This document discusses constructive and destructive waves and their impact on beach profiles. Constructive waves build up the beach by carrying sediment ashore, resulting in a higher and wider beach profile. Destructive waves erode the beach by carrying sediment away, leading to a lower and narrower beach profile. The purpose is to describe the characteristics of these two wave types and explain how each affects the shape of the beach.

2.  1.1aTypes of wave:
constructive and
destructive.

3.  To describe the characteristics
of the two wave types.
 To explain their impact on
beach profiles.

4. Swash and backwash p. 43
Backwash
Swash
Note: Backwash is always at right angles to the beach

5. Types of waves

6. Draw diagrams of constructive and destructive waves, and
label these to contrast the beach profiles and wave height
/wave length.

7. ● Using your arms how can you
demonstrate Constructive and Destructive
waves and their effect on the beach?

8. What do you know about waves?

9.  To describe the characteristics

11. ‘Explain’
When you see a question with ‘Explain’,
1. Check how many marks it is worth.
2. Imagine I said ‘explain how you got to school today’
You would want to ‘explain’, that:
I got in the family car that was driven by my mum , once I had
done that, we drove on the A3. This lead to Kingston hill road
where we turned and parked. As a result of this journey, I arrived
at school on time.
3. By using the connector words, ‘explain’ which type of wave has
reach this coast line.
Remember to use connector words such as:
As a result…
Because of this…
Due to this…
This leads to…
