Which of these substances is usually not present in explosive volcanic eruptions?
Pahoehoe is one substance usually not present in explosive volcanic eruptions. Tephra, lava and other gasses are typically present during an eruption.
Which types of eruptions produce pahoehoe lava?
Pahoehoe lava is typically produced during effusive, non-explosive eruptions that have low viscosity and high temperatures. These types of eruptions are commonly associated with shield volcanoes, where the lava flows smoothly and forms a ropey or wrinkled surface as it cools.
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.
Can non explosive volcanoes have pyroclastic flows?
The answer is Explosive . It is explosive because during a explosive eruption there are clouds of ash, gas , and rock , and with a pyroclastic flow there is dust and ash . there for the answer must be explosive .
What are 3 examples of Pyroclastic debris?
Ash, pumice, and volcanic bombs are examples of pyroclastic debris produced during volcanic eruptions. These materials are fragments of volcanic rock that are ejected during explosive eruptions and can vary in size and composition.
Are pahoehoe and AA are produced during explosive eruptions?
Pahoehoe comes from an explosive eruption, whereas AA comes from quiet eruptions.

Why does ash cinders and bombs only produced during explosive eruptions from a volcano?
It requires an explosive force to hurl and fragment the molten rock like that. Non explosive eruptions extrude rock more "gently".

Is mount Fuji an explosive volcano or a non-explosive volcano?
Mount Fuji is considered a stratovolcano, which means it has the potential for both explosive and non-explosive eruptions. Historically, it has exhibited explosive behavior, particularly during its last major eruption in 1707. However, eruptions can vary in intensity, and some eruptions may be non-explosive, characterized by lava flows rather than explosive ash clouds. Overall, while it has the capability for explosive eruptions, it can also produce less violent activity.
What are 3 examples of Pyroclastic debris?
Ash, pumice, and volcanic bombs are examples of pyroclastic debris produced during volcanic eruptions. These materials are fragments of volcanic rock that are ejected during explosive eruptions and can vary in size and composition.
Does a pyroclastic flow typically occur during a quiet eruption?
No, pyroclastic flows typically occur during explosive volcanic eruptions when hot gas and volcanic particles travel rapidly down the side of the volcano. Quiet eruptions, such as lava flows, do not produce pyroclastic flows.
What is the difference of viscosity of magma in quiet eruptions and explosive eruptions?
During a quiet eruption lava flows from vents, setting fire to, and then burying, everything in its path. During an explosive eruption, a volcano can belch out hot clouds of deadly gases as well as ash, cinders, and bombs
How are Pillow Lava and Pahoehoe lava the same?
Both pillow lava and pahoehoe lava are types of basaltic lava that form during submarine volcanic eruptions. They both have smooth, ropy surfaces, caused by the flow of lava, and are relatively low in viscosity.
Is it true that pyroclastic flow typically occurs during a quiet eruption?
No. Pyroclastic flows are characteristic of explosive eruptions.
