30s - Q7
True or False. 90% of rock-forming minerals belong to Oxides.
False
True
30s - Q8
What property of mineral refers to the external shape of a crystal or groups of crystals is displayed?
Crystal Form
Streak
Cleavage
Density
30s - Q9
What property of mineral indicates how many times more the mineral weighs compared to an equal amount of water?
Density
Cleavage
Specific gravity
Temperature
30s - Q10
True or False. Cleavage exist because the bonding of atoms making up the mineral happens to be weak in those areas.
False
True
30s - Q11
True or False. Individual minerals can also display a variety of colors resulting from impurities and also from some geologic processes like weathering.
True
False
30s - Q12
True or False. The color of the mineral is the same with its streak.
True
False
30s - Q13
True or False. Minerals are the basic building blocks of rocks.
True
False
30s - Q14
Which of the choices is a disadvantage of using Mohs' Scale of Hardness?
The test is easy.
The Scale is qualitative, not quantitative.
The test can be done anywhere, anytime, as long as there is sufficient light to see scratches.
The test is convenient for field geologists with scratch kits who want to make a rough identification of minerals outside the lab.
