What else can I help you with?
What solar events occur during volcanic eruptions?
There are no Solar events that are connected to volcanic eruptions.
What plate boundary is not associated with volcanic eruptions?
Transform boundaries do not produce volcanic activity.
What volcanic activity caused the most destruction in Pompeii?
volcanic activity caused the most destruction in pompeii
Where have people stopped volcanic eruption?
There has never been an instance where a volcanic eruption has been prevented from occurring by human means.
Are volcanic islands caused by earthquakes?
It is more accurate to say that the process that creates volcanic islands also produces earthquakes.
A bowl shaped depression that forms around the vent of a volcano is a?
A bowl-shaped depression that forms around the vent of a volcano is a crater. These craters can be formed by the explosion of volcanic material or the collapse of the volcanic cone following an eruption.
What is a steep sided usually circular depression formed by either explosion or collapse at a volcanic vent called?
Volcanic crater.
How does a crater differ from a caldera?
A crater is at the top of the central vent in most volcanoes and is funnel-shaped, and is already made, a caldera is a magma chamber that supplied material to the volcano until it empties and the roof collapses.
What makes the volcanoes crater?
A volcanic crater is a circular depression caused by volcanic activity.
A basin shaped volcanic depression?
A caldera.
What volcanic events formed Crater Lake Oregon?
The large volcanic depression occupied by Crater Lake, Oregon is a
Where is Dallol?
Dallol is a volcanic explosion crater in the Danakil Depression in Ethiopia.
Define pyroclastic material and list three examples?
Pyroclastic material consists of fragments of rocks that forms during a volcanic eruption. Pyroclastic particles that are less than 2mm in diameter are called Volcanic Ash. Volcanic ash that are less than o.25 mm in diameter is called volcanic Dust. Large Pyroclastic particles that are less than 64 mm in diameter are called Lapilli
What is the the opening at the top of a volcano?
A volcanic vent. There may also be a crater (a concave depression or pit). This is known as a volcanic vent. It may sit at the base of a volcanic crater.
What are volcanic rock particles ranging in diameter from .25mm to less than 5mm?
Volcanic rock particles in this size range are classified as either lapilli or volcanic ash, depending on their exact size. Lapilli are volcanic rock fragments between 2 mm and 64 mm in diameter, while volcanic ash particles are smaller than 2 mm.
When the top of a volcanic mountain collapses it forms a what?
When the top of a volcanic mountain collapses, it forms a volcanic crater or caldera. This creates a bowl-shaped depression at the summit of the volcano.
What is the geothermal gradient in non-volcanic areas?
The average geothermal gradient in non-volcanic areas is typically around 25-30 degrees Celsius per kilometer of depth. This means that the temperature increases by this amount for every kilometer deeper into the Earth's crust.
