Minerals
What is a mineral?
A mineral is an inorganic solid, found in nature who chemical make up
Igneous
True or False? All rocks can turn into any other rock, in any order.
TRUE!
_______ consists of 2 or more minerals.
Rocks
The Mohs scale measures what of a mineral?
Hardness
What is one thing we use minerals for?
Sedimentary
What causes rocks to break off into pieces of sediment?
Weather and Erosion
These can be cut, polished. They are also rare, which makes them worth money.
Gems
When you enter science class, explain to me what you should do.
For an extra 50 pts- how do you know what we are doing in class that day?
We should sit down, read the smartboard, and begin our bell ringer.
Extra points- this is written on the "agenda" for the day located on the smartboard.
What makes a mineral considered a crystal?
Minerals with atoms arranged in a repeating pattern.
Will consider for 100 points: have a smooth surface, sharp edges with points.
When heat and pressure are applied to rocks and minerals _____________ rocks form.
Metamorphic
When a sedimentary rock is pushed below the earth, and heat and pressure are applied, what type of rock does it turn into?
Metamorphic Rock
This vocab term describes a mineral being useful, and sold for profit.
An Ore
If an igneous rock is melted, and then cooled again, what type of rock is it?
Igneous
What is Not a mineral?
gold, ice, sugar, quartz
This type of igneous rock cools above the Earth's surface.
Extrusive Igneous Rock
If you are standing at the base of a volcano, which type of rock are you most likely to find?
Igneous
The process in which one type of rock can turn into another is called:
The rock cycle
In our starburst rock cycle lab, when we placed the starburst in warm water, what were we starting to represent in the rock cycle?
We were applying heat, to begin the process of creating a metamorphic rock.
Name 5 identifying characteristics of minerals
Streak, luster, cleavage, fracture, hardness
This type of igneous rock cools below the Earth's Crust.
Intrusive Igneous Rock
True or False: Does a volcano need to erupt in order to make an igneous rock?
False-lava can cool within the earth. Or there can be cracks in the earth and magma oozes out.
Usually made with two or more minerals.
Rocks
In the crystal lab we did in class, explain why crystals form when the water cools.
The colder the water, the less amount of minerals the water can hold. The water then releases the minerals and they make crystals.
