How Do Some Waves Get SO Big?

The video explores the formation of gigantic waves, focusing on how wave energy extends deep below the surface and interacts with the sea floor. It explains how geological features like reefs and undersea canyons, such as the Nazare Canyon, funnel and compress wave energy, leading to massive wave breaks. The video highlights the unique conditions that create the world's largest waves, particularly off the coast of Portugal.

What happens to wave energy as it approaches shallow water?

• It speeds up and becomes more stable.

• It remains unchanged.

• It dissipates completely.

• It extends above the surface and slows down.

How do underwater geological features like reefs affect waves?

• They have no effect on waves.

• They make waves disappear.

• They compress the wave energy.

• They slow down the waves.

What is the primary role of undersea canyons in wave formation?

• They slow down the waves.

• They dissipate wave energy.

• They create new waves.

• They funnel and amplify wave energy.

What geological feature is responsible for the massive waves off Portugal's coast?

• The Great Barrier Reef

• The Nazare Canyon

• The Mid-Atlantic Ridge

• The Mariana Trench

How does the Nazare Canyon affect wave energy as it approaches the shore?

• It disperses the energy evenly.

• It blocks the energy completely.

• It compresses and launches the energy upwards.

• It redirects the energy back to the ocean.
