a)
The type of volcano and the features used in classification by observing the given photo.
a)
Answer to Problem 1GST
The volcano identified in the accompanying photo is composite or strato volcano and is identified by its shape.
Explanation of Solution
Volcanoes are massive conical structures that act as vents for the magma to flow on to the surface. The volcanoes mostly occur near the plate boundaries or sometimes occur along the stationary hot spots.
The given type of volcano is a composite or strato volcano. The feature used in identifying is its distinct shape even though the size is also consistent with a composite volcano. It has a symmetrical structure with steep summit area and gently sloping flanks.
b)
The eruptive style, the composition and viscosity of magma of the given volcano.
b)
Answer to Problem 1GST
This volcano has rhyolitic or andesitic composition with highly viscous magma and has explosive eruptive style.
Explanation of Solution
This type of volcano is characterized by explosive eruptions with pyroclastic flows, ash and lahars due to their thick and highly viscous magmas associated with them. They typically contain rhyolitic or andesitic composition.
c)
The type of plate boundary setting in the given volcano.
c)
Answer to Problem 1GST
They are mainly found at the convergent plate boundaries.
Explanation of Solution
Composite volcanoes are formed at the subduction zones where the Earth’s plates collide and the denser plate slides beneath the other. Hence, they are found at the convergent plate boundaries.
d)
The city that is vulnerable to the effects of the given volcano type.
d)
Answer to Problem 1GST
The cities which are located mostly near the convergent plate boundaries, such as Tokyo, Japan; Seattle, Washington; Mexico City, Mexico; and Naples, Italy are vulnerable to this type of volcano.
Explanation of Solution
The volcano given in the question is a composite type of volcano. Composite volcanoes consist of symmetrical structure with steep summit area and gently sloping flanks produced by andesitic magma with pyroclastic materials and lava flows. These are mostly seen at the convergent plate boundaries.
