Quartz is a compound. There are many different types of quartz, each containing different materials.
Granite is a mixture. It is composed of various minerals such as quartz, feldspar, and mica that are physically combined but do not form a homogeneous solution.
Chalk is a heterogeneous substance because it is composed of various materials such as calcium carbonate, quartz, clay, and other minerals. These materials are not uniformly distributed throughout the chalk, resulting in a non-uniform composition.
Granite is a heterogeneous substance. This is due to the fact that it does not appear to be consistently made of one material. An example of a homogeneous substance would be water.
It's obvious from a cursory visual inspection that it's hetereogeneous. Anything with swirls, or specks, or any pattern other than a solid color is hetereogeneous (the reverse is not necessarily true; being a solid color does not always mean that it's homogeneous).
A granite countertop is a heterogeneous mixture. Granite, the main material in a granite countertop, is a type of metamorphic rock that contains minerals such as quartz and feldspar. Quartz and feldspar are two different types of minerals which make up granite. Therefore, because there are two different types of minerals in one substance it makes it heterogeneous.
Quartz is a homogeneous substance. It is the compound silicon dioxide, SiO2.

Granite is a heterogeneous mixture because it is made up of different minerals such as quartz, feldspar, and mica that are unevenly distributed throughout the rock.

Granite is a heterogeneous mixture. This means that it is made of different substances that remain physically separate.
It's obvious from a cursory visual inspection that it's hetereogeneous. Anything with swirls, or specks, or any pattern other than a solid color is hetereogeneous (the reverse is not necessarily true; being a solid color does not always mean that it's homogeneous).
A mixture of sand and water would be a heterogeneous mixture because the sand doesn't dissolve within the waterHeterogeneous.See the Related Questions to the left for more information.

Pure quartz is homogeneous. However, so-called quartz rocks found in nature are usually heterogeneous.
Ah, marble is a beautiful natural material that is actually a type of rock, my friend. It is considered a homogeneous mixture because it is made up of different minerals that are evenly distributed throughout. Just like how we blend colors on our palette to create a masterpiece, marble combines different elements to form its unique and lovely appearance.
