Earth's Interior
This is the outer layer of Earth made of solid rock.
What is the crust.
A mineral must always be this state of matter.
What is solid?
This property describes how light reflects.
What is luster?
Rocks are made of these.
What are minerals?
This is the breaking down of rock.
What is weathering?
Earth has these three main layers.
What are crust, mantle, and core?
Minerals form by these types of processes.
What are inorganic processes?
This is the color of a mineral in powdered form.
What is streak?
Particles in rocks are called this.
What are grains?
This moves sediment from one place to another.
What is erosion?
The inner core is this state of matter.
What is solid?
This describes particles arranged in a repeating pattern.
What is crystal structure?
This property is measured using the Mohs Scale.
What is hardness?
This type of rock forms from cooled magma or lava.
What is igneous rock?
This is when sediment is dropped.
What is deposition?
As depth increases, these two things increase.
What are temperature and pressure?
A mineral must be naturally occurring and have this.
What is a definite chemical composition?
Breaking into flat surfaces is called this.
What is cleavage?
This type of rock forms from sediment.
What is sedimentary rock?
This presses sediment together.
What is compaction?
This type of evidence uses seismic waves.
What is indirect evidence?
Name two characteristics of a mineral.
What is: luster, cleavage, fracture, hardness, streak, density, color?
Mass per unit volume is called this property.
What is density?
This type of rock forms from heat and pressure.
What is metamorphic rock?
This process turns rock into magma.
What is melting?
