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.
