Waves :)
Molecules in waves

Individual water molecules in waves do not travel in waves, but rather move in circles as the wave passes. The molecules move most on the surface, and the water molecules move in smaller circles as the wave deepens.
Wave movement

Waves don't move water across the ocean, but energy.
Wavelength

The highest part of the wave is called the crest, lowest part is called the trough. The distance between the crest and trough is the wave height. The distance from crest to crest is the wavelength.

Waves are generated by wind.
Max waves

When waves reach the same speed as the wind pushing them, they become larger.
Largest waves

Largest waves are found in open oceans like Antarctica and the Indian Ocean, with less land, the faster the wind will blow creating larger and faster waves.

These are waves that are stacked up behind each other due to wind.
Rogue waves

When wave trains collide with each other, the can become up to 100ft in size.
Shallow waves

Shallow water meets the ocean floor, then when it meets the ocean floor, the wave slows down, shortens wavelength and wave height.
Swash

Swash is the white foam that forms after a wave has crashed.
Tsunami

A wave caused by underwater landslides, volcanic eruptions, astroids landing in the ocean, but mostly, earthquakes.

Warnings for when a tsunami is coming.

Generator designs are being developed that rely on the up and down motion of waves to spin turbines.
Bill Nye: Waves
1. What are three things that travel in waves? Guitar strings, speakers, and televisions.
2. What are three of the properties of waves? Wave length, frequencing, and amplitude.
3. Why does light break into patterns when it is run through thin slits? Because the light travels in waves.
4. Do X-rays have higher or lower frequency than light waves? Higher.
5. Define wavelength: distance between two successive parts that are aligned.
6. What causes waves on the ocean? Wind causes waves in the ocean.
7. What are the waves in the Earth called? Seismic waves.
8. Define frequency: how frequent a wave passes a certain point.
9. Define amplitude: height of a wave.
10. What kind of wave travels by squeezing and spreading? Compression
11. What is it called when a wave bounces and comes back to the source? Sonar.
12. What is sonar? When you send a sound wave and wait for it to bounce back. It determines depth and things near the wave.
