Waves

what is the distance from A to B

• wavelength 
• amplitude 
• trough 
• crest 

what is J on this diagram 

• crest 
• amplitude 
• trough 
• midpoint 

The measurement from crest-to-crest OR trough-to-trough is called

• amplitude

• wavelength

• frequency

• compression

Which of these BEST describes the cause of waves in the ocean?

• high and low tides
• evaporation of water
• wind blowing across the surface of the ocean
• ridges and trenches on the bottom of the ocean

A tsunami is an unusually large wave caused by

• an earthquake or volcano
• increased gravitational pulls when the sun and moon line up
• a heat wave
• extreme winds   

The two main parts of a wave are?

• Wavelengths and wave heights.
• Swells and whitecaps.
• Crests and troughs.
• Rises and dips.

Why do waves increase in height as they approach the shore? 

• The waves begin to interact with the ocean floor.
• The water’s density decreases because it is warmer near the shore. 
• The wave particles speed up as they approach the land.
• The waves are forced into narrow inlets of land.

What is distance from a wave's crest to the trough called?

• wave height
• wave length
• wave frequency
• wave period
