I am not a Geologist, but I do know this: Rocks are composed of different minerals. In a field of gold, a rock could be made up of gold; likewise, in a field of silver, a rock could be made up of silver. The same is true of rocks that are made up of copper, zinc, feldspar, chalk, granite, marble, etc. Generally, when we look out the wiindow and see large rocks across the landscape, we call them "rocks". Closer observation would reveal their composition, should we need to know that.
Rocks are mixtures and so do not have chemical formulas. Igneous rocks vary in composition, so there is no way of giving a formula.
When magma crystallizes, igneous rocks are formed. The type of igneous rock that is formed depends on the chemical composition of the magma and the rate at which it cools.
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.
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
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.
Rocks are mixtures and so do not have chemical formulas. Igneous rocks vary in composition, so there is no way of giving a formula.
it can mean two things, (1)mineralogical composition or (2)Chemical composition
Rate of cooling of the magma and Chemical composition of the magma.
The mineral composition (silica content) is the chemical property most commonly used to classify igneous rocks. This can help differentiate between different types of igneous rocks, such as basalt, andesite, and granite.
When magma crystallizes, igneous rocks are formed. The type of igneous rock that is formed depends on the chemical composition of the magma and the rate at which it cools.
Yes, when lava cools and solidifies, it forms igneous rock. The type of rock that forms depends on the chemical composition of the lava and the rate at which it cools.
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.
It affects the color.
Their origin, and chemical composition.
