Chapter 3, Section 1, “Minerals” 1) All 4000 ____________________ on Earth share four specific characteristics. A) Minerals are ___________________ occurring, that means formed by processes on or inside Earth with no input from humans. For example, ______ formed by the natural evaporation of seawater is the mineral ____________, but if it is formed in a lab it is not a mineral. B) Minerals are _________________ __________, not made by life processes. If you remember, the term ‘organic’ refers to a group of chemical compounds containing carbon that were derived from plants or animals. Minerals are not organic. Example: sugar is NOT a mineral because it is made by plants. C) Minerals are elements or compounds with a definite chemical ____________. D) Minerals have an orderly arrangement of _______________ and all minerals are ____________________ solids. 2) Only a ____________ can be a mineral, but not all _____________ are minerals. 3) The term _________________ means a solid with atoms arranged in orderly, repeating patterns that repeat over and over. 4) A _______________________ is a solid in which the atoms are arranged in orderly, repeating patterns. 5) A crystals shape depends on how its __________________ are arranged. 6) Crystal shapes can be organized into groups known as _____________________. 7) The basic crystal systems are: (fill in examples for all of them!) Crystal Type cubic examples Salt or halite hexagonal tetragonal orthorhombic monoclinic triclinic Quartz 8) Some crystals form from cooling _______________, hot melted rock below the Earth’s surface. We call these types of rocks/minerals ‘INtrusive’. They cool slower because they aren’t exposed to wind, rain, or other environmental factors. 9) Some crystals form from cooling _______________, hot melted rock ABOVE the Earth’s surface. We call these types of rocks/minerals ‘EXtrusive’. They cool faster because they are exposed to wind, rain, and other environmental factors. 10) When magma cools ________________, the atoms have time to rearrange and the crystals are large. 11) When magma cools _________________, the atoms don’t have much time to rearrange so the crystals are small. 12) Crystals can form from ____________________ as the water evaporates or they can form if too much of a substance is dissolved in the water. 13) Crystals formed as water evaporates are called ______________________. 14) 98% of the Earth’s crust is made up of only _______________ elements. 15) Silicates are minerals that contain _________________, oxygen, and one or more other elements; they include most common rock-forming minerals. 16) Silicon and oxygen are the two most __________________ elements in Earth’s crust; they form the building blocks of many minerals. 17) Most minerals are composed of ________________ and _________________ combined with other elements. Chapter 3, Section 2, 1) “Mineral Identification” ___________________ and ___________________ are not enough to distinguish most minerals. 2) The minerals pyrite and gold are both gold colored and may appear similar. Pyrite is often called __________________ __________________. 3) _________________ is a measure of how easily a mineral can be scratched, the _____________________________ compares mineral hardness. 4) The Mohs Scale lists the hardness of __________________ minerals. 5) ___________, the softest mineral, has a hardness of one, and ___________, the hardest mineral, has a hardness value of ten on the Mohs Scale. 6) The way a mineral reflects __________________ is its luster, it can be __________________ or __________________. 8) Nonmetallic lusters include dull, pearly, ____________and ______________. 9) Some minerals with glassy lusters are quartz, calcite, ________ and _______. 10) Specific _______________is the ratio of a mineral’s weight to the weight of an equal volume of ________________ expressed as a ________________. 11) Gold’s specific gravity is 19, pyrite’s specific gravity is 5. Gold is 19 times heavier than ___________, pyrite is ___________ times heavier than water. 12) __________________ is the color of a mineral in powdered form, but the streak test is useful only for minerals _____________than the streak plate. 13) Gold and pyrite can be distinguished by a __________________ test. Gold has a _______________ streak and pyrite has a _______________ streak. 14) The way a mineral ________________can be a distinguishing characteristic. 15) Minerals with ______________________ break along smooth, flat surfaces. 16) Cleavage and hardness are determined by the arrangement of a mineral’s _____. 17) Weak or fewer bonds within the structures of ______________ and _____________ allow them to be broken along smooth, flat, cleavage planes. 18) Minerals with _____________ break with uneven, rough, or jagged surfaces. 19) Quartz is a mineral with ______________________ . 20) Some minerals have properties that involve _______________ or magnetism. 21) _____________ and ______________ will pick up iron filings like a magnet. 22) Calcite causes light to split in two, causing you to see a __________________ image when looking through a transparent specimen. 23) Calcite also fizzes when _______________________ (HCL) is dropped on it. Chapter 3, Section 3, “Uses of Minerals” 1) ________________ are rare and beautiful minerals that are highly prized. 2) _______________________ is a gemstone of quartz that has a purple color. 3) The __________________ diamond and the ________________ diamonds are famous historical gems. 4) The ______________diamond was the largest uncut diamond ever discovered. 5) The __________________ diamond gained a reputation for bringing bad luck. 6) Gems have ______________ applications in abrasives, lasers, and electronics. 7) Diamonds have a hardness of ten on the Mohs Scale so they are very useful as industrial ______________________ or ______________________ tools. 8) Rubies can be used to produce specific types of _________________ light. 9) Quartz crystals are used in _______________ and as _________________. 10) Most industrial diamonds and other gems are ____________________, which means they are made by humans. 11) Minerals can contain other useful ______________________. 12) An ______________ is a mineral or rock containing a substance that can be mined at a profit. Minerals are classified as ores as long as they are profitable and useful. 13) ______________________, an ore of aluminum, is refined to make pure aluminum for many products. 14) Iron, is obtained from its ore ______________________. 15) __________________ is another mineral that contains iron. 16) Elements must be __________________ or purified, from ores. 17) During __________________, a substance is melted to separate it from any unwanted materials. 18) Some elements __________________ in fluids, travel through weaknesses in rocks, and form __________________ __________________ deposits. 19) __________________ , an important source of zinc, sometimes fills spaces in collapsed limestone. 20) ___________________ is the process of coating iron with zinc to prevent rust. 21) Titanium is a useful element derived from the minerals _________________ and __________________. Ilminite and rutile are common in cooled magma, as vein minerals, and as beach sand. 22) ______________________ is a durable, lightweight, metallic element used in automobile body parts, wheel chairs, tennis rackets, and many other products.
