What is the hot liquid inside a volcano?

What is the hot liquid inside a volcano?

When hot, liquid rock (magma) erupts from a volcano onto Earth’s surface it is called lava. If there is pressure inside the volcano, this red-hot, glowing liquid may spurt up into the air like a fountain.

Which is hot liquid rock that pours out of a volcano?

Lava
Lava is the hot liquid rock that pours from an erupting volcano. Under the earth’s crust is molten rock called magma, along with explosive gases. Under the right conditions, the gases send the magma up through volcanoes, which act as vents in the surface of the earth. When magma reaches the surface, it becomes lava.

What liquids come out of a volcano?

Lava is the liquid material that comes out of a volcano during an eruption.

What is hot liquid rock?

Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals.

What comes out of the lava?

What is Lava? When a volcano erupts, the molten rock (or magma) that comes out of the Earth is called lava. Because lava is so hot (more than 1,100 degrees C, over 2,000 degrees F), it remains molten and flows across the ground until it cools and hardens into rock.

What is the hot molten or liquid rock called?

Liquid rock is called magma when it is underground and lava when it is above ground. What is the hot molten or liquid rock called? it is called magma What is the liquid rock in a volcano called?

What kind of material is released from a volcano?

When magma is eject ed by a volcano or other vent, the material is called lava. Magma that has cooled into a solid is called igneous rock. Magma is extremely hot—between 700° and 1,300° Celsius (1,292° and 2,372° Fahrenheit).

What kind of rock is formed from a volcanic eruption?

Lava eruptions can be “fire fountains” of liquid rock or thick, slow-moving rivers of molten material. Lava cools to form volcanic rock as well as volcanic glass. Magma can also extrude into Earth’s atmosphere as part of a violent volcanic explosion. This magma solidifies in the air to form volcanic rock called tephra.

What is the liquid state of rock called?

“Hot liquid rock” exposed at or above the surface is called lava whereas if it is below the surface it is called magma. What is the liquid state of rock when heated to a high temperature?
