Waves HOT questions: What could be the danger for countries with not enough money during seismic events? Loss of life, unable to detect or repair buildings What about those with more money but also more buildings and technology? Smaller loss of life but greater building damage. Better detection and more able to repair though costly.

Summary/Feedback/Questions Waves can move up/down and side to side There are 4 main ways we can describe a wave Amplitude (Height) Frequency (How many waves hit one place over time) Speed Wavelength (How much time in between) Waves are in many forms Water Seismic (ground) Sound! Light!
