A rock is composed of combinations of minerals, each mineral having its own chemical formula and crystalline structure. Minerals are composed of an element or combination of elements. Granite, for instance, is an intrusive igneous rock composed ofthe minerals quartz, feldspar, mica, hornblende, and other combinations or ratios of minerals.
A mineral is a naturally-occurring inorganic (there are some exceptions to this) crystalline solid (though Mercury is regarded as a mineral) with a specific chemical composition and a characteristic internal regular geometric arrangement of atoms, sometimes expressed as natural crystal faces.
A rock is an aggregate of one (such as quartzite) or more (such as granite) mineral particles formed through either crystallization of molten magma (igneous rocks), settling of particles (sedimentary rocks), or reheating and pressure applied to pre-existing rocks (metamorphic rocks), with no set chemical composition or atomic structure.

What rock is usually composed of several different mineral?
Rock gypsum
Is a strong parallel alignment of different mineral bands in a metamorphic rock?
Foliation
Is a pumice rock a rock or a mineral?
Pumice is an extrusive igneous rock, not a mineral.
Why isn't a mineral a rock?
A rock is made out of many different minerals. A mineral is a building block that makes up rocks. A rock is like a pizza, and the minerals that make up this 'rock pizza' are things like the crust, the sauce, the pepperoni, and the cheese. Cheese alone does not make pizza, much like one mineral will not make a rock.
Why are mineral bands in metamorphic rocks light and dark colored?
Mineral bands are light and dark colored because they are different types of rock. In the rock cycle different types of rock can stack on top of each other, this can be subducted into the earth near the Mantle where there is enough pressure the rocks can start to melt and change. Because different types of rock metamorphose into different rocks you can have many layers in a type of rock. These can be light or dark colors depending on the rock.
How can you tell if you have a rock or a mineral?
A rock is made of different minerals.
What rock is usually composed of several different mineral?
Rock gypsum
What is a narrow channel of slab of a mineral that is different from the surrounding rock?
sulfur rock
What is the Difference between a rock cleavage and a mineral cleavage?
The mineral cleavage is made up of many other particles to form a rock when the rock cleavage is just a rock.
Why isn't cement a mineral?
No. A rock is an assemblage of at least two different minerals. One mineral can't be two or more minerals.
What is the chemical make up or mineral content a rock is made of?
Each rock has a different composition.
Is a rock an igneous rock?
No. Igneous, sedimentary, and metamorphic rocks are three different categories of rock.
Is quartz a mineral or a rock mineral rock Submit?
mineral
is rock salt a rock or mineral?

Why is a boulder not a mineral?
A mineral is a naturally occuring chemical compound. A mineral is different from a rock/boulder which can be an aggregate of minerals, or non minerals and does not have a specific chemical composition as a mineral does
Is a strong parallel alignment of different mineral bands in a metamorphic rock?
Foliation
Different types of metamorphic are distinguished by the?
arrangement of mineral grains within the rock
