Understanding Wave Energy

The video explains how wind energy contributes to wave formation. Wind blowing over water creates friction, causing parts of the water to move and form waves. As waves approach land, they grow larger and eventually crash onto the shore.

What is the primary source of energy for waves?

• The Wind

• The Earth's Rotation

• The Moon

• The Sun

What percentage of the Earth's surface is covered in water?

• 60%

• 80%

• 50%

• 70%

What causes the initial spinning motion in water that forms a wave?

• Earthquakes

• Friction from wind

• Tides

• Underwater currents

What happens to the water as waves get closer to land?

• It evaporates

• It freezes

• It becomes still

• It moves up and down on the surface

What eventually causes waves to crash on the sand?

• The spinning effect

• The temperature of the water

• The presence of marine life

• The depth of the ocean
