The lowest point is called the trough. The distance from one crest to the next is the wave length. The number of waves that pass a given point in one second is the wave's frequency. When wind blows over the ocean's surface, it creates waves. Their size depends on how far, how fast and how long the wind blows.
6. What causes waves on the ocean? Wind causes waves on the ocean. 7. What are the waves in the Earth called (Earthquake waves)? The waves in the Earth are called seismic waves. 8. Define frequency. Frequency is how fast a wave travels. 9. Define amplitude. Amplitude is the height of the wave. 10. What kind of wave travels by squeezing and spreading? (Give an example). Compression waves travel by squeezing and spreading. 11. What is it called when a wave bounces back and comes back to the source? It is called an echo or a reflection when a wave bounces back and comes back to the source. 12. What is sonar? Sonar is using sound waves to tell how far something is.
