|
inorganic, solid material found in nature that always has the same chemical makeup, atoms arranged in an orderly pattern, and properties such as cleavage and fracture, color, hardness, and streak and luster
|
|
2
|
how a mineral breaks into forms or shapes other than flat surfaces. Jagged or rough edges that a mineral has
|

3
|
rocks that have visible layers or elongated grains of minerals
|
|
4
|
Rocks that do not have distinct layers or bands
|
|
7
|
a type of rock that forms when melted rock materials from inside the Earth cools and on Earth too
|
|
8
|
a model that scientists use to describe how different kinds of rock are related to one another and how rocks change from one type to another
|
|
9
|
describes how a mineral breaks into flat surfaces (usually one, two, three or four surfaces) smooth regular planes that reflect light on a mineral
|
|
11
|
scraping a mineral across an unglazed, white tile, called a streak plate, produces a color that is not necessarily the same color as the mineral itself
|
|
13
|
pieces of broken rock, shells, mineral grains and other materials make up what is called sediment, sediments collect together to form this type of rock

a way of describing how easy or difficult it is to scratch the mineral, Mohs Scale classifies minerals based on this properties
