Waves can be measured in many different ways. Even though waves have different parts to them they all must have the following

• Need a medium
• Move matter
• Need energy to start them and transfer energy with them
• A frequency that is higher than resonance

How do surface ocean waves form? 

• Wind blowing across the surface
• Time wind blows
• Strength of the wind 
• Wind when blows upwards off the water

Currents that are far beneath the surface

• deep ocean currents
• surface currents
• current
• global winds

What process brings nutrient rich deep cold ocean water up to the surface?

• Conduction
• Global Wind Patterns
