Igneous rocks are rocks that have been formed from the cooling of flowing magma from a volcano or crack in the earth with lava beneath it. Igenous may or may not form crystals in there composition, and most of the rocks are from the mantle or the lower crust.
igneous rocks form within earths surface
No we do not have igneous rocks in Nigeria because there are no volcanoes in Nigeria and it is lava or magma that make igneous rocks.
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
Extrusive igneous rocks. The type of extrusive igneous rock is determined by the composition of the lava.
no

Rhyolititcen rocks.
Igneous rocks are formed by the solidification of molten materials.
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.

Yes. Volcanic rocks are extrusive igneous rocks.
No, igneous rocks are harder than sedimentary rocks on average.
Sort of. An igneous rock is one that started as molten magma and then cooled and solidified either above, on, or below the surface.
extrusive igneous rocks =/
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
