The variable that is totally dependent on the independent variable.
The variable that changes as a result of the independent variable changing.
What is a dependent variable
200
When two objects begin to move closer...
the force of gravity increases
200
Streak, luster, cleavage and fracture, hardness, and density
What are the mineral properties that identify a mineral?
200
Igneous, sedimentory, and metamorphic rock
What the three rocks of the rock cycle?
200
All of the plant and animal life on Earth.
What is the biosphere
300
When all the shots are close to the target in no specific pattern
What is Accuracy
300
As the distance of two objects increases...
the force of gravity decreases
300
Occurs naturally, is inorganic, cyrstaline structure, and has a consistent chemical composition.
What are the four criteria for a mineral?
300
If a rock has large crystals you can assume that…
The rock cooled slowly allowing time for the crystals to form into large crystals
300
The blanket of gases that surround the Earth
What is the atmosphere
400
when your shots are bunched together on the target away from the bull's eye
What is precision?
400
Only energy is exchanged
What is a closed system
400
a property that can be observed without changing its chemical properties
What is physical property
400
If a rock has small crystals you can assume that…
The rock cooled too quickly and hardened before the crystals could become any larger
400
All of the liquid water on earth
What is the hydosphere?
500
This action is the scientific community Assures that only well supported ideas and experiments are published.
Checks other scientists’ work to ensure the experiment is repeatable and valid.
Assists in correcting and improving experiments and valid data
What is Peer review
500
both energy and matter are exchanged
What is an open system
500
How a substance reacts with other substances
What is chemical property?
500
Is a metamorphic rock intrusive or extrusive and why?
Intrusive because that is where the rock can undergo metamorphosis through heat, pressure, and chemical changes
500
All of the solid and molten rock that makes up the earth
