Ocean Waves and Tides Concepts

Which of these natural phenomena, besides wind, can also cause ocean waves?

• Heavy rainfall

• Moon's gravitational pull

• Strong sunlight

• Changes in atmospheric temperature

What is the primary force responsible for creating most ocean waves?

• Moon's gravitational pull

• Wind

• Earthquakes

• Volcanic eruptions

How does wind transfer energy to the ocean to create waves?

• By pushing water molecules directly towards the shore.

• By creating a vacuum that pulls water upwards.

• By blowing across the surface, transferring some of its energy to the water.

• By causing underwater currents that generate waves.

What is the relationship between wind strength and wave size?

• Stronger wind creates smaller waves.

• The longer the wind blows, the smaller the waves.

• Stronger wind and longer blowing time result in bigger waves.

• Wind strength has no effect on wave size.

How does the energy from wind move through the water in an ocean wave?

• It pushes water in a straight line towards the shore.

• It causes water molecules to move in a circular motion, passing energy to each other.

• It creates a vacuum that pulls water along.

• It directly transports water molecules across the ocean.

What is the most common type of ocean wave?

• Tides

• Tsunamis

• Wind-driven waves

• Underwater current waves

What is the highest part of an ocean wave called?

• Trough

• Peak

• Crest

• Summit

What is the distance from the trough to the crest of a wave called?

• Wavelength

• Amplitude

• Height

• Depth

What is the distance between two consecutive crests of a wave called?

• Wave height

• Wavelength

• Wave period

• Wave frequency

What is the lowest part of an ocean wave called?

• Crest

• Base

• Trough

• Bottom
