Waves

When energy is transferred to ocean water from the moving air above it, what happens to most of the energy?

• 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?

• Forward

• Circular Motion

• Up and down

• Stay still

Which statement best describes beaches?

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

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

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

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

What happens to beaches over time?

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

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

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

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

Which of the following will produce the largest ocean waves?

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

• Strong winds that blow for long periods of time over small distances.

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

• Strong winds that blow for a long time over a great distance.

What weather would create the weakest surfing waves?

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

• Weak winds that blow for long periods of time with a long fetch

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

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

Which factors play a role in creating ocean waves?

• Wind speed, duration, and direction

• Fetch and wind speed

• Wind speed, direction, and fetch

• Wind speed, direction, fetch, and duration

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.
