What is the volume of a mineral sample?
Handle your samples to get an idea of how dense each one is, or how heavy each mineral feels for its size. The mass of each sample is measured using a balance or electronic scale. The volume of each sample can be measured (in milliliters) by the amount of water displaced by the sample in a graduated cylinder.
What are silicates give an example?

What are the types of silicates?
TYPES & CLASSIFICATION OF SILICATES
- Ortho silicates (or Nesosilicates)
- Pyro silicate (or Sorosilicates)
- Cyclic silicates (or Ring silicates)
- Chain silicates (or pyroxenes)

Is normal ice a rock?
Rocks are composed of one or more minerals. So, any naturally occurring ice, the crystalline form of water (H2O), can be considered a mineral. Now coming to the concept of glaciers, the glacial ice, like granite, can be considered a rock.

Is coal man made?
Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. The coal we use today took millions of years to form. That is why coal is called nonrenewable.
How can you classify minerals?
Using Characteristics of Minerals to Identify Them. Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
What are the 14 trace elements?
The concentrations of 14 serum trace elements, namely iron (Fe), copper (Cu), zinc (Zn), rubidium (Rb), selenium (Se), strontium (Sr), molybdenum (Mo), manganese (Mn), lead (Pb), arsenic (As), chromium (Cr), cobalt (Co), vanadium (V), and cadmium (Cd), were determined by high-resolution inductively coupled plasma mass …
How do you fix a mineral deficiency?
Certain mineral deficiencies cannot be treated with diet alone. You may be required to take a multivitamin or mineral supplement. These may be taken alone or with other supplements that help the body absorb or use the mineral. Vitamin D, for example, is usually taken along with calcium.
