Felsic and Mafic are two very broad classifications for igneous rocks. This is based on their composition. Felsic rocks are rich in silicon and aluminum (e.g. granite) while Mafic rocks have higher concentrations of magnesium and iron (e.g. basalt).

What is an ignous rock?
Igneous is one of the three major rock classifications in geology. An igneous rock is a rock formed from the cooling and solidification of magma or lava.
What are two main classifications of igneous rocks?
The two types of igneous rock are are intrusive and extrusive, depending on where they form. Intrusive igneous rock forms underground from slow cooling magma. Extrusive igneous rock forms at or near the surface from quick cooling lava.

What are the 3 classifications of a rock?
The three classifications of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling and solidification of magma or lava. Sedimentary rocks are formed by the accumulation and lithification of sediments. Metamorphic rocks are formed from pre-existing rocks that undergo changes in response to heat, pressure, or chemically active fluids.
What are 3 classifications for rocks?
metamorphic, sedimentary and igneous
What are the 2 ways igneous rock are is formed?
Igneous rocks are formed through volcanic activity, where molten rock (magma) cools and solidifies either on the Earth's surface (extrusive igneous rock) or beneath the surface (intrusive igneous rock). These cooling processes result in the formation of crystals within the rock, determining its texture and composition.
How do magma turn into extrusive igneous rock?
Lava can turn into igneous rock in 2 ways. When the lava cools to a hardening point inside the volcano it is called intrusive igneous rock. When lava cools outside of the volcano it is called extrusive igneous rock.
What describes rock that was formed when molten rock cooled down?
Igneous rock is formed.
What are two types igneous rocks?
Granite and basalt are the most common types of igneous rock. Igneous rock types, or classifications, also include those that are intrusive and extrusive. Intrusive igneous rock is formed from the solidification of slow cooling magma below the surface. Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.
