🌊 Part 1: Wave Formation and Types

1. What causes waves to form in the sea?

Earthquakes under the sea

Wind blowing across the water surface

Fish swimming in large groups

The moon's gravity only

2. Fill in the missing labels for the parts of a wave:

The highest point of a wave is called the ____________.

The lowest point of a wave is called the ____________.

The backward movement of water down the beach is called the ____________.

Constructive waves

Tidal waves

Storm waves

4. Tick all the factors that affect wave size and energy:

Wind strength

🏔️ Part 2: Coastal Erosion and Landforms

5. Explain how destructive waves cause coastal erosion. Include at least two erosion processes in your answer.

Beach

Cliff

Sea cave

Spit

Waves deposit sand in a sheltered bay

Waves erode a vertical rock face

Waves erode a hollow in a cliff face

Waves deposit sediment in a long ridge

7. Give two examples of how coastal erosion can impact human activities:
