How can you distinguish a rock from a mineral?
A rock is inorganic and a solid naturally-formed substance without any chemical composition or atomic structure. A mineral is also a solid inorganic substance as that of the rock which has a definite crystalline structure as well as chemical composition. See also why did siam become thailand
Can acid rain burn your skin?
Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much much weaker than this it is never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air.
What is the least important property of a mineral?
Color. The most obvious property of a mineral its color is unfortunately also the least diagnostic.
How does mining contribute to land pollution?
Particulate matter is released in surface mining when overburden is stripped from the site and stored or returned to the pit. When the soil is removed vegetation is also removed exposing the soil to the weather causing particulates to become airborne through wind erosion and road traffic.
Why it is important to determine the physical and the chemical properties of a mineral?
Minerals can be identified by their physical characteristics. The physical properties of minerals are related to their chemical composition and bonding. Some characteristics such as a mineral’s hardness are more useful for mineral identification.
Which property of minerals is one of the most reliable tests used to identify minerals?
Streak is a more reliable property than color because streak does not vary. Minerals that are the same color may have a different colored streak.
How can you distinguish an igneous rock from sedimentary rocks?
Igneous rocks can be distinguished from sedimentary rocks by the lack of beds lack of fossils and lack of rounded grains in igneous rocks and the presence of igneous textures.
How would you characterize a metallic mineral quizlet?
Metallic minerals conduct electricity have shiny surfaces and are opaque. Non metallic minerals are insulators have dull surface and you can see through them.
What factors did you consider in selecting where to start mining the rocks?
The location and shape of the deposit strength of the rock ore grade mining costs and current market price of the commodity are some of the determining factors for selecting which mining method to use.
Which of the following properties would be least useful for identifying a sample of calcite?
Which of the following properties would be least useful for identifying a sample of calcite? cleavage. It does not react with hydrochloric acid is a light pink color and has a nonmetallic luster.
What property must a mineral have if it is to be mined by solution mining?
What are three ways we can help minimize the negative impacts of mining and address limited supplies?
What is a mining method used for large ore deposits near the surface that are mined downward?
Large quantities of near-surface ores like coal gold and copper are mined with open-pit mining. In open-pit mining ores are mined downward layer by layer. Explosive are used if needed to break up the ore before it is hauled out by trucks.
Is copper metallic or nonmetallic?
copper (Cu) chemical element a reddish extremely ductile metal of Group 11 (Ib) of the periodic table that is an unusually good conductor of electricity and heat. Copper is found in the free metallic state in nature.
What is the value of a mineral determined by?
There are no exacting standards to determine the value of minerals. With experience one can guess a mineral’s price range by gathering certain information about the specimen. Certain unique properties will set it aside from other specimens of the same type.
What are the effects of the acid water on animals?
The acidity of the water does not just affect species directly it also causes toxic substances such as aluminium to be released into the water from the soil harming fish and other aquatic animals.
How do metallic elements differ from non-metallic elements?
For starters metal elements have high electrical conductivity properties. … Metal elements are also malleable and ductile allowing them to be “worked.” Nonmetal elements have poor electrical as well as thermal conductivity. They aren’t able to pass electricity or heat as well as metal elements.
What is the property of mineral that can be observed directly?

| Hardness | Mineral |
|---|---|
| 1 | Talc |
| 2 | Gypsum |
| 3 | Calcite |
| 4 | Fluorite |
Is copper a mineral?
Copper is a mineral and an element essential to our everyday lives. … Copper is element number 29 on the Periodic Table of Elements.
Which minerals have no commercial value?
As generally used gangue minerals have no commercial importance in a particular period of time possibly becoming ore minerals at a later date. They are commonly silicates carbonates or fluorides more rarely sulfides.
Metallic vs Non Metallic Minerals|Difference between metallic and nonmetallic minerals|
What is one of the most reliable ways to identify minerals?
The ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals.
What property of minerals will you use to identify clear quartz and calcite?
Hardness. Mineral hardness is a key characteristic that scientists use in sample identification. Quartz is about four times harder than calcite. A piece of quartz can scratch a sample of calcite but calcite cannot scratch quartz.
What do you know about minerals?
A mineral is an element or chemical compound that is normally crystalline and that has been formed as a result of geological processes. Examples include quartz feldspar minerals calcite sulfur and the clay minerals such as kaolinite and smectite. … Minerals are often used in the production of ceramics.
How would you characterize a metallic mineral?
Metallic minerals have high malleability and ductility. Non-metallic minerals lack in malleability and ductility and these minerals break down easily. Metallic minerals generally have lustre.
Which of the following is a water contaminant that can cause acid mine?

How can we prevent water pollution from mining?
To mitigate water pollution caused by mining activities measures such as installation of water treatment plants (Effluent Treatment Plant or ETP) for eliminating pollutants from mine water as well as storm water and discharge from the workshops installation of Sewage Treatment Plant (STP) for treatment of effluents …
What other toxins and contaminants can be present in mining waste water?
Heavy metals include: arsenic antimony cadmium chromium copper lead selenium and many more. Heavy metals can contaminate private wells through groundwater movement and surface water seepage and run-off.
