What type of volcano is made up of only pyroclastic material that results from violent eruption?
A cinder cone volcano is made up of only pyroclastic material that results from a violent eruption. These eruptions typically eject a dense cloud of volcanic ash and other pyroclastic materials like rocks, and can have explosive and destructive outcomes.
If the magma of a volcano has a high amount of dissolved gas what type of eruption will the volcano have?
Typically, high viscosity, high gas magma results in a Plinian (explosive) eruption. The gas pulverizes the magma into ash and may form lateral pyroclastic flows.
What are the similarities in a lava flow and a pyroclastic flow?
A lava flow is simply a flow of liquid rock down a slope that usually results from an effusive eruption. A pyroclastic flow is an avalanche-like flow of hot ash, rock and gas that moves down a volcano during an explosive eruption, The move much faster than lava flows and are far more dangerous.
What kind of eruption is produced when basaltic lava that is low in silica flows from a volcano?
A basaltic lava eruption that is low in silica tends to produce effusive eruptions. These eruptions are characterized by relatively gentle and steady flows of lava, rather than explosive eruptions with ash and pyroclastic material. Basaltic lava flows easily due to its low viscosity, allowing it to travel long distances before cooling.
How is a baking soda volcanoes eruption similar to a real volcano eruption?
Both baking soda volcanoes and real volcanoes erupt by releasing gas and molten material from beneath the Earth's surface. The eruption results in the expulsion of materials (baking soda and vinegar for the baking soda volcano, and lava and ash for a real volcano) which flow outwards. Both types of eruptions can create a visual spectacle with plumes of gas and debris.

What is a hemorrhagic eruption?
A hemorrhagic eruption is a sudden outpouring of blood, or a rash that results in a sudden outpouring of blood.

Which volcao results in a violent eruption?
its the composite cone volcano?
What kind of eruption does mount pelee have?
Mount Pelee is known for its explosive eruptions due to the high viscosity of its lava, which traps gas until pressure builds up and causes explosive eruptions. This type of eruption can result in a devastating pyroclastic flow that travels down the volcano at high speeds, as was seen during the 1902 eruption of Mount Pelee.
What are factors affecting the shape of volcanic cone?
The shape of a volcanic cone is influenced by several factors, including the viscosity of the magma, the type of volcanic eruption, and the composition of the erupting materials. Viscous magma tends to produce steeper, more conical shapes, as it accumulates around the vent, leading to stratovolcanoes. In contrast, low-viscosity magma results in broader, gently sloping shield volcanoes due to the fluid lava spreading over larger areas. Additionally, the presence of pyroclastic materials and the frequency of eruptions can also affect the cone's overall morphology.
What is an eruption called when the magma is thin runny and contains very little silica?
An eruption with thin, runny magma containing very little silica is called an effusive eruption. This type of eruption usually results in lava flows that can travel long distances from the volcano.
What ia the difference between lava and pyroclastic material?
Lava is simply molten rock on the surface of the earth that flows as a viscous liquid. Pyroclastic material consists of rock fragments, molten, and partially molten material that is blasted out by explosive volcanic activity and eatiher rains down or flows downward as a density current.
What type of eruption does rhyolitic magma produce?
Rhyolitic magma typically produces explosive volcanic eruptions due to its high viscosity and gas content. This type of magma can trap gases, leading to increased pressure that results in violent eruptions when released. These eruptions often produce pyroclastic flows, ash clouds, and lava domes, making them among the most hazardous volcanic events. Examples of such eruptions can be seen at locations like Yellowstone and Mount St. Helens.
