Use this model of ocean waves hitting the shore to investigate transfers of energy.

Which statement represents how energy in the waves changes as they reach the shore?

• The energy in waves will be transferred to the rocks and sand.

• The energy in waves will be lost when waves move over the sand.

• The waves will gain energy from the sand and rocks and become larger.

• The waves will stop before hitting the rocks and no energy will be transferred.

In deeper parts of the ocean, water has more room for wave energy to move. What happens to the wave energy as the water becomes more shallow?

Choose word from the drop down menus to correctly identify the transfer of energy by waves. Some words will not be used.

The water is forced​ (a)  

  into the air,​ (b)    the height of the wave.

When the wave reaches the shore, some of the energy is transferred to the air as​ (c)  

  energy.

• higher
• lower
• increasing
• decreasing
• sound
• light

• Jack used energy to do work.

• Jack had no energy and did no work.

• Jack used energy but the refrigerator did all the work.

• Jack used all his potential energy.

A duck floats up and down in the ocean due to a transfer of energy.

Which identifies what causes the duck to move in the pattern shown?

• light from the sun

• the sound of the wind

Carlie designs a computer program that will combine data from many weather stations so she can study energy in wind and ocean waves. How can she design the program to identify where the energy is transferred?

Not all answers will be used.

Wind speed data show that​ (a)    is transferred to ocean waves.

Data on ocean currents show that waves​ (b)   ​​​​​​​ energy over long distances.

When the waves crash onto land, some of the wave energy is transformed into​ (c)  

.

• motion energy
• move
• sound energy
• wave energy
• store
• light energy

• A speed boat races in circles around the lake.

• A teenager swims to shore after an ocean swim.

• A surfer rides back to the beach on his surfboard.

• A dog fetches a ball tossed in a lake and brings it back to the dock.

Which of these is the best evidence of energy transfer between two objects?

• Sound waves move around air particles to reach reach someone's ear.

• Opposite ends of magnets pull toward one another, and like-ends repel.

• A ball floating in a pool has an air leak and begins to sink to the bottom.

• On a pool table, the white ball hits the eight-ball into the corner pocket.
