Question | Answer |
How are waves on water produced? | Wind/disturbances |
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 |
How do scientists determine the size of earthquakes? | Magnitude and intensity |
