Wave Refraction and Mavericks Waves

The video tutorial explains wave refraction, a process where waves slow down and change direction in shallow water. This causes energy concentration near headlands, leading to larger waves and erosion. The Mavericks wave in Northern California is used as a case study to illustrate these concepts, highlighting its formation due to refraction and its reputation as a world-famous surf spot.

What happens to waves as they enter water shallower than the wave base?

• They maintain their speed and height.

• They disappear completely.

• They slow down, bunch up, and grow taller.

• They speed up and spread out.

What is wave refraction?

• Waves speeding up in deep water.

• Waves bending and changing direction in shallow water.

• Waves disappearing in shallow water.

• Waves maintaining a straight path.

How does wave refraction affect wave energy near headlands?

• Energy is absorbed by the land, stopping the waves.

• Energy remains constant, with no change in wave size.

• Energy is concentrated, leading to bigger waves.

• Energy is dissipated, leading to smaller waves.

What is the result of wave energy being spread out in deep bays?

• Smaller waves and less erosion.

• No change in wave size or erosion.

• Complete disappearance of waves.

• Larger waves and more erosion.

Where is the Mavericks wave located?

• North of San Francisco.

• West of San Francisco, in the Pacific Ocean.

• East of San Francisco.

• South of San Francisco, near Half Moon Bay.

What makes the Mavericks wave famous?

• It is the smallest wave in the world.

• It is located in a desert.

• It is known for its ferocity and size.

• It only forms once a decade.

What is significant about Jay Moriarity's wipeout at Mavericks?

• He surfed the longest wave.

• He fell from a height of sixty vertical feet.

• He discovered a new surfing technique.

• He set a world record for the fastest wave.

What is the key factor in forming big waves at Mavericks?

• The color of the water.

• The temperature of the water.

• The presence of sharks.

• Wave refraction.

What should students do to learn more about the Mavericks wave?

• Interview a surfer.

• Visit the beach.

• Watch the 'Science of Big Waves' video.

• Read a book on surfing.

Why is wave refraction important for surfers?

• It stops waves from forming.

• It forms big surf waves.

• It creates calm waters for swimming.

• It makes waves disappear.
