Ultimate Mineral Trivia Facts Quiz!

The powder of a mineral is called its streak. Streak refers to the color of the powdered form of a mineral when it is scraped across a rough surface. It can be different from the color of the mineral itself. Streak is a useful property for identifying minerals as it often provides a more consistent and reliable color than the mineral's external appearance.

On the Moh's Hardness scale, talc is the softest mineral with a hardness of 1, while diamond is the hardest mineral with a hardness of 10. This scale is used to measure the relative hardness of minerals, with talc being easily scratched by other minerals and diamond being able to scratch all other minerals.

Coal is not a mineral because minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. While coal is derived from organic matter (plants) and is composed mainly of carbon, it does not meet the criteria to be classified as a mineral.

Inorganic refers to substances or materials that are not derived from living organisms. It includes minerals, metals, and non-metallic compounds that are not produced by biological processes. These substances are typically formed through geological or chemical processes and do not contain carbon or carbon-hydrogen bonds. Therefore, the correct answer is non-living things.

Cleavage is the tendency of a mineral to break along flat, smooth surfaces. This means that when a mineral is subjected to stress, it will break along specific planes of weakness, resulting in flat and smooth surfaces. This is different from fracture, which is the tendency of a mineral to break irregularly and not along specific planes. Luster refers to the appearance of a mineral's surface in terms of its shine or reflectivity, while hardness refers to a mineral's resistance to scratching.

Sulfates are a type of mineral that contain sulfides. This means that within this mineral group, all minerals will have sulfides present. Sulfates are compounds that contain the sulfate ion (SO4^2-) and are commonly found in minerals such as gypsum and barite. Therefore, the correct answer is sulfates.

The image is showing a test for a mineral's streak. Streak is the color of the powdered form of a mineral when it is scraped across a porcelain plate. This test helps in identifying minerals as different minerals have different streak colors.

Minerals that cool quickly will have weak bonds and small-sized crystal shapes. When minerals cool rapidly, the atoms within the mineral do not have enough time to arrange themselves into a highly ordered and tightly packed structure. As a result, the bonds between the atoms are weaker, leading to small-sized crystal shapes.

The specific gravity of a substance is the ratio of its density to the density of a reference substance, usually water. In this case, the weight of the mineral in air is greater than its weight in water, indicating that the mineral is denser than water. The specific gravity is calculated by dividing the weight in air by the difference between the weight in air and the weight in water. So, in this case, the specific gravity would be 55g / (55g - 44g) = 5.

The NC gemstone refers to the gemstone that is associated with the state of North Carolina. Emerald is the correct answer because North Carolina is known for its emerald deposits. The state is home to the Crabtree Emerald Mine, which is one of the most famous emerald mines in North America. Therefore, emerald is the gemstone that is commonly associated with North Carolina.

Feldspar is the most mined mineral in NC because it is widely used in the production of ceramics, glass, and porcelain. It is also used as a filler in various products such as paint, rubber, and plastics. The abundance of feldspar deposits in North Carolina makes it a lucrative mineral to mine, contributing significantly to the state's mining industry. Additionally, feldspar is known for its unique properties, including its resistance to heat and chemical reactions, making it highly desirable in various industrial applications.

Hardness refers to a mineral's resistance to abrasion, which means its ability to withstand scratching or being rubbed against a rough surface. The hardness of a mineral is determined by the strength of its atomic bonds. Minerals with a higher hardness are more durable and less likely to be scratched or damaged. Therefore, hardness is the correct answer for the given question.

Shaft mining involves digging a vertical or inclined passageway called a shaft down to the ore deposit. From the shaft, tunnels are then dug in various directions, including horizontally, vertically, or diagonally, to access the ore. This method is commonly used when the ore deposit is deep underground. The other options listed, such as strip mining, mountain top removal, and open-pit mining, do not involve the use of a shaft to access the ore.

The silicon-oxygen tetrahedron structure is made up of one silicon atom bonded to four oxygen atoms. This structure is commonly found in silicate minerals, which are the most abundant minerals on Earth's crust. The silicon atom is located at the center of the tetrahedron, with each of the four oxygen atoms bonded to it. This arrangement gives the tetrahedron a 3-dimensional shape, with the silicon atom at the center and the oxygen atoms surrounding it.

Mica has 1 plane of cleavage, which means it can be easily split into thin, flexible sheets along one direction. This property is due to the arrangement of its atoms and the weak bonds between them.

An ore refers to a large area that contains minerals that can be mined for profit. This suggests that the given answer is correct.

Diamond is a non-silicate mineral because it is composed primarily of carbon, while silicate minerals are composed of silicon and oxygen. Silicates are the most common type of minerals on Earth, but diamond is an exception to this as it is formed under high pressure and temperature conditions deep within the Earth's mantle. Diamond is known for its hardness and is used in various industries, such as jewelry and cutting tools.

Covalent bonds are the strongest type of mineral bonds. In a covalent bond, atoms share electrons, creating a strong bond between them. This type of bond is formed between nonmetal atoms, such as carbon and oxygen, and is characterized by its high bond energy and stability. Covalent bonds are responsible for the formation of many minerals, including diamond and quartz, which are known for their hardness and durability.

Gold, Silver, and Copper are examples of native elements. Native elements are minerals that occur naturally in an uncombined form, meaning they are composed of only one element. In this case, gold, silver, and copper exist as pure elements in nature and are not combined with any other elements. Therefore, the correct answer is native elements.

The correct answer includes three environmental results of surface mining: increase in erosion, ground and water contamination, and deforestation. Surface mining involves the removal of topsoil and vegetation, which can lead to increased erosion as there is no longer a protective layer to prevent soil from being washed away by rain or wind. Additionally, the process of mining can release pollutants into the air and water, contaminating both the ground and water sources. Lastly, surface mining often requires the clearing of forests, leading to deforestation and the loss of habitat for many species.

Quartz is considered a pure silicate mineral because it is composed solely of silicon dioxide (SiO2). It does not contain any impurities or other elements in its chemical composition. This makes quartz a pure example of a silicate mineral, which is a mineral that contains silicon and oxygen as its main components.

The classifications for a mineral include being an inorganic solid, having a crystal structure, being naturally occurring, and having a chemical composition. These characteristics are essential in defining a mineral. Being light in color or being a liquid at room temperature are not classifications for a mineral as they do not pertain to the fundamental properties that define a mineral.

Quartz possesses special properties such as generating small electrical currents and exhibiting small vibrations. These characteristics make it useful in various applications, including electronics and timekeeping devices. The small electrical currents generated by quartz can be utilized in electronic circuits, while the ability to vibrate at a precise frequency allows it to be used in quartz watches and oscillators. These properties make quartz a valuable material in the technological industry.

Quartz is commonly used in watches as it has a property called piezoelectricity, which means it can generate an electric charge when pressure is applied to it. This property makes it ideal for use in the timekeeping mechanism of watches. Quartz is also used in radio transmitters as it can generate a stable frequency when an electric current is applied to it. Additionally, quartz is used in microphones as it can convert sound waves into electrical signals. However, quartz is not typically used in telescopes or batteries.

The density, chemical make up, and crystal structure of a mineral are dependent upon the arrangement of atoms and the rate of cooling. The arrangement of atoms determines the overall structure and properties of the mineral, such as its hardness and luster. The rate of cooling affects how the atoms come together to form crystals, which in turn affects the mineral's final structure and properties. Therefore, both the arrangement of atoms and the rate of cooling play crucial roles in determining the characteristics of a mineral.

Luster and hardness are both physical properties that can be used to easily distinguish between quartz and talc. Luster refers to the way a mineral reflects light, and quartz has a glassy or vitreous luster while talc has a pearly or greasy luster. Hardness, on the other hand, measures a mineral's resistance to scratching, and quartz is much harder than talc. By testing the luster and hardness of the minerals, one can easily tell them apart despite having the same density and streak.

Metallic bonds are formed between metal atoms and are characterized by the delocalization of electrons. This delocalization allows for the easy movement of electrons, making metals good electrical conductors. Additionally, metallic bonds allow for the atoms to slide past each other, giving metals their pliability. The strong attraction between metal atoms in metallic bonds also makes them resistant to breaking, hence they do not break easily. Therefore, the given answer correctly identifies the properties of metallic bonds.
