Lava is, by preferred definition, a viscous fluid comprised of molten rock that has reached the surface. In this case, lava is not an igneous rock. However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.
All volcanic rocks are igneous, but not all igneous rocks are volcanic. Volcanic rocks are igneous rocks that cool at or above the surface. Such rocks are extrusive. Some igneous rocks cool underground and are termed intrusive or plutonic.
No. Igneous rocks can be divided into two general categories: intrusive and extrusive. Intrusive rocks form from magma that cools underground. Extrusive rocks are volcanic; they form from material that cools after being erupted.
Those would be igneous rocks. Extrusive igneous rocks.
No. Volcanic rock is extrusive igneous rock, which cools at or above earth's surface. However, igneous rocks can form from magama that cools inside the earth as well. This is called intrusive igneous rock, sometimes called plutonic rock.
Igneous rock is formed through the rock cycle. The igneous rock is formed by magma and lava,then it goes through volcanic activity.
Pumice is a volcanic "froth".
Sedimentary rocks can change to igneous rock when it goes through the rock cycle so a sediment can move to igneous rock where there is a volcanic activity happens making the the sediment get heat and pressure that makes igneous rock.So when you do the rock cycle you can go from igneous rock to a metamorphic rock.
Volcanic rock is igneous. This is because rock that forms fromt the cooling of molten material is the very definition of igneous rock.
It will be in a volcanic or sediment rock.

Volcanic rocks are considered igneous.
Volcanic activity produces extrusive igneous rock.
Those would be igneous rocks. Extrusive igneous rocks.
Volcanic rock is extrusive igneous rock.
