Related: Waves and Their Applications for Energy TransferModeling Earthquake Waves An earthquake occurs when massive rock layers slide past each other. This motion makes enormous vibrations, which travel from the site of the earthquake in waves. The waves (seismic waves) travel all the way through the Earth.

Lesson Plans On Sound And Acoustics For Grades 4 Through 6 Acoustics is the study of the properties of sound and how sound is transmitted through space. Engineers working on airplane design pay close attention to the acoustics of the airplane cabin in an effort to keep passengers as comfortable as possible. In this module, students develop, test, and modify designs for a quieter airplane cabin.
» Feds To Protect Drug-Dispensing Postal Workers From “Violent Crowds” Alex Jones Paul Joseph WatsonInfowars.com Tuesday, August 3, 2010 Obama executive order contains ominous language about combating Americans who choose to resist martial law takeover after biological terror attack.
