What characteristic of the granite intrusion provides the most evidence that it solidified deep underground?
The size of the mineral crystals in the granite intrusion is the characteristic that provides the most evidence that it solidified deep underground. Slow cooling at depth allows for the growth of large mineral crystals due to the extended period of time for mineral growth.
Which property is the most unreliable variable diagnostic property of minerals such as quartz?
Color is the most unreliable diagnostic property of minerals like quartz because it can be easily influenced by impurities, resulting in varying colors. This makes color alone insufficient for accurate mineral identification.
Which of the following in not a main characteristic of a mineral?
The ability to produce energy is not a main characteristic of a mineral. Minerals are typically characterized by their chemical composition, crystal structure, hardness, and color.
This mineral is the most common iron oxide mineral Most are red with an earthy luster It has a crumbly fracture and leaves a red brown streak?
The mineral described is likely hematite. Hematite is commonly found as red and earthy looking with a metallic to earthy luster. It has a characteristic red-brown streak and often occurs in a crumbly or granular form.
What characteristic is used to determine the color of a mineral's powder?
The characteristic used to determine the color of a mineral's powder is known as its "streak color." This is achieved by scratching the mineral against an unglazed porcelain plate to observe the color of the powdered residue left behind. Streak color can sometimes differ from the visible color of the mineral.
The most obvious but most unreliable mineral property is?
Streak
What is a characteristic property of the mineral pyrite?
The characteristic property of the mineral pyrite is sand it is very shiny
What mineral composition is most characteristic of mafic rocks?
olivine, pyroxene, and calcium-rich plagioclase
What characteristic of the granite intrusion provides the most evidence that it solidified deep underground?
The size of the mineral crystals in the granite intrusion is the characteristic that provides the most evidence that it solidified deep underground. Slow cooling at depth allows for the growth of large mineral crystals due to the extended period of time for mineral growth.
What characteristic of a mineral?
rough, sharp
Which property is the most unreliable variable diagnostic property of minerals such as quartz?
Color is the most unreliable diagnostic property of minerals like quartz because it can be easily influenced by impurities, resulting in varying colors. This makes color alone insufficient for accurate mineral identification.
Which mineral is an ore of iron and has a characteristic of reddish brown streak?
The mineral is hematite.
What is the characteristic of a mineral that is revealed by testing what substances can scratch it and what the mineral can scratch?
it is hardness
Which characteristic is most responsible for the color of different types of rocks?
The mineral constituents of rocks are the major source of their color.
What is an accessory mineral?
An accessory mineral is a mineral present in small amounts in a rock, but not considered to be characteristic of the rock.
Why color is an unreliable clue to the identify of a mineral?
Color alone is unreliable because many minerals come in a variety of colors due to impurities or variations in their chemical composition. This means that different minerals can have the same color, making it difficult to identify them based solely on this characteristic. It is more accurate to rely on other physical properties like hardness, luster, and crystal form for mineral identification.
What are two characteristics of IPv4?
The first characteristic is that the IPv4 is completely connectionless. The second is that they are media independent and can be unreliable.
