What is the name of the volcano feature that is left from hardened magma in the vent?
crater
The crater is the bowl shaped opening located at the top of the volcano. The crater is also the steep sided walls made of hardened lava that surround the main vent.
When magma hardens in a volcano’s pipe the result will eventually be a landform called a?
Ch. 15 Review Volcanoes
| Question | Answer |
|---|---|
| When magma hardens in a volcano’s pipe, the result will eventually be a landform called a | volcanic neck |
| Magma that forces across rock layer hardens into a | dike |
| In the United States, where do shield volcanoes occur? | Hawaiian Islands |
What is hardened magma in a volcano’s pipe?
Hardened magma in a volcano’s pipe remaining after softer rock around it has eroded away is a batholith. The opening through which magma flows through a volcano to the Earth’s surface is a caldera.
What forms when magma forces itself between rock layers and hardens?
Magma that forces itself across rock layers hardens into a dike. Magma that squeezes between horizontal rock layers hardens to form a sill. A batholith is a mass of rock formed when a large body of magma cools inside the crust.
What happens if a volcano’s magma is high in silica?
Lava with high silica content is thick and viscous and does not readily flow. Lava rises up toward the surface but is too thick to squeeze through the cracks and fissures in the Earth. As lava continues to rise upward, pressure continues to build.
What are the active volcanoes in the Philippines and its location?
Volcanoes of the Philippines
| Item No. | Name of Volcano | Province |
|---|---|---|
| 1 | Babuyan Claro | Babuyan Island Group, Cagayan in Luzon |
| 2 | Banahaw | Boundaries of Laguna and Quezon in Luzon |
| 3 | Biliran (Anas) | Leyte in Visayas |
| 4 | Bud Dajo | Sulu in Mindanao |
What’s a dead volcano called?
An extinct volcano is “dead” — it hasn’t erupted in the past 10,000 years and is not expected to ever erupt again. For example, if a volcano’s eruptive history shows that it usually erupts every 10,000 years or so, and there hasn’t been an eruption for a million years, it may be called extinct.
How does the magma form in a volcano?
These materials build up around the vent in a cone-shaped hill is called this hardened magma in a volcano’s pipe that remains when softer rock around it has worn away is called this. This forms when Magma forces itself across rock layers and hardens. A mass of rock that forms when a large body of magma cools inside the crust is called this.
What kind of hole is left after a volcano eruption?
The bowl-shaped area around a volcano’s central vent is called this. A pyroclastic flow typically occurs during this type of eruption. A huge hole, or ________ is left when the roof of a volcanic mountain’s magma chamber collapses.
How does a pyroclastic flow occur in a volcano?
A pyroclastic flow typically occurs during this type of eruption. A huge hole, or ________ is left when the roof of a volcanic mountain’s magma chamber collapses. Type of volcano with high silica magma, that is thick and sticky, and when the volcano erupts it produces ash, cinders, and bombs.
Which is an example of a quiet volcano eruption?
A string of islands, known a/n _____________ can form from the collision of two oceanic plates, Japan and New Zealand are examples of this. The main hazard from a quiet volcanic eruption is this. The bowl-shaped area around a volcano’s central vent is called this. A pyroclastic flow typically occurs during this type of eruption.
