Light & Matter
This is a form of energy that allows us to see objects.
Light
The rapid back-and-forth motion of particles in an object.
Vibration
The force that pulls certain objects toward a magnet
Attraction
The rise and fall of ocean water levels caused by the moon
Tides
These blood cells carry oxygen throughout the body
red blood cells
When light bounces off a surface.
Reflection
The measurement of a sound waves height
Amplitude
The force that pushes two magnets apart
Repulsion
This eclipse happens when the moon blocks sunlight from reaching earth
Solar eclipse
This part of blook helps form clots and scabs
platelets
This word describes a material that light can pass through, like glass.
Transparent
The number of times a sound wave repeats each second
Frequency
A magnet made by running electric current through a coil of wire around iron
Electromagnet
This eclipse happens when Earth blocks sunlight from reaching the moon
Lunar Eclipse
The process that drives the movement of tectonic plates
Convection currents
Light passing through a window is an example of this process.
Transmission
If a drummer wans a louder sound, they should do this
Apply more force
A circuit where electricity can flow continuously
A Closed Circuit
As the distance between two objects increases, gravitational force does this
Transform Boundary
Explain why you can see your reflection in a mirror.
light reflects off you, bounces off the mirror, and enters your eyes
Compare amplitude and frequency. What does each affect?
amplitude affects loudness and frequency affects pitch
Two north poles are pushing very close together. What will happen and why?
They will strongly repel because the same poles repel and the closer they are together, the more force they will repel with.
A planet with greater mass has this type of gravitational force compared to a smaller object
A greater gravitational force
Alfred Wegener used these three pieces of evidence to support continental Drift
