composite volcano
What are composite volcanoes also known as?
Composite volcanoes are also known as stratovolcanoes
Why are shield volcanoes named as such?
Shield volcanoes are named because they resemble a warrior's shield lying on the ground due to their broad, gently sloping profile.
Describe the appearance of cinder cone volcanoes.
Cinder cone volcanoes are small, steep-sided cones made up of pyroclastic fragments, such as volcanic ash and cinders.
Describe the typical shape of a composite volcano.
Composite volcanoes have a steep profile with a conical shape
What type of magma is commonly associated with shield volcanoes?
Shield volcanoes typically erupt with basaltic magma, which is low in silica content
How do cinder cone volcanoes typically form?
Cinder cone volcanoes form from the accumulation of ejected volcanic materials around a vent during moderately explosive eruptions.
What type of magma do composite volcanoes usually erupt?
Composite volcanoes typically erupt with viscous magma, which is high in silica content.
How do the eruption styles of shield volcanoes differ from composite volcanoes?
Eruptions from shield volcanoes are usually non-explosive and effusive, resulting in lava flows rather than explosive eruptions.
Are cinder cone eruptions usually explosive or non-explosive?
Cinder cone eruptions are typically moderately explosive.
What are some hazards associated with composite volcanoes?
Composite volcanoes can produce explosive eruptions, leading to ashfall, pyroclastic flows, and lahars.
