C2.4: TYPES OF COASTS

Today's goals

1. You can name the 4 spheres and explain what they mean.
2. The landscape is a consequence of the influence of the four spheres. You can give an
   example of all four spheres and how they influence / shape the landscape (see also G93,
   94).
3. Explain how in Normandy, for example, the white cliff coasts are formed (see also G91).

Sedimentary coast

Sedimentary coast

Coast where the waves leave more material behind than they take away.

You can explain how the height and strength of a wave is determined.

"Movement in a body of water, usually caused by wind blowing over the surface."

Height and strenght depend on three factors:

1. Wind force
2. Length of time that the wind blows
3. Distance travelled by waves

Take question 1 + 2 in 

front of you

Question 2

G93: System Earth

All components in on Earth are connected to each other.

Lithosphere: The Earth's crust

Atmosphere: The air around us

Hydrosphere: The Earth's water

Biosphere: Life on Earth

Examples?

You can give an example of all four spheres and how they influence / shape the landscape (see also G93, 94).

Check 3 till 4

Abrasion (cliffed) coast

How are erosion coasts formed?

Take figure 16 in front of you:

1. Waves are crashing onto the lower layers of the cliff.

2. Because of erosion, a hole is formed in the cliff.

3. Salt crystals are left behind in the holes in the cliff.

4. Salt crystals stick together. Because of this, holes and cracks are growing.

5. Holes in the cliff are becoming too big; upper parts are becoming too heavy.

6. A part of the cliff is breaking off.
