Chapter Test/Test on Minerals
Help!

|

|---|---|---|---|---|---|
| A mineral that is made up of only one element | Native Element
🗑
|
||||
| Minerals that break at random and with rough or jagged edges | Fracture
🗑
|
||||
| Most common mineral found in the Earth's crust | Quartz
🗑
|
||||
| Color, Crystal, Cleavage/Fracture, Luster, Hardness, Streak | Mineral Properties
🗑
|
||||
| Shape of mineral formed by repeating pattern of atoms. Some mineral have well defined crystals (cube, hexagon, etc.) while others are irregular | Crystal
🗑
|
||||
| A mineral lacking both oxygen and silicon | Non-Silicates
🗑
|
||||
| A substance that cannot be broken down into simpler substances by chemical means | Element
🗑
|
||||
| The way the mineral breaks. Minerals break away along smooth, flat surfaces and every fragment has the same general shape. | Cleavage
🗑
|
||||
| The color of the streak can be different from the mineral. The color of the powdered form of the mineral. Minerals must be softer than the streak plate. | Streak
🗑
|
||||
| The number of protons equals electrons | Atomic Number
🗑
|
||||
| The ore is mined from rocks that have not been exposed too weathering in a tropical environment | Bauxite/Aluminum
🗑
|
||||
| Scale from 1 (softest) to 10 (hardest). Test by seeing if the mineral can scratch different objects. | MOHS Hardness Scale
🗑
|
||||
| How easily a mineral can be scratched | Hardness
🗑
|
||||
| A mineral containing both silicon and oxygen | Silicates
🗑
|
||||
| Surface reflection | Luster
🗑
|
||||
| Shiny, like metal | Metallic
🗑
|
||||
| Least reliable test. Many minerals have the same _____. | Color
🗑
|
||||
| A naturally occurring inorganic solid, with a crystal shape that repeats itself, and a definite chemical composition (elements are always the same) | Mineral
🗑
|
||||
| A rock that contains high enough concentrations of a defined substance such as metal, so it can mined for profit. | Ore
🗑
|
||||
| Most abundant metallic mineral | Iron
🗑
|
||||
| Dull, non-shiny, surfaced | Non-Metallic
🗑
|
||||
| Most abundant elements in Earth's crust | Silicon, Oxygen
🗑
|
||||
| Mass/Volume | Density
🗑
|
||||
| Naturally formed, inorganic, crystal-like structure, solid structure, specific chemical composition | Mineral
🗑
|
||||
| All minerals are solids. A solid matter with tightly packed atoms or ions that has a definite shape and volume. | Solid
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
