The two types are extrusive igneous rock, which solidifies from magma on the surface, and intrusive igneous rock, which solidifies below the surface. Basalt is extrusive, granite is intrusive.
magma and hot molten lava
Rhyolititcen rocks.
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
Igneous rocks are formed by the solidification of molten materials.
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.
No, igneous rocks are harder than sedimentary rocks on average.
Since igneous rocks are divided into two categories (intrusive and extrusive) an igneous rocks can be intrusive.
No. Igneous, sedimentary, and metamorphic rocks are three different categories of rock.
Sedimentary, metamorphic and igneous.
Igneous, metamorphic and sedimentary are the three rock types.
igneous rocks
Neither, Igneous rock is either intrusive or extrusive. Thats what intrusive and extrusive is... A igneous rock.
Igneous--those that form directly from a molten state. Sedimentary--those that form from eroded particles of various sizes from other rocks. Metamorphic--igneous and sedimentary rocks, and sometimes metamorphic rocks, that undergo a transformation from heat and/or pressure.
