How is WIND produced? By when light energy from the sun transforms to heat energy and heats the air
What does an initial disturbance do to the water? Vibrations carry the energy away from the source
What do ALL waves have in common? They all transfer energy
True or false: Water waves require a medium? TRUE!!!!
How are ALL waves formed? By a disturbance or vibrations
How is wind created? CONVECTION
In what direction do waves expand? Outward!!!
Can water waves bounce? YES
True or false: Water waves are NOT able to transfer energy to other objects? False.
What does water waves do when they come in contact with other objects? They reflect and refract
What happens when tectonic plates push against each other? Energy builds up
What do seismographs measure? They measure earthquakes
What can seismic waves cause? Tsunamis and earthquakes
What does the richter scale measure? Magnitude
How is magnitude calculated? From amplitude
What does the Mercali scale measure? The intensity of earthquakes
How are seismic waves produced? By vibrations
Where do seismic waves travel through? The earth
When do earthquakes occur? When two poles push against each other and pressure builds up causing the earth to shake
