Qualitative and Quantitative
What are the two kinds of observations?
100
Density is the measure of the amount of mass per unit of volume.
What is density?
100

What are the three main layers of the earth?
100
Outer zone of the earth; includes the crust and the mantle.
What is the lithosphere?
100
Earthquakes
What is the cause of seismic waves?
200
A statement describing a fact.
What is an observation?
200
grams/centimeters squared
Scientists often measure density in?
200
Continental and Oceanic.
What are the two kinds of crust?
200
zone below the lithosphere; includes the remaining mantle.
What is the asthenosphere?
200
Seismographs
What tool do we use to detect seismic waves?
300
A statement based on an interpretation of facts.
What is an inference?
300
Density is often compared to the density of pure water which is measured in grams/cubic centimeters.
Density is often compared to the density of what which is measured in what?
300
Inner and Outer

300
Asthenosphere
What zone is a semi-liquid zone
300
P Waves
Which kind of seismic waves are faster?

Quantitaitive uses math and Qualitative uses your senses.
What is the difference between qualitative and quantitative observations?
400
Increase mass decrease volume(Increase) Decrease mass increase volume(Decrease)
What causes density to increase and decrease?

What are the kinds of rocks found in the continental and oceanic crust, and where are they found?
400
Lithosphere
What zone floats on top of another zone?
400
Refraction
What is the process called that makes waves move in a curved pattern?
500
An observation is a statement describing a fact and an inference is a statement based on an interpretation of facts.
What is the difference between observations and inferences?
500
Objects with density less than 1g/cubic centimeter will float and objects with density greater than 1g/cubic centimeter will sink.
What causes objects to sink and float?
