Rocks and Minerals

What is a mineral?

• A naturally occurring, inorganic solid, that has a definite chemical composition, and a crystal structure. 
• a type of rock that is made of a mixture of things.
• a mineral has streak, luster and a specific color. 
• -

To be formed "inorganically" means that....

• it was formed from once living things like plant and animal material
• it was formed in a lab setting
• it was formed using non-living things but things made within the earth
• you can buy it in the grocery store

Which of the following has the 8 ways we identify minerals?

• streak, cleavage, color, luster, inorganic, solid, density, hardness
• magnetic, crystal structure, hardness, luster, naturally forms, has definite chemical composition
• streak, color, luster, hardness, density, crystal structure, cleavage, fracture

Which of the following is used to determine the hardness of a mineral?

• The Mer Hardness Scale 
• The Mohs Hardness Scale 
• The Merchant Hardness Scale
• The Mercalli Hardness Scale 

A generally light colored rock that has a high silica content is known as 

• quartz
• basalt
• feldspar
• granite 

What is density? 

• volume/mass
• the amount of weight an object holds
• how thick something is 
• mass/volume

How well do you know your teacher: When I was in 6th grade I played percussion in band. Why did I quit? 

• the instrument bag was too heavy back and forth from school.
• I do not have a single musical bone in my body. 
• my sister would beat me home and eat all the good snacks before I could
• I didn't quit, in fact I went on to play in a real band known as "the Chris Brown experiment". 

A  mineral that splits easily along a flat surface has what we call: 

• fracture
• cleavage
• crystal structure
• high silica content 

This type of rock forms from weathering and erosion and is made from fossils:

• metamorphic
• sedminentary
• igneous
