What type of magma is generally characterized as having low viscosity and is associated with non-violent or relatively quiet volcanic eruptions?
Basaltic magma is generally characterized as having low viscosity and is associated with non-violent or relatively quiet volcanic eruptions. Its low silica content allows it to flow easily, enabling lava to travel great distances. This type of magma is commonly found in shield volcanoes, where gentle eruptions lead to the formation of broad, gently sloping landforms. Examples include the eruptions of Hawaii's Mauna Loa and Kilauea volcanoes.
The type of volcano formed from violent eruptions of a volcano?
A stratovolcano, also known as a composite volcano, is formed from violent eruptions characterized by explosive activity that ejects a mixture of lava, ash, and volcanic rocks. These eruptions are typically associated with high levels of gas pressure within the magma chamber, leading to explosive events.
What type of eruption is it when it has silica?
Eruptions characterized by high silica content are typically explosive and are known as silicic or rhyolitic eruptions. The high viscosity of silica-rich magma traps gases, leading to increased pressure and violent eruptions. This type of eruption can produce pyroclastic flows, ash clouds, and volcanic domes, contrasting with the more effusive eruptions associated with low-silica basaltic magma.
The most explosive volcanic eruptions are associated with what type of volcano?
The most explosive volcanic eruptions are typically associated with stratovolcanoes, also known as composite volcanoes. These volcanoes have steep profiles and are characterized by a combination of explosive eruptions and lava flows, primarily due to their viscous magma, which can trap gas. The buildup of pressure from gas accumulation leads to violent eruptions, as seen in volcanoes like Mount St. Helens and Mount Vesuvius.
The type of magma that often produces a violent eruptions can be described?
Thick due to high silica content.
What word means mudflow?
The word for mudflow is "lahar." It is a type of volcanic mudflow composed of volcanic debris mixed with water. Lahars can be highly destructive and flow rapidly down the slopes of volcanoes during eruptions.
What is the difference between a lahar and a mudflow?
A lahar is a type of mudflow specifically composed of volcanic debris and water, often triggered by volcanic eruptions or volcanic activity. A mudflow, on the other hand, is a rapid flow of water-saturated earth materials that can occur due to heavy rainfall, snowmelt, or other natural causes.

Define violent eruption?
A violent eruption is a type of volcanic eruption characterized by explosive outbursts of magma, gases, and ash. This type of eruption often occurs when there is a high pressure buildup within the volcano, leading to the rapid release of energy. Violent eruptions can produce pyroclastic flows, ash clouds, and significant lava fountains, resulting in considerable destruction and hazards to nearby areas. Such eruptions are typically associated with stratovolcanoes and can have far-reaching impacts on the environment and human activities.
Rhyolite is associated with what type of eruption?
Rhyolite is associated with explosive eruptions.
The type of magma that often produces a violent eruptions can be described?
Thick due to high silica content.
What type of magma causes violent erpuptions?
Highly viscous felsic magma causes the most violent volcanic eruptions.
Why are some volcanic eruptions gentle and others violent and why do scientists make a distinction?
It's because of the silica content. Some with high silica are explosive and violent. The ones with lower silica are gentle, and leak out. (might have it backwards. need to brush up on my volcano facts)
What type of eruption does Colima produce?
Colima produces explosive eruptions, characterized by the sudden release of gas, ash, and magma. These eruptions can generate pyroclastic flows, lava flows, and volcanic ash plumes.
