3 types of rocks
100
What does inorganic mean?
What is non-living
100
Is color alone a way to ID a mineral like pyrite or gold?
What is no---pyrite and gold are both gold color but have different properties and densities and uses
100
What is the process of finding a mineral's density?
What is find the mass by a balance scale and then find the volume using a graduated cylinder---then divide mass by volume
100
Name the 3 ways minerals form
What is organic processes, crystallize from materials dissolved in solutions, as magma and lava cool
100
What are the 3 types of rock?
What is sedimentary, metamorphic, igneous
200
True or false....some minerals can form from organic and inorganic processes
What is true
200
What is the streak of the mineral?
What is the color of the powder
200
The mass of a mineral is 15 grams.....the volume is 3 cm3...what is the density?
What is 5 g/cm3

Explain how a geode forms
What is crack in a rock forms, water with dissolved minerals seeps into the rock, the water evaporates leaving the mineral crystals, geode is formed
200
a rock is changed from one type to another by great pressure or temperature....what type of rock is it?
What is metamorphic
300
Give me an example of definite chemical composition
What is quartz has one atom of silicon for every 2 atoms of oxygen, garnet has 3 atoms of silicon for every 12 atoms of oxygen
300
The term that means.....how light is reflected from a mineral's surface
What is luster
300
what is crystal structure? can you give an example
What is the shape of the crystals in a mineral....halite are cubic, quartz are prisms
300
What word means....a narrow channel or slab of a mineral that is different from the surrounding rock
What is vein
300
Pumice is a rock formed from molten material......what type of rock is pumice?
What is igneous
400
Amber is made from the process of tree resin hardening into stone....is amber a mineral? Why or why not?
What is no--that's an organic process
400
How is hardness tested?
What is scratch test
400
What word means.....a mineral that splits easily along flat surfaces?
What is cleavage
400
What is the difference between magma and lava?
What is magma is inside the volcano and lava is outside on the surface
400
sandstone forms from layers of dead plant and animal material compressing together over millions of years...what type of rock is sandstone
What is sedimentary
