WHAT IS The largest volume of volcanic material is extruded through fractures in the crust?
The largest volume of volcanic material extruded through fractures in the crust is typically associated with fissure eruptions, which occur along linear volcanic fissures rather than from a single vent. These eruptions can produce extensive lava flows, including basalt, resulting in the formation of large volcanic plateaus, such as the Columbia River Basalt Group in the United States. Fissure eruptions often release vast amounts of gas and can lead to significant landscape changes over time.
Are cinders the most dangerous pyroclastic materials extruded from a volcano?
No. The most dangerous pyroclastic material is volcanic ash.
When silica-rich magma is extruded ash hot gases and larger fragments may be propelled from the vent at high speeds and produce which of the the following?
When silica-rich magma is extruded, it can create explosive eruptions like Plinian eruptions, where hot gases, ash, and larger volcanic fragments are propelled high into the air at high speeds. This can lead to the formation of pyroclastic flows, ash clouds, and volcanic bombs.
How did mt redoubt form?
Mount Redoubt is a stratovolcano located in Alaska's Aleutian Range. It formed through a series of volcanic eruptions and the accumulation of lava, ash, and other volcanic materials over time. The mountain's distinctive shape is the result of these eruptions and the subsequent cooling and solidification of volcanic materials.
Are volcanic eruptions rare?
Volcanic eruptions are common in some of the Earth's volcanic hot-spots.

How volcanic eruptions differ from earthquakes?
volcanic eruptions are hotter
Are volcanic eruptions rare?
Volcanic eruptions are common in some of the Earth's volcanic hot-spots.
How are magmatic materials transported to the surface?
Magmatic materials are transported to the surface through volcanic eruptions. When pressure builds up in the magma chamber below the surface, it can force the magma to erupt through a vent or fissure, releasing gases and molten rock onto the Earth's surface. This process can result in different types of volcanic eruptions, such as explosive eruptions or effusive eruptions.
Magma extruded at low temperatures tends to be what?
Magma extruded at low temperatures tends to be more viscous and can lead to the formation of features such as thick lava flows, domes, and explosive volcanic eruptions. This increased viscosity is often due to higher silica content, which can trap gases and result in more explosive activity. Consequently, the resulting volcanic rock is typically rhyolitic or dacitic in composition.
Which of these is not a form of volcanic material?
Basalt is not a form of volcanic material; it is a type of rock that is formed from solidified lava. Volcanic materials typically include lava, ash, and tephra, which are all products of volcanic eruptions.
Is igneous released in volcanic eruptions?
Correct. Igneous rocks fly out of volcanic eruptions
Is there any volcanic eruptions in Mars?
yes! volcanic eruptions happen on mars NASA
What are the kinds of volcanic eruptions?
The kinds of eruptions are the quiet eruptions and the explosive eruptions.
What type of material is produced by explosive eruptions?
Explosive eruptions typically produce pyroclastic material, which includes volcanic ash, lapilli (small rocks), and volcanic bombs (larger, rounded projectiles). These materials are ejected with great force during explosive eruptions, causing widespread damage and forming deposits around the volcanic vent.
