What is Talc?
The sedimentary environment where coral reefs are found.
What is a marine environment?
A mineral that exhibits ionic bonding.
What is halite?
Something found in rocks that has lasted from a living thing from long ago.
What is a fossil?

What are metamorphic rocks?
Minerals are defined as found in nature. (Part of the definition of a mineral.
What is naturally occurring?
scratched by a nail, white or clear, rhombohedral shape, bubbles with weak acid
What is calcite?
In this type of bonding, electrons are donated to another atom.
What is ionic bonding?
This mineral is hard because it has this type of bonding.
What is covalent bonding?
A solid material made up from 1 or more minerals
What is a rock?
Found near volcanoes
What are igneous rocks?
In the deinition of a mineral, it states minerals have never been alive.
What is inorganic?
Scratched by a fingernail, black/dark gray or brown, vitreous, can be torn apart in sheets
What is Biotite? (a type of mica)
Forms in Sedimentary rocks because of the layers that bury dead plants and animals
What are fossils?
This atom has 6 protons and this many electrons ____ (Looking for a number.)
What is 6?
Rock that is formed by lava and magma cooling and hardening.
What is an Igneous Rock?
We classify most rocks using these two types of properties. (Think of the red chart.)
What are texture and composition?
The hardest mineral is_________
What is diamond?
describing a rock as glassy or dull is describing the rock's_______________
What is Luster?
This process of forming igneous rocks that would destroy fossils found in sedimentary rocks.
What is melting?
In the mineral halite, NaCl, the Na has lost an electron when it bonded with Cl so is now called a(n) ______.
What is a cation? (Sodium (Na) has fewer electrons (or fewer negative charges) when it gave an electron to Cl (chlorine). Fewer electrons in the sodium atom means it has a more positive charge. A positively charged atom is a cation.
To be a mineral, it needs to be naturally occurring, have a definite chemical composition, have atoms arranged in patterns (has a crystal structure), be organic and be ______.
What is solid?
Three types of Rocks
What are Sedimentary, Igneous, and Metamorphic?
Name of the scale used to name hardness of minerals.
What is Moh's Hardness Scale?

What is Hardness?
1 way rocks and minerals are different
minerals have crystal structures (rocks do not)
rocks are made of minerals (minerals are not made of rocks)
This mineral is strongly bonded within sheets but weakly bonded between the sheets.
What is mica?
