Exploring Minerals Chapter 3 Review
True or FalseFriedrich Mohs invented a system to
smelt two kinds of iron ore.
True or FalseA vein is a narrow channel or slab of a
mineral that is sharply different from the surrounding rock.
The purpose of heating iron ore to a very high temp. in a
blast furnace is….1. to cool down the hot furnace2. to heat the iron so that it separates
from other elements3. to eliminate one kind of iron4. to add hematite to final product
Hard, colorful minerals that have a brilliant or glassy luster
are….
1.crystals2.gemstones3.ores4.metals
What is steel an example of?
1.crystal2.gemstone3.ore4.alloy
Why can’t color alone be used to identify a mineral?
1. luster usually hides a minerals color2.only a few minerals always have their
own characteristic color3. the color of most minerals is hidden by
veins4.color & streak are never the same
color
In a process called __________, an ore is melted to separate the useful
metal from other elements in the ore.
1.shaft2.density3. smelting4.mining
The property of ______ is the mass of the mineral sample per unit
volume.
1.halite2.prospector3.density4. inorganic
What kind of mine is used when ore deposits occur in
veins?1.prospector2. shaft3.ore4.quartz
A rock that contains a metal or useful mineral is called what?
1.halite2.quartz3.ore4.pyrite
True or FalseA miner is anyone who searches for an
ore deposit.
True or FalseMinerals form when hot water solution
cools & the minerals crystallize.
Could you tell samples of minerals apart just by using a scratch test?
Why or why not?
Why is pyrite known as “fool’s gold”?
The size of a mineral’s crystals depends on which of the following?
1. the rate of cooling of magma or solution from which mineral is formed
2. the smelting process in which magma is formed
3. the solution from which mineral formed
4. the mineral’s crystal group
Which is NOT one of the 6 types of crystal shapes?
1.cubic2. triclinic3. tetragonal4.metallic
How do minerals form?
What characteristics does a piece of quartz have
that can be used to classify it as a mineral?
True or FalseSlag is a combination of impurities in
iron ore & limestone. It forms in a blast furnace once the iron in iron ore has melted & sunk to the bottom of the
furnace.
True or FalseThe vast majority of minerals are
compounds.
Wage Time!Prospectors have discovered a halite
deposit near the Great Salt Lake in Utah. Describe how that deposit might have
formed.
