Motions of the Ocean

Horizontal distance between two wave crests is the 

• frequency
• wavelength
• trough
• wave height

The size of a wave is NOT affected by the

• length of time the wind blows across the water
• salinity of the water
• strength of the wind
• distance the wind blows across the water.

The lowest point on a wave is the

• crest
• trough
• line of origin
• wavelength

Distance from the crest to trough of a wave is called

• wavelength
• line of origin
• wave height
• wave period

A wave will increase in height when the distance over which the winds blow over the ocean

• increases
• stays the same
• decreases
• is 0 km

The highest point on a wave is the

• crest
• trough
• line of origin
• wavelength

In the Northern Hemisphere, currents curve to the right because of the

• longshore drift
• density
• Coriolis Effect
• Moon's gravity.

What is the main cause of Gulf Stream movement?

• Storms
• winds that blow now and then
• winds that blow in the same direction regularly
• the moon's gravity

A major warm ocean current flows along a coastal area.  What type of climate would you most likely find in the area influenced by the current?

• cool and dry
• mild and wet
• extremely hot and dry
• extremely cool and wet

Most currents that flow on the western side of a continent are usually

• warm
• irregular in motion
• cold
• moving toward the poles
