3. C

What do you see in the picture?

1. Uprush
2. Backwash
3. Swash
4. Fetch

The wind blows all the way from Florida (USA) to the west coast of France. What name do we use for this distance?

Erosion

Transportation

Deposition

A. This is how waves wear away the coast. The more energy the waves have and the softer the rock, the faster this will be. 

B. This process carries eroded material out to sea, or along the beach – by longshore drift.

C. This process occurs when waves do not have enough energy to transport the eroded material – so it is left behind, forming a beach. 

F. Beaches help to absorb the energy of the waves, which slows down this process, protecting the coastline. 

Abrasion

Solution

Attrition

Hydraulic action

Chemicals in the rock are dissolved by weak acids in the sea water

Sand and pebbles in the waves are flung onto the rock, wearing it away like sandpaper

The energy of the waves forces air and water into the cracks in the rocks, weakening them and eventually breaking them up

The movement of the waves cause the eroded pieces of rock to collide into each other, causing them to become smaller and smaller, until they end up as shingle or sand.

Which landform do you see here?

How is a wave-cut platform formed?

1. The cliff is eroded away, the base stayed behind
2. It formed after softer rock was eroded and deposited again
3. The longshore drift brought rocks and sand to this shallow bay
4. Abrasion and attrition caused the cliff to be eroded. The eroded material formed the platform.

The Zandmotor contributes to coastal protection ...... of it.

Because the longshore drift goes from ..... to .....

1. south south to north
2. south north to south
3. north south to north
4. north north to south

How do these groynes protect the coastline?

Use the words erosion and deposition in your answer.

There are several alternatives for groynes. Why don't we always use groynes?

Give two reasons.

Many products, produced in Asia, are transported through Rotterdam to the Ruhr area.

Which answer is correct?

1. Rotterdam is a mainport
2. The Ruhrarea is a mainport
3. Asia is a mainport.

Many products, produced in Asia, are transported through Rotterdam to the Ruhr area.

Which term belongs to the Ruhr area?

Why is there a bigger risk of a storm surge during full moon? (or no moon)

Sometimes a bulge forms at sea. This can cause a storm surge. What is a bulge, and how is it formed?

Look at the two images. The picture shows the Maeslantkering.
The Maeslantkering is not often closed. Why not?
