Rock Types
What are the three types of rocks?
This mineral can cut ALL other minerals/ what number is it on the MOH's hardness scale?
Diamond
#10
This is the physical property of some minerals that causes them to break with uneven, rough, or jagged surface.
Fracture
The way a mineral reflects light from its surface
Luster
This is the tendency of a mineral to break a long flat surfaces
Cleavage
_________________ forms when MAGMA hardens.
- No Fossils
- Most abundant type in Earth's crust
Igneous
While at the beach, Robby collected a pile of rocks. How could Robby find out whether the rocks contain the same minerals?
Comparing their colors
A solid in which the atoms are arranged in a pattern that repeats again and again
Crystal
This is simply the COLOR of a Mineral's POWDER
Streak
It is naturally occurring, Inorganic, solid that has crystal structure and a definite chemical composition
Mineral
_______________ forms when LAYERS are PACKED & HARDEN.
- Has Fossils
- Contains Layers
- Form near water source
Sedimentary
Pyrite is a common mineral. Like many minerals, scientist can identify pyrite by its INTERNAL REPEATING PATTERN, also called _______________ ____________________.
Crystal Structure
Mass divided by Volume = ____________
_____ = M/V
Density Formula
D
Lucy saw small CRYSTALS shining in the sunlight on the surface of a mountain slope. These were most likely _____________.
Minerals
What would a rock look like that is uniform and has few minerals in it??
One color
_________________ Rocks that are changed by HEAT & PRESSURE.
- Formed from any 3 Rock types
- Heat and pressure
- Forming new mineral withOUT melting
Metamorphic
What are the 5 characteristics of Minerals
2. Inorganic
3. Solid
4. Crystalline Structure
5. Definite Chemical Composition
The scale ranking 10 minerals from SOFTEST to HARDEST; used in testing the hardness of minerals.
MOH's Hardness Scale
ROCKS:
1. Can be any shape
2. Can be one of three kinds
MINERALS:
1. the same throughout
2. ?
Made of just ONE substance
Which types of rocks are LEAST likely to break?
Rocks that are difficult to scratch
This example of sedimentary rock is formed when Rock fragments, minerals, and the remains of plants and animals are deposited as sediments and are then _____________ & _____________ ______________.
Compacted & cemented together
What are the 6 ways to test a mineral (think mineral lab)
1. Color
2. Streak
3. Luster
4. Cleavage/Fracture
5. Hardness
6. Density
This means NOT formed from living things or remains of living things. Does NOT contain carbon.
Inorganic
What types of rock is marble?
Metamorphic rock
How would you BEST describe the concept of rock cycle?
- Any type of rock maybe transformed into another type by the correct process
