Hydrology: water cycle & currents

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 is the name of the largest and most powerful surface current in the North Atlantic Ocean? 

• Gulf of Mexico 
• Pacific Steam 
• Gulf Stream
• Atlantic Ocean steam 

What is the name of a climate event that occurs every two to seven years in the Pacific Ocean.  

• La Nina
• El Nina 
• La Nino  
• El Nino

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

• Conduction
• Global Wind Patterns
• Upwelling
• Temperature and salinity

A horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface.

• Gulf Stream
• Global Conveyor Belt
• Surface Current
• Gyre

Cold ocean currents generally come from

• The North Pole 
• The South Pole
• The Equator
• Both Poles

Two types of water currents are

• local and global
• sea and land
• surface and deep
• warm and cold

The amount of dissolved solids present in the water

• salinity
• chlorine
• nitrogen
• density
