occurs when two plates collide. the denser; heavier, plate slides under the other plate and becomes part of the mantle.
What is the Subduction Zone.
This type of volcanic landform is the most destructive?This volcanic landform located in Washington was developed this way.
What is Composite volcano. What is Mt. St. Helens .
This is an avalanche of red hot dust and gases that are emitted by a volcano.
what is a pyroclastic flow?
This is how hot spots form new land.
What is hot spots erupt and release magma. As magma comes out it becomes lava and hardens into landforms?
Example: The Hawaiian islands are created by hot spots.
This is why volcanoes can have more than one type of eruption.
What is a volcanic eruption can change the structure of a volcano causing it to erupt differently in the future. (Example if a Cinder cone became a composite cone it would have a different eruption.)
