Without this process, there would be no fresh drinking water in nature.
What is the hydrological cycle?
100
The 4 main gaseous components of the atmosphere (exclude water vapor).
What are nitrogen, oxygen, carbon dioxide, and argon?
100
When an object travels a certain distance, and also in a certain direction.
What is displacement?
100
When a force acts on an object and moves it a certain distance
What is work?
100
This type of material allows some flow of electricity, examples includes circuit boards, solar panels, electronics, diodes, and transistors.
What are semi-conductors?
200
This property of water causes water molecules to stick together and results in surface tension
What is cohesion?
200
This gas, while essential for plant respiration, is slowly warming the earth by trapping heat, commonly known as the greenhouse effect.
What is carbon dioxide?
200
When a driving force causes an object with mass to move, this happens.
What is acceleration?
200
Assuming that mass and the acceleration of gravity are constant, this dependant variable is directly proportional to gravitational potential energy.
What is height?
200
Measured from the rest position to either a trough or crest of a transverse wave.
What is the amplitude?
300
Factories often use water inside of the smokestacks to trap particulates because of this property of water.
What is adhesion?
300
These chemical compounds were responsible for the destruction of the ozone layer until they were banned.
What are CFCs?
300
Gravity is directly proportional to the objects' mass and inversely proportional to this
What is the square distance?
300
Assuming that mass remains constant, this dependant variable is directly proportional to kinetic energy.
What is velocity?
300
The flow of electrons, measured by taking the potential difference (voltage), and dividing by the resistance.
What is current?
400
This property of water allows fresh water fish to live beneath frozen lakes
What is density? (Solid ice is less dense than liquid water)
400
These energy resources are usually mined, and can not be easily replaced once they are burned.
What are non-renewable energy sources?
400
These forces act over very small distances but have huge amounts of energy assoiated with them
What are nuclear forces (weak and strong nuclear)?
400
The rate of doing work or spending energy.
What is power?
400
A 110 volt light fixture with 0.545 (A) of current uses this much power.
What is 60 (W)?
500
Water made in a factory by electrolysis, distillation, or reverse osmosis.
What is desalination?
500
These energy sources are driven by naturally occurring processes on earth, including solar, wind, and hydroelectric.
What are renewable resources?
500
The slope of a velocity vs time graph (hint: use the definiton of slope and the units to determine this)
What is acceleration?
500
The sum of the kinetic and potential energy at the start of motion is equal to the sum of the kinetic and potential energy at the ending point of measurement.
