Light is a form of
energy
200
Amount of water vapor in the air

200
What is th lithosphere?
The crust and upper portion of the mantle
300
What is a hypothesis?
An educated guess to explain the scientific question
300
Which system delivers electrical signals around the body?
The nervous system
300
What happens to particles when they gain energy?
They move faster and spread apart
300
All human eye sight is based on
light
300
Why do hailstorms occur in warm weather?
Warm air must create strong updrafts to carry water into high into the atmosphere
300
Where is new oceanic crust formed?
At mid-ocean ridges and divergent boundaries
400
What is the variable you manipulate, control, or change in an experiment?
The independent variable
400
What is the largest organ of the human body?
The skin
400
What type of heat transfer is being shown?
Conduction
400
What is refraction?
Light bending as it passes through a different medium
400
What creates the largest convection currents?
Large temperature differences between the surface temps and air temperatures
400
What is the asthenophere?
The semi-solid portion of the mantle which tectonic plates move on top of
500
Where do you record the results of your experiments?
In a data table
500
What is the boundary of the cell that lets things in or out of the cell?
The cell membrane
500
How does thermal energy mainly move in fluids?
Through convection currents
500
What is the purpose of the optic lens?
Use refraction to focus light on the back of the eye (retina)
500
Explain why we need water vapor, cold temperatures, and cloud condensation nuclei to form clouds.
Water vapor - clouds are made from water droplets
Cold temperatures - to force water vapor to condense into water vapor
Condensation nuclei - water droplets must condense onto a solid surface

What are two things subduction can cause?
A volcano and trenches
