What is a molten rock that comes from a volcano called?
Molten rock (magma) that spews from a volcano is called lava, When it cools, the lava forms igneous rocks.
What is hot molten rock that you can find in an underground chamber?
Magma is the hot molten rock found in underground chambers, which forms when rocks melt at high temperatures and pressures beneath the Earth's surface. When magma reaches the surface, it is called lava.
What does molten rock and gas leave the volcano through?
Molten rock and gas leave the volcano through an opening in the Earth's crust called a vent. The molten rock, known as magma when underground and lava when at the surface, flows out of the vent during an eruption. Gases such as water vapor, carbon dioxide, and sulfur dioxide are also released into the atmosphere during volcanic activity.
Is a volcano a igneous rock?
Not necessarily. Igneous rock can be divided into two broad categories: intrusive rock and extrusive rock. Intrusive rock forms when molten rock cools and solidifies underground, so no volcanic activity is necessary. Extrusive rock forms above ground from molten rock that erupts from a volcano.
What molten rocks pour out of a volcano what is the rock called?
Molten rock that pours out of a volcano is called lava. Lava is the liquid rock that flows from a volcano during an eruption.
How does volcano differ from magma chamber?
A volcano is a vent or hole in the ground where molten rock and associated gasses erupt. A magma chamber is a chamber underground, often under a volcano, where molten rock is stored.
What does a volcano erupt?
Magma, ash, and lava, a substance of hot molten rock coming from underground.
Did pumice form underground?
No. Pumice forms above ground as frothy molten rock erupts from a volcano.
What is a molten rock that comes from a volcano called?
Molten rock (magma) that spews from a volcano is called lava, When it cools, the lava forms igneous rocks.
Is a volcano the result of the cooling and hardening deep underground?
Generally, the volcano is not the result of cooling and hardening deep underground. It is the molten magma in the core of the earth that, when it rises and breaks through the earth's crust, results in volcanic action.
What is hot molten rock that you can find in an underground chamber?
Magma is the hot molten rock found in underground chambers, which forms when rocks melt at high temperatures and pressures beneath the Earth's surface. When magma reaches the surface, it is called lava.
What is molten material that a volcano vent?
The molten material that a volcano vents is called magma when it is still underground and lava when it reaches the surface. Magma is generated by the partial melting of rocks in the Earth's mantle, and its composition can vary depending on the type of volcano. When a volcano erupts, it releases lava, gases, and ash onto the Earth's surface.
How hot is the lava of an inactive volcano?
An inactive volcano does not have lava. Lava is molten rock on the surface. If there is lava, then the volcano is either actively producing lava or has done so recently, which by definition means the volcano is active. When molten rock is underground it is called magma. Magma may or may not be prsent in an inactive volcano, but temperature ranges from 1,200 to 2,400 degrees Fahrenheit.
What are the names and sizes of things that come out of a volcano?
molten rock, magma (which it's underground lava), ash, steam, and poisones gas.
What does molten rock and gas leave the volcano through?
Molten rock and gas leave the volcano through an opening in the Earth's crust called a vent. The molten rock, known as magma when underground and lava when at the surface, flows out of the vent during an eruption. Gases such as water vapor, carbon dioxide, and sulfur dioxide are also released into the atmosphere during volcanic activity.
Molten rock at the surface is?
When you have a volcano the molten rock is called Magma when it is inside the volcano but when it gets out of the volcano it changes name to Lava.
How would you use Molten in a sentence?
Molten rock is in a volcano
