A minerals must be INORGANIC, or not made of living things.

What is the difference between magma and lava?
Magma is underneath the Earth's surface and lava is above the Earth's surface. They are both forms of liquid, molten rock.
100
What are the little pieces of rocks, pebbles, mineral grains, or rock fragments called?
Sediments
100
Metamorphic rocks form (above or below) the Earth's surface.
Metamorphic rocks form BELOW the Earth's surface.
100
What is the hardest mineral?
Diamond
200
What is the property that describes the way light reflects off of a mineral?
Luster
200
I form when magma slowly cools underneath the Earth's surface, what am I?
Intrusive igneous rock
200
How are sediments created and transported?
Weathering and Erosion
200
What two processes have to occur in order for a sedimentary rock to form a metamorphic rock?
Heat and Pressure
200
If fossil A is found ABOVE fossil B, which one is probably younger?
Fossil A
300
What is the name of the property you look at when you rub a mineral against a ceramic plate?
The streak
300
I form when lava cools quickly above the Earth's surface, what am I? What size grains do I have?
Extrusive igneous rock, small/no grain size
300
Name the five steps it takes for extrusive igneous rocks to form sedimentary rocks
Weathering, Erosion, Deposition, Compaction, Cementation
300
How can a metamorphic rock turn into a sedimentary rock?
The metamorphic rock would have to be weathered and eroded into sediment, then deposited, compacted and cemented into sedimentary rock.
300
Name 2 ways that rocks are classified.
Rocks are classified by grain size, texture, and how they formed (origin)
400
When you try to scratch a mineral with a nail, a penny, and other objects, what property are you testing? If a mineral ranks a 9 on the Moh's scale, is it hard to scratch or easy to scratch?
The hardness, if it ranks a 9 then the mineral is very hard to scratch.
400
Name one intrusive igneous rock and one extrusive igneous rock that we learned about.
INT: Granite EXT: pumice, scoria, obsidian
400
Why can't fossils be found in igneous rocks?
The magma or lava would disintegrate or dissolve the organic remains instantly.
400
What type of rock was Gneiss before it underwent heat and pressure?
Granite (an igneous rock)
400
What is the mineral that causes a bubbling reaction when acid is added to it?
Cabronate - a compound found in Calcite!
500
How are the atoms in a mineral arranged?
In a crystalline (lattice) structure
500
What size crystals form in intrusive igneous rocks? Why?
Intrusive igneous rocks have LARGE crystals or grains. The form like this because magma takes a LONG time to cool. The longer the time the magma/lava has to cool, the more time is allowed for minerals to line up accordingly.
500
How are fossils formed in sedimentary rock? Walk through each of the five steps of sedimentary rock formation process.
Sediments are weathered off of rocks and eroded. As they deposit on the ground, an organism can die and become buried in the sediment. Over time, more sediments pile up and compact, then cement; creating sedimentary rock.
500
When does the rock cycle end?
Never! Rocks are continuously changing from one type into another.
500
How do fossil fuels form?
Fossil fuels form when organisms die and their organic material collects and creates coal, oil, or natural gas.
