When melted rock erupts from a volcano and hardens what kind of rock does it form?
Extrusive igneous rock.
How does an igneous rock develop?
When lava erupts from a volcano and cools down, it hardens and becomes an igneous rock
How does the metamorphic rock change into a igneous rock?
metamorphic rock melts into magma and volcano erupts. lava hardens and cools
Igneous rock form on eath surface?
Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.
How does a volcano form into a mountain?
Over time the magma chamber found inside volcanos is cut off from the mantle by tectonic plate movement. Without constant exchange of hot magma from the mantel to replace the colder magma in the volcano, (convection), the magma inside the volcano hardens into igneous rock.
Where does lava go when it erupts?
When lava reaches the surface, it quickly hardens into rock. The resulting rock will have either a glassy texture (with no crystals) or have a fine-grained texture (with small crystals) because the minerals have little or no time to crystallize.
How can lava flow from a volcano and become part of the rock cycle and eventually become a flow of lava again?
The lava is melted rock called magma when it is underground, then it is exposed and is then called lava. The volcano erupts, and it hardens into igneous rock. If the igneous rock heats up again, it is lava once more!
What kind of rock is left after a volcano erupts?
igneacious
Is a volcano a constructive foce of nature?
The volcano takes magma from the mantle of the earth and ejects it onto the crust's surface. When the lava cools it hardens into a volcanic rock or glass.
How can rock form when a volcano erupts?
The rock forms over a cooling process.
What kind of rock will from when a volcano erupts?
Volcanoes produce extrusive igneous rock.
What happens to lava after it comes out of the volcano?
eventually it hardens into rock
