2.10 Ocean Waves

What happens to most of the energy when energy is transferred to ocean water from the moving air above it?

• It moves through the water.

• It pushes the water forward.

• It reflects off the surface of the water.

• It causes the water to evaporate.

What is the relationship between wind and ocean waves?

• Wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

• Wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength.

• Winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves.

• Winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate.

How do water particles in a wave move?

• The particles move forward with the wave.

• The particles move in a circular motion.

• The particles move up and down.

• The particles stay still.

What happens to the water particles in a wave?

• The wave pushes the water particles forward.

• The water particles move in a circular pattern.

• The wind pushes the water particles down.

• The water particles move up through the wave.

Which statement best describes beaches?

• Beaches are always changing due to factors such as waves adding and eroding sand.

• Beaches change little over time as waves follow the same patterns year after year.

• Beaches change over time as waves move further up the shore.

• Beaches change little over time as wind patterns stay the same.

What happens to beaches over time?

• They can change suddenly, such as after a storm, or they can change slowly, such as when high tides erode a shoreline cliff.

• Beaches undergo little change—any sand that is eroded is added back by rivers that flow nearby.

• They only undergo a number of sudden changes when tsunamis hit their shores.

• Beaches undergo little change since any buildup of landforms will be broken apart by the waves.

Which conditions produce the smallest and largest ocean waves? Choose the two correct answers.

• strong winds that blow for a long time over a great distance

• weak winds that blow for short periods of time with a short fetch

• strong winds that blow for short periods of time over great distances

• strong winds that blow for short periods of time over small distances

• strong winds that blow for short periods of time with a short fetch

Which factors play a role in creating ocean waves?

Choose all answers that are correct.

• Wind speed

• Wind direction

• Wind duration

• Wind fetch

• Wind elevation

What is the result of wave motion on water particles?

• Water particles barely move forward; they move in a circular pattern.

• Water particles are pushed down as they move side to side.

• Water particles barely move forward as they move up and down.

• Water particles are pushed forward as they move up and down.

What occurs as energy is transferred through a wave?

• Water particles are set in a circular motion.

• Water particles are pushed forward by the wind.

• Water particles are pulled backwards by the wind.

• Water particles are set in a vertical motion.
