Coastal Wave Dynamics and Effects

The video explains factors influencing coastlines, focusing on wave types and their effects. Constructive waves build coastlines by depositing materials, while destructive waves erode them. Longshore drift moves sediment along the shore, influenced by prevailing winds. Various transportation processes like traction, saltation, suspension, and solution are discussed, highlighting how materials are moved in seas and oceans.

Which type of wave is characterized by a low height and long wavelength?

• Seismic wave

• Tidal wave

• Destructive wave

• Constructive wave

What happens to the energy of a constructive wave as it returns to the sea?

• It doubles

• It increases

• It remains the same

• It is completely lost

How do constructive waves contribute to the formation of beaches?

• By eroding the coastline

• By depositing sediment

• By increasing wave height

• By creating tidal waves

Destructive waves are typically formed during which weather conditions?

• Snowy weather

• Sunny weather

• Stormy weather

• Calm weather

What is the main effect of destructive waves on coastlines?

• They erode the coastline

• They build up the coastline

• They create new landforms

• They have no effect

What is the primary factor that determines the direction of longshore drift?
