No. Pillow lava is basaltic, low-viscosity lava. Krakatoa is a stratovolcano with a style of ereuption more characteristic of high-viscosity andesitic lava.
Mount St. Helens is a stratovolcano, also known as a composite volcano. Stratovolcanoes are characterized by their steep, symmetrical cones built up by layers of hardened lava, ash, and rocks. They are known for explosive eruptions due to the high viscosity of their lava.
Stratovolcano (a composite volcano)
No. A stratovolcano is a volcano with steep slopes consiting of layers of lava flows, ash, and pumice and is prone to explosive eruptions. A shield volcano is a volcano with broad slopes composed of layers of low viscosity lava flows and is generally not prone to explosive eruptions.
Mount Pelee is a stratovolcano, which is characterized by its steep-sided cone shape made up of layers of hardened volcanic ash, lava, and other volcanic materials. Stratovolcanoes are known for their explosive eruptions due to the high viscosity of the magma.
Ulawun volcano is a stratovolcano, also known as a composite volcano. These volcanoes are known for their steep-sided conical shape and are composed of layers of hardened lava, volcanic ash, and pumice. Stratovolcanoes are typically associated with explosive eruptions due to the viscosity of their magma.
Nevado del Ruiz is a stratovolcano, not a shield volcano. Shield volcanoes are typically broad and have gentle slopes created by low-viscosity lava flows, while stratovolcanoes have steep slopes and are composed of alternating layers of hardened lava, tephra, and volcanic ash.
It is a stratovolcano, so it has a conical shape
Eyjafjallajökull is a stratovolcano, also known as a composite volcano, characterized by its steep slopes and explosive eruptions due to the high viscosity of its magma. It is located in Iceland and famously erupted in 2010, causing widespread disruption to air travel in Europe.
The viscosity significantly depend on the temperature. So it will be a decreasing curve rather than point. You have to look into the temperature--viscosity curve so that you can find the point you are interested in
Viscosity is a substances resistance to flow. So as the viscosity of a substance increases, the flow rate will decrease.
Yes. Mount Cameroon is a stratovolcano.
