What kind of igneous rocks for on earths surface?
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
What kind of igneous rock forms outside of a volcano?
A couple of them are obsidian and pumice.THEY ARE CALLED EXTRUSIVE IGNEOUS ROCKS...........THEY ARE SO CALLED BECAUSE THEY ARE FORMED FROM THE LAVATHAT HAS BEEN COOLED........
What kind of rock forms from the lava of an erupting volcano?
Igneous rock forms from the lava of an erupting volcano. This rock is created when molten rock cools and solidifies, either on the surface (extrusive igneous rock) or beneath the Earth's surface (intrusive igneous rock). Examples of igneous rocks include basalt, rhyolite, and granite.
Magma that cools slowly forms what kind of rock?
Intrusive igneous rocks are formed by slow cooling magma below the earth's surface. Extrusive igneous rock is formed by magma cooling quickly, at or near the surface.
What kind of rock is formed when lava cools fast?
Extrusive igneous rock is formed from rapidly cooling lava.
What kind of rock includes intrusive and extrusive kind of rocks?
Igneous.

What does extrusive rock means?
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
What kind of igneous rock usually contain large crystals?
Intrusive or granite.
What kind of igneous rock texture results from slow cooling magma?
A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture. The slower the magma cools the more time minerals have to crystallize and thus grow bigger.
What type of rocks form from lava after a volcanic eruption?
Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).

Has two kind intrusive and extrusive?
Foliated rock

Intrusive igneous rocks are formed by slow cooling magma below the earth's surface. Extrusive igneous rock is formed by magma cooling quickly, at or near the surface.
What kind of rock is formed when lava cools fast?

When melted rock cools or hardens on or under earths surface it forms what kind of rock?
It forms an igneous rock. If it is within the Earth, then it is an intrusive igneous rock (e.g. granite) and if it is erupted onto Earth's surface then it is an extrusive igneous rock (e.g. basalt).
