Parts of a Volcano
When it explodes we call it "lava," but inside the ground, it is called _________.
Magma
The outermost layer of the Earth is called the _________.
Crust
This type of volcano is a broad, gently sloping volcano characterized by its shield-like shape, resulting from eruptions of highly fluid, low-viscosity lava that spreads widely.
Shield volcano
How is the throat of a volcano similar to the throat of a human?
The throat of a volcano is what surrounds the main vent. Magma travels through it. The throat of a human is where food and air travel into the body.
Why is it called a "shield" volcano?
Magma flows travels the ____________ as it escapes the top of the volcano.
Main Vent
This type of boundary occurs where two tectonic plates move TOWARD one another and collide.
Convergent Plate Boundary
What is the name for a type of volcanic cone formed by the accumulation of cinders or scoria (small, broken pieces of solidified lava) that are ejected from a volcanic vent during explosive eruptions
Cinder cone volcano
Core
This type of plate boundary can cause earthquakes.
Transform plate boundary.
Lava comes out of the ____________.
Crater
This type of boundary occurs when two tectonic plates move PAST each other.
Transform plate boundary
This type of volcano is characterized by its steep, conical shape and formation through the layering of different volcanic materials like lava, ash, and pyroclastic flows.
Composite volcano or stratovolcano
Parícutin, a volcano in Mexico that erupted in 1943 and continued for nine years, is an example of what type of volcano?
Cinder cone volcano
This type of plate boundary creates fold mountains.
Convergent plate boundary
Magma is stored underground in the ____________.
Magma chamber
This type of boundary occurs when two tectonic plates move AWAY from each other.
Divergent plate boundary
WhAt is the name for a large, bowl-shaped volcanic depression formed when a volcano collapses inward, usually after a major eruption?
Caldera
Mauna Loa and Kīlauea in Hawaii are examples of what type of volcano?
Shield volcano
Mount Vesuvius in Italy is this type of volcano.
Stratovolcano or composite volcano
What is the name for rock fragments and particles ejected by a volcanic eruption?
Tephra
Mantle
What is the name for fragments of volcanic rock and ash ejected from a volcano during an explosive eruption
Pyroclastic material
Most volcanoes are found on the boundary of _____________.
Tectonic plates
This type of plate boundary forms a fissure volcano.
Divergent plate boundary
