Minerals 1

100

The measure of whether a mineral will scratch or be scratch is known as this.

 hardness

200

These are the three types of rocks.

 igneous, sedimentary, and metamorphic rocks

300

This type of igneous rocks has small crystals.

 extrusive

400

This is the color of a mineral’s powder.

streak

500

How do you classify igneous rocks?

Name 3 ways 

• Arrangement and size of mineral crystals 

• Mineral composition in the rock

• Location where lava or magma cools 

• Cooling rate 

Minerals 2

100

In this, the atoms are arranged in a regular, repeating pattern.

crystal

200

This is when mineral composition and texture of a rock changes due to heat and pressure.

Metamorphic Rocks

300

What is cementation? 

When the sediments are held together because minerals crystallize between sediments. 

400

This one of the physical properties of mineral that is related to mass. 

Density 

500

This is a naturally formed, collection of mineral and grains in a firm, solid mass.

Rock

Minerals 3

100

This type of igneous rocks has large crystals.

 Extrusive Rocks 

200

what rock is formed from compaction and cementation? 

Sedimentary Rocks

300

This is a tendency of a mineral to break along certain planes to make smooth surfaces.

 cleavage

400

This is one of the steps that leads to the formation of sedimentary rocks. It needs water, wind, ice to do this so that other processes can be done to make sedimentary rocks. 

Deposition 

500

This is a reference for mineral hardness. You can find a mineral's hardness with this. 

Moh’s Hardness Scale

Minerals 4

100

This group of minerals have two of the most common elements on earth's surface. 

silicates

200

What determines the shape of minerals? 

the arrangement of atoms or ions 

300

These two steps are required for sedimentary rocks to form.

Compaction and cementation

400

This naturally occurring substance is an inorganic crystalline solid with a specific chemical composition.

mineral

500

Tectonic Activity causes the minerals to break down?

T/F

False: It STARTS the process, BUT the minerals are broken down because of HIGH TEMPERATURE AND PRESSURE. Not because the plates move.

Minerals 5

100

_______________ is a type of sedimentary rocks which is made up of mineral and rock fragments.

Clastic Rocks

200

This is the reflection of light off a mineral’s surface.

 luster

300

This process wears rocks down into smaller pieces.

weathering

400

This is the transport of sediments from one place to another using wind, water, ice. 

Erosion

500

Name all three ways minerals are made.
