| Im so confused about earth science . i can never remember the diffrence between P waves and S waves. | |
 | |  |
|
 |
| | |
| oh its not hard P waves are like a slinkey; they alternatley compress and expand. | |
| | |
|
|
|
|
|
|
|
| | |
| ah well i do know what a slinkey looks like. | |
| | |
|
|
| | |
| And S waves are like a rope when you shake it. the wave moves from begining to end. | |
| | |
|
|
|
|
|
|
|
| | |
| so basicly P waves move in and out and S waves move up and down? | |
| | |
|
|
| | |
| Um yes i think so but we better ask Mr. krantz. | |
