Extract of sample "Earth and Space Science"

A gold nugget is a mineral because of the characteristics it possesses. One is a naturally occurring substance found in gold ore and has a specific gravity of around 15.5-19.3. Gold nugget has a specific color, which is yellow (Marshall, 50). Quartz is a mineral because it is naturally occurring in sedimentary rocks. Quartz has different colors but is mostly ranges from clear to it translucent color. Its luster is vitreous. Amber be classified as minerals because they are a combination of tree resin and other naturally occurring things such as plant and animal materials. It has a color range from yellow to orange and a specific gravity of 1.1.

Glacial ice forms due to a lot of icefalls and slow melting during the summer hence it solidifies to a glacier. So, a glacier can be categorized as a mineral formed by only one mineral and because of its defined formula and structure (Marshall, 60), Ruby is a mineral that is naturally occurring and is mined. Obsidian is a volcanic glass where it is pushed up as an extrusive igneous rock, so cannot be described as a mineral. Cubic zirconia is a mineral. It is synthetic and was discovered in monoclinic minerals.
