Understanding Ocean Waves and Their Properties

This video tutorial explores the significance of waves in coastal geography, explaining how they are formed by wind and their role in shaping coastlines. It covers key wave characteristics such as crest, trough, and wavelength, and discusses the factors influencing wave size, including wind speed, fetch, and duration. The tutorial concludes with tasks and questions to reinforce learning.

Why is it important to study waves in coastal geography?

• They change the shape of coastlines.

• They are important for marine life.

• They influence the weather patterns.

• They are a source of renewable energy.

What primarily creates waves in the ocean?

• Earthquakes

• Rainfall

• Wind

• Tides

Which factor does NOT affect the size of a wave?

• Wind speed

• Duration of wind

• Fetch

• Temperature of water

What is the highest point of a wave called?

• Crest

• Wavelength

• Wave height

• Trough

How is wave height determined?

• By the distance between a crest and a trough

• By the depth of the ocean

• By the speed of the wind

• By the distance between two crests

Which of the following is NOT a part of wave anatomy?

• Trough

• Crest

• Wave height

• Fetch

What happens to frictional drag as wind speed increases?

• It increases

• It remains constant

• It disappears

• It decreases

What causes the ripples on the water surface to form into waves?

• Friction between wind and water

• Underwater currents

• Tidal forces

• Temperature changes

What is the term for the distance over which the wind blows across open water?

• Wavelength
