Science quiz
| 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 |
