What is a Compound?
A Compound is when two or more elements combine.
Example: Cinnabar (made up of Sulfur and mercury
What is a Fracture?
What is Cleavage?
A Fracture describes how a mineral looks when it is split apart in an irregular way.
Cleavage is when a rock cuts through a mineral cleanly.
What is a Metamorphic rock.
A Metamorphic rock forms when a rock is changed by heat pressure. Most form underground.
What is a Liquid?
A liquid is a substance that flows. It has no definite volume.
what is Volume?
The amount of space that matter takes up.
What is a Sedimentary rock?
This rock contains particles of living things that are very slowly deposited by wind or water, layer after layer after layer over many years.
Metamorphic rock is classified into two groups. They are.....
Foliated and Nonfoliated
What is texture?
Texture is how a mineral looks/feels.
Two types of grain shapes?
Rounded and Jagged
What is a Solid?
A Solid is a shape. It has a definite volume.
Some uses of Metamorphic rock
Marble and Slate
Marble is used for buildings, skyscrapers, countertops, old stairs, tower of Pisa.
Slate is used for Celling ties, flooring, stepping stones.
when Igneous rock cools rapidly it produces ______ sized crystals.
Small
What is a Streak? What is a luster?
A Streak is the color of a mineral's powder.
A luster is how the sun reflects on a mineral.
when Igneous rock cools slowly it produces ______ sized crystals.
Large
What is a Geode?
A Geode is a rounded hollow rock lined with mineral crystals.
Igneous rock forms from......
Lava (Extrusive) or Magma (Intrusive)
Banded/Foliated vs Nonbanded/Nonfoliated
Banded/Foliated is when the rocks have bands lines in it. Nonbanded/Nonfoliated rocks don't have a pattern of lines.
Example of a sedimentary rock is...
Sandstone, limestone
What is a Solution?
A Solution is when elements mix. Ex. Salt water. Salt water is a solution because the water evaporates and salt crystals are left behind.
Why can we not rely on the color of a mineral?
There are too many minerals that have the same color.
Uses of rocks....
Obsidian
Pumice
Granite
Obsidian is used for spearheads
Pumice is used for cleaning
Granite is used for buildings
How does a Geode form? Where are they found?
A Geode forms by a volcanic rock that gets hollowed out and then water keeps going in and coming out. Slowly the water leaves behind minerals that form crystals. They are normally found by where volcanos were once.
What is the rock cycle?
The Rock cycle is a process where one type of rock changes into another, creating a new rock. (It takes many years)
Igneous to Sedimentary to Metamorphic
This type of sedimentary rock is composed of rock fragments squeezed together?
Clastic
What happens if we take out a portion of the Rock cycle? Lets say we take out Sedimentary Rock....
The Rock Cycle is a system. If one thing is missing/out nothing will work. If Sedimentary was missing no new rocks.
