Want this question answered?
Rocks are mixtures and so do not have chemical formulas. Igneous rocks vary in composition, so there is no way of giving a formula.
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
Magma forms coarse crystalline intrusive igneous rocks such as granite or gabbro, depending on the chemical composition of the magma.
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
The mineral composition of the magma and the rate at which it cools determines what rock forms.
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.
The chemical composition of the rock affects the color of an igneous rockbecause some minerals like quartz change color becasue of t's own
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.
it can mean two things, (1)mineralogical composition or (2)Chemical composition

The percentage of its composition of silica.
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.
Rate of cooling of the magma and Chemical composition of the magma.

The color will depend on the mineral composition of the magma.
The mantle is made of ultramafic igneous rock.
Magma forms coarse crystalline intrusive igneous rocks such as granite or gabbro, depending on the chemical composition of the magma.
